TRAFFIC AND SAFETY NOTES INTRODUCTION

The Traffic and Safety Support Area maintains these “Notes” as a means of describing practices and procedures, and giving technical guidance to Transportation Service Center (TSC), Region, and Lansing personnel involved in traffic and safety activities. Information contained in the Michigan Manual of Uniform Traffic Control Devices and reference material such as standards, guides, manuals, and specifications are not included in these Notes. These Notes are intended to supplement and provide a basis of application of the above documents to ensure uniformity and do not replace nor supersede any Department Directives, manuals, guides, etc. The Traffic and Safety Notes serve as a guide and do not replace the need for an engineering study or judgment when evaluating a traffic and safety issue. The Traffic and Safety Notes Committee, consisting of Region and Lansing staff, has the responsibility of reviewing and recommending changes to these Notes. Regional/TSC and Lansing staff are encouraged to make their needs for new or revised Notes known to the Traffic and Safety Notes Coordinator or one of the committee members. A new or revised Note will only be issued after a complete review by the affected Lansing unit(s) and all Region Traffic and Safety Engineers and approved by the Traffic Recommendations Committee (TRC) and the Engineering Operations Committee (EOC). These Traffic and Safety Notes will be kept current by adding, removing, and replacing pages, as necessary. Design values are presented in this document in both English (U.S. customary) and metric units. The English values are those that would have been used if the document had been presented exclusively in English units; the metric values are those tha t would have been suggested had the document been presented exclusively in metric units. The relationship between the English and metric values may be an exact (soft) conversion or a rationalized (hard) conversion. Therefore, the user is advised to work entirely in one system and not attempt to convert directly between the two.

TRAFFIC AND SAFETY NOTE 207B SUBJECT: Guidelines for Pedestrian Push Button Use &

Location PURPOSE: To Promote the Uniform Location of Pedestrian

Push Buttons. COORDINATING UNIT: Traffic Signals Unit INFORMATION: When a traffic signal is fully or semi-actuated, or when the time required for pedestrians to cross is the controlling factor in determining the timing of a traffic signal, pedestrian actuation (pedestrian push buttons) should be considered. The Michigan Manual of Uniform Traffic Control Devices (MMUTCD) says pedestrian detectors (pedestrian push buttons) should be conveniently located near each end of the crosswalk where pedestrian actuation is required. The Traffic Signals Unit is now using sign R10-3b or R10-3d with pedestrian actuated signals. This sign shall be mounted above the push button and shall be located so that the arrow points in the direction of the roadway to be crossed. This is normally shown on the signal drawing along with the location of the push button and the correct direction of the arrow. The placement of pedestrian push button signal poles or pedestals will vary depending on the sidewalk layout. This makes it difficult to develop a typical placement of the sign so that all pedestrians can see it. Two possible solutions follow: 1) Two or more signs could be placed so that pedestrians approaching the intersection from any direction would see a sign. 2) At certain locations it may be desirable to supplement the signs with a larger sign attached to the pole or pedestal to call attention to the push button. This sign, above the sign, may say, PUSH BUTTON FOR WALK, and should have a seven foot bottom height. Region/TSC Traffic & Safety Representatives, along with personnel from Traffic Signals Unit, should field review all existing pedestrian actuated signal locations to determine if existing signing is adequate. At new signal locations the location and number of R10-3b or R10-3d signs should be determined at the time of the field layout. Attached are example layouts for push button and sign locations.

221A (2.2.1) 1 of 2 08/05/04

TRAFFIC AND SAFETY NOTE 221A SUBJECT: Resolutions for Cost Participation PURPOSE: Comply with Act 51 Requirements for Cost

Participation COORDINATING UNIT: Traffic Signals Unit INFORMATION: Many smaller governmental agencies are not familiar with all of the information required by the department regarding resolutions for cost participation. In some cases, it has been necessary for the Region/TSC Traffic and Safety Representative to return a resolution to the local agency with a request for additional information. This, of course delays the signal installation. As a result, a form has been prepared which can be used by the various local governmental agencies when approving cost participation in traffic signal installations. The form (see page 2) contains spaces for all of the information necessary for the processing of a Transportation Work Authorization for electronic traffic signal control devices. This is the preferred format, but it is also acceptable if the local agency already is utilizing a form developed by them, that includes all pertinent information. It is necessary that in all cases two signed copies of the resolution document be obtained by the Region/TSC for cost participation from the local agency.

222A (2.2.3) 1 of 1 08/05/04

TRAFFIC AND SAFETY NOTE 222A SUBJECT: Electrical Devices Installed On Construction

Projects PURPOSE: Determine Cost and Design Responsibilities COORDINATING UNIT: Traffic Signals Unit INFORMATION: Any new electrical device or change in the operation of an existing device must be approved by the Traffic Signals Unit prior to completion of the scoping process. Any electronic traffic control device required due to work being done as part of a construction project shall be at the project=s expense (Act 51 Paragraph 247.651c) unless prior approval is given by Traffic and Safety. The project manager shall hire a pre-qualified traffic signal design consultant to design all electronic traffic control devices on the project unless prior approval is given by Traffic and Safety. Due to the difficulty of scheduling the installation of electrical devices in conjunction with construction projects, all new electrical devices and all existing electronic traffic control devices impacted due to a project shall be included in the project. Therefore, the contractor is responsible for the scheduling and erection of the device. The Traffic Signals Unit will review change requests, design, and installation of electrical devices on construction projects.

223A (2.2.4) 1 of 1 08/05/04

TRAFFIC AND SAFETY NOTE 223A SUBJECT: Postcards for Completion Dates PURPOSE: Verify Completion Dates COORDINATING UNIT: Traffic Signals Unit INFORMATION: A postpaid postcard, shown below, is attached by the Traffic Signals Unit to all work authorizations issued to the MDOT-Lansing signal shop, Region/TSC electrician, or contract agencies. It is imperative, following the completion of an installation, that they then fill in the completion date on the postcard and returns it to the Traffic Signals Unit by dropping it in any mailbox. It is not until the Traffic Signals Unit receives these cards that power companies can be notified of wattage changes and the final billing process can take place.

This form is available on MDOT’s internal intranet service. Choose “MDOT Forms Services” under Quick Picks. Enter the form number 1531. The electrician will return post card when work is completed and Traffic Signals Unit will log item into SAFESTAT.

TRAFFIC AND SAFETY NOTE 224A SUBJECT: Notification of Installation of New Traffic Signals PURPOSE: To Alert Motorists to Newly Installed Traffic Signals COORDINATING UNIT: Traffic Signals Unit INFORMATION: Isolated or Outskirts Traffic Signals: Traffic signals that are more than one mile from any other traffic signal or are the first traffic signal encountered when entering an area with signals spaced closer than one mile. 1) SIGNAL AHEAD symbol signs (W3-3) should be considered at the

appropriate distance in advance of the intersection as determined by the Michigan Manual of Uniform Traffic Control Devices (MMUTCD) or at a greater distance as determined by engineering judgment. A permanent panel with the name of the crossroad may be attached under the W3-3 sign.

2) NEW SIGNAL AHEAD signs with a supplemental panel, ½ MILE (or other

distance if appropriate), should be considered in advance of the W3-3 sign. This sign should be removed approximately 90 days after the signal is installed.

3) All signing should be supplemented with fluorescent orange flags to be

removed after 90 days. 4) Battery operated flashers may be considered to supplement the signs. All

supplemental devices should be removed after approximately 90 days. Non-Isolated Traffic Signals: Traffic signals along a corridor where the spacing is less than one mile. 1) If visibility limited or the signal is not expected some or all of the signing

for Isolated Traffic Signals should be considered. 2) W3-3 signs with fluorescent flags should be erected. If visibility is not

limited, this signing should be removed after 90 days. Note: The above conditions apply only to the roadways that did not stop prior to

signalization. W3-3 signs may be erected on the minor legs if deemed appropriate.

All new traffic signals shall be operated in a flashing mode for

224A (2.2.5) 1 of 2 08/05/04

approximately one week before beginning STOP-AND-GO OPERATION. Publicity: A note will be included in all new stop-and-go traffic signal work

authorizations, requesting the installing agency to inform the Region/TSC Traffic and Safety Representative at least two weeks in advance of installation. The Region/TSC Traffic and Safety Representative will then issue an announcement to the appropriate people. (City Manager, Police Chief, State Police, newspaper, radio station, etc.)

Sample Announcement:

NOTIFICATION OF INSTALLATION OF NEW TRAFFIC SIGNAL

The MDOT will be installing a new stop-and-go traffic signal at intersection in city/township/county during the week of month, Monday date and year. The signal will operate in a flashing mode for approximately one week before beginning STOP-AND-GO operation. For further information, please call the MDOT Region Office in city at Phone number.

A representative of the Traffic Signals Unit and the Region/TSC Traffic and Safety Representative will jointly determine the advance warning requirements of the new signal at the time it is approved.

224A (2.2.5) 2 of 2 08/05/04

TRAFFIC AND SAFETY NOTE 261B SUBJECT: Financial Participation in Traffic Signal Mast Arm Poles & Mast

Arms PURPOSE: Assign Cost Participation for Mast Arm Pole Installation COORDINATING UNIT: Traffic Signals Unit INFORMATION: The use of mast arm poles and mast arm mounted traffic signals is allowed if requested by the local governmental agency or when a developer installs a new or modified signal, but costs associated with the installation will be paid by the local governmental agency as listed below: 1) There will be no additional installation cost to the local governmental

agency if all three of the following are met:

A. The department already plans to replace the existing signal heads, span wire, and poles.

B. The mast arm pole and mast arm installations are as economical or

more economical in cost comparison with span wire installations. C. The traffic signal head configuration is acceptable.

2) The local governmental agency will pay for any additional cost to install

mast arm poles and mast arm mounted traffic signals as opposed to span wire mounted signals if the following are met:

A. The department already plans to replace the existing signal heads,

span wire, and poles. B. A span wire installation is more economical than a mast arm

installation. C. The signal head configuration is acceptable.

3) The local governmental agency will pay for all costs associated for the

installation of mast arm poles and mast arm mounted traffic signals if the following is met:

A. The department has no current plans to replace the existing signal

heads, span wire, or poles. B. The signal head configuration is acceptable.

261B(2.5.1) 1 of 2 8/17/2006

4) The local agency will pay a biennial fee (estimated at $500 per structure with a 3% increase per year) to cover costs of structural inspection for Category II or Category III mast arm pole and mast arm installations. Inspection will be according to the Michigan Department of Transportation’s Procedure for Inspection of Traffic Signal Mast Arm Poles and Mast Arms. This fee will be billed to the local agency by MDOT. The local agency must submit an Advance Resolution to MDOT acknowledging these costs prior to installation of the structures.

When existing traffic signal mast arm poles and mast arm installations are replaced, the local governmental agency is responsible for any additional costs due to the mast arm pole and mast arm installation. If the local governmental agency is not willing to pay for any additional costs, a span wire mounted traffic signal will be installed. Due to the limited length of mast arms, they are not suitable to all intersections. If an acceptable traffic signal head configuration cannot be obtained with mast arms pole and mast arms, they will not be allowed regardless of cost.

262A (2.5/NEW) 1 of 1 08/05/04

TRAFFIC AND SAFETY NOTE 262A SUBJECT: Financial Participation in Traffic Signals Due to

Operational Changes PURPOSE: Assign Cost Participation Due to Operational

Changes COORDINATING UNIT: Traffic Signals Unit INFORMATION: When an operational change to a traffic signal is required due a project not initiated by the department, such as widening of a local road crossing a trunkline or signal modifications due to a development, all costs associated with the modifications shall be at the cost of the local governmental agency or the developer. If the controller is not adequate to handle the new operation or if the controller is 10 years old or older, the controller along with the cabinet will be replaced at no cost to the department. All requests of this type should be processed as a permit to work within MDOT Right-of-Way. The Traffic Signals Unit will assign costs due to operation changes.

263A (2.1.6) 1 of 2 08/05/04

TRAFFIC AND SAFETY NOTE 263A SUBJECT: Termination of Traffic Signal Cost Agreements PURPOSE: To Notify all Necessary Parties that an Electrical

Device or Traffic Signal has been Removed COORDINATING UNIT: Traffic Signals Unit INFORMATION: This note defines a procedure and provides a sample letter to notify all necessary parties of the removal of electrical devices. Once the electrical device or traffic signal is removed, records and files need to be updated to eliminate the possibility of paying future maintenance and utility costs on the removed device. When a traffic signal is removed, upon receipt of the work authorization completion date from the Maintenance Division, the Traffic Signals Unit will prepare and mail the attached letter to the participating, maintaining, and billing agencies identified on the existing cost agreement.

TRAFFIC AND SAFETY NOTE 903B SUBJECT: Maintaining Traffic During Roadway Work at

Railroad Crossings PURPOSE: Consistent and Proper Maintaining Traffic Schemes at Railroad Crossings COORDINATING UNIT: Governmental and Railroad Coordination Unit INFORMATION: Railroad crossings need to be considered early in the design process. The application of this guideline is intended for projects where traffic maintenance during construction is temporary (i.e., less than one day’s duration) and actively conducted such as with a traffic regulator. Examples of these types of projects include mill and resurface jobs where all lanes are open at night and preventative maintenance crack overbanding and spot patching jobs. Unattended traffic shifts accomplished by signing and arrow panels at crossings, roadway widenings, and/or concurrent railroad work require more extensive considerations than described in this guideline. For such projects, contact should be made to Lansing Design’s Trunkline Crossing Program for their assistance. The common practice of ‘gapping out’ the crossing area in the project work limits is not recommended. Extending the work limits to the edge of the crossing surface only adds approximately $2,000 (2003 dollars) to the roadway project and results in a contiguous segment of refurbished roadway. It costs many times this amount to develop a stand-alone project to refurbish 15 ft (4.6 m) of pavement on both crossing approaches at a later date. Design of a roadway project should consider two types of possible impacts upon the crossing environment. The first consideration is whether or not construction work is intended to take place within 15 ft (4.6 m) of the live rail 25 ft (7.6 m) for crossings with the Canadian National/Wisconsin Central Limited (CN/WCL). If roadway construction equipment operates closer than these limits, a railroad watchperson must be present and it is the contractor’s responsibility to obtain and pay for this service as described in the COORDINATION CLAUSE FOR RAILROAD WORK document in the project proposal. The main purpose of a railroad watchperson being present during construction adjacent to the crossing is to ensure the crossing is clear of construction equipment and safe for train passage. A secondary function may be to inform the contractor well in advance of approach train movements. Typical charges for a railroad watchperson are $100 per 8 hour day to $900 per 8 hour day (2008 dollars). In addition to the contractor obtaining the services of a railroad watchperson, the contractor will be required by the railroad to purchase an insurance policy against

903B (12.1.5) 2 of 6 7/08/08

damage to railroad equipment and facilities as described in the SPECIAL PROVISION FOR RAILROAD PROTECTIVE LIABILITY INSURANCE document, also in the project proposal. The cost of such a policy is on the order of $4,000 (2008 dollars). The NOTICE TO BIDDER document in the project proposal provides the train speed and frequency information necessary for the contractor to estimate the cost of railroad protective liability insurance in bidding the roadway work. The manner by which traffic will be maintained at the crossing during construction needs to be considered. Maintaining traffic issues can arise even if no physical construction work is performed in the vicinity of the crossing. An example of this situation is where a long traffic regulator zone on a two-lane two-way roadway contains a crossing. When traffic is running reverse to normal travel, the normal right-hand approach display of railroad warning devices at the crossing is then on the far left departure side of the crossing. In order to maintain a consistent message as to the stopping point to the motorist, contractor stationing of an intermediate roadway traffic regulator is required as described in the paragraphs entitled “SPECIAL CONSIDERATIONS AT RAILROAD CROSSING” to be inserted into the Special Provision for Maintenance of Traffic. Please see page 4 of these notes. Insert “A” is appropriate when traffic regulator zones will occur over the crossing while insert “B” is appropriate when a traffic regulator is not used.

When referring to the crossing, use the “G O Number” (Crossing Number of the Control Section) or the National Inventory Number (NI#) rather then the grade crossing milepoint. The NI# will be located on a tag the size of a motorcycle license plate, in a format of six digits and a letter, on one of the flasher masts, crossbuck posts, or nearby utility pole.

Four possible project scenarios and the appropriate railroad related bid

documents are illustrated in the following examples.

1) Milling to crossing surface on roadway, traffic maintained by traffic regulator. The following should be included in the bid package: SPECIAL CONSIDERATIONS AT RAILROAD CROSSING to be inserted into the Special Provision for Maintenance of Traffic – Format A, COORDINATION CLAUSE FOR RAILROAD WORK, SPECIAL PROVISION FOR RAILROAD PROTECTIVE LIABILITY INSURANCE, and NOTICE TO BIDDER (with Train Speed and Frequency)

2) Milling to crossing surface on roadway, traffic maintained by detour. The following should be included in bid package: SPECIAL CONSIDERATIONS AT RAILROAD CROSSING to be inserted into the Special Provision for Maintenance of Traffic – Format B, COORDINATION CLAUSE FOR RAILROAD WORK, SPECIAL PROVISION FOR RAILROAD PROTECTIVE LIABILITY

903B (12.1.5) 3 of 6 7/08/08

INSURANCE, and NOTICE TO BIDDER (Train Speed and Frequency).

3) No roadway construction work near crossing, traffic maintained by traffic regulator. The following should be include in bid package: SPECIAL CONSIDERATIONS AT RAILROAD CROSSING to be inserted into the Special Provision for Maintenance of Traffic – Format A, COORDINATION CLAUSE FOR RAILROAD WORK, and NOTICE TO BIDDER (Train Speed and Frequency)

4) No roadway construction work near crossing, traffic flow is in normal state in vicinity of crossing but crossing is within project limits or near beginning/ending of project limits. The following should be include in bid package: SPECIAL CONSIDERATIONS AT RAILROAD CROSSING to be inserted into the Special Provision for Maintenance of Traffic – Format B, COORDINATION CLAUSE FOR RAILROAD WORK, and NOTICE TO BIDDER (Train Speed and Frequency)

The railroad related bid documents and select pages of the plans are transmitted to the railroad. Sending the documents generated to the railroad and indicating the type of work and anticipated construction period serves to allow the railroad to coordinate any maintenance activities they have scheduled along with identifying the extent of requests for railroad watchpersons for the construction season. A copy of the transmittal letter should be submitted at the time of certification bid turn-in in the project’s acceptance/certification package.

See also Section 462.309 of Act 354 of 1993 for background information (see page 5 and 6 of this note and/or www.michiganlegislature.org) which defines the railroad and road authority responsibilities in state law. The Department also has Master Agreements and Maintenance Contracts with most operating railroad which further defines the railroad/road authority relationship. For information on the Master Agreements and Maintenance Contracts, please contact Lansing Design’s Trunkline Crossing Program. For more information on work zone management see the Work Zone Safety and Mobility Manual.

903B (12.1.5) 4 of 6 7/08/08

Maintaining Traffic Inserts: Special Considerations at Railroad Crossings Insert A: An intermediate traffic regulator will be needed at the railroad crossing while it is in a zone where traffic is maintained by traffic regulator control or while traffic shifted in a direction opposed to normal flow through signage. Every effort should be made by the contractor’s construction methods as to not obstruct the right-hand display of the railroad signal to traffic approaching the crossing. The intermediate traffic regulator shall serve to stop traffic for vehicles traveling in the direction opposed to normal flow and prevent them entering the crossing upon a train approaching the crossing. The contractor shall place a temporary stop line to indicate the stopping point in advance of the crossing for vehicles traveling in a direction opposed to normal flow. The intermediate traffic regulator(s) and temporary stop line(s) are considered incidental to Flag Control and will not be paid for separately. The contractor is responsible for contacting the applicable railroad to obtain and pay for a railroad watchperson as described in the Coordination Clause for Railroad Work when construction activities are within 15 feet (4.6 m) from the outside rail on either crossing approach (25 feet (7.5 m) for CN/WCL). When the railroad crossing is in the influence zone of active construction work, but not in a lane closure, the traffic regulator shall give immediate preference to clearing any traffic which backs-up over the crossing as a result of the traffic regulator control away from the crossing. No lane closure taper(s) may extend through the crossing. Traffic lane shifts cannot transition over the crossing. No construction traffic control devices may be placed in the railroad crossing or closer than 15 feet (4.6 m). Insert B: When the railroad crossing is in the influence zone of active construction work, but not in a lane closure, the traffic regulator shall give immediate preference to clearing any traffic which backs-up over the crossing as a result of the traffic regulator control away from the crossing. No lane closure taper(s) may extend through the crossing. Traffic lane shifts cannot transition over the crossing. No construction traffic control devices may be placed in the railroad crossing or closer than 15 ft (4.6 m) from the outside rail on either crossing approach.

RAILROAD CODE OF 1993 (EXCERPT)

Act 354 of 1993

462.309 Maintenance, renewal, and repair of roadbeds, tracks, culverts, and certain streets or sidewalks. Sec. 309. (1) A railroad owning tracks across a public street or highway at grade shall at its sole cost and expense construct and thereafter maintain, renew, and repair all railroad roadbed, track, and railroad culverts within the confines of the street or highway, and the streets or sidewalks lying between the rails and for a distance outside the rails of one foot beyond the end of the ties. The road authority at its sole cost and expense shall construct or improve if necessary and thereafter maintain, renew, and repair the remainder of the street or highway. (2) The space between the rails and for a distance outside of the rails of one foot beyond the end of the ties shall be surfaced with a material which shall be as durable and as smooth as the adjacent street or highway surfacing, and shall have minimum qualifications not inferior to wood planks, and shall conform, as nearly as reasonably may be, to the configuration of the adjacent street or highway. In the case of streets and highways constructed or reconstructed after the effective date of this act, the surfacing of planks or other material shall have a minimum length equal to the length between the established curb lines, or, in the absence of curb lines, equal to the length between the established shoulder lines of the street or highway plus two feet on each side of the street or highway. (3) The full cost of maintaining and repairing all existing crossings shall be borne by the respective parties responsible for the work as provided in this act. The cost of improving an existing crossing, where improvement is necessary, shall be borne in the same manner as provided in this act for maintenance and repair. (4) Any alteration in the existing elevation of the top of railroad track or highway surface in excess of one inch shall be mutually determined by the railroad and road authority, but in case of failure to agree, the parties may apply to the department which may provide for the alteration after hearing. Where the change in elevation of track rails is agreed upon or authorized for purposes other than to conform to the configuration of the adjacent street or highway, the entire cost shall be borne by the party requesting the change. (5) The railroad shall not perform any work, except emergency repairs, on public streets or highways between the established curb lines, or, in the absence of established curb lines, between the established shoulder lines of the street or highway, without first notifying the road authority having jurisdiction over the

903B (12.1.5) 6 of 6 7/08/08

street or highway, and without first providing and thereafter maintaining the necessary traffic controls in accordance with the Michigan Manual of Uniform Traffic Control Devices. The railroad plan for maintaining traffic showing the necessary barricades, lights, flaggers, and traffic detours and other traffic controls shall be approved by the road authority before the work begins. (6) In cases of sidewalk repair or construction, a railroad shall first be given the right to construct in the same manner as that right is given to individuals, and if it fails, the local unit of government may cause the sidewalk to be constructed at the expense of the railroad, with the cost to be collected in the usual manner as provided in the law governing that local unit of government. In the case of the construction of a railroad upon any public street, lane, alley, or highway, the same shall be on such terms and conditions as shall be agreed upon between the railroad company and the governing body of any city, or the village board of any village, or the township board of any township and appropriate road authority in which the railroad is located; but the railroad shall not be constructed upon any public street, lane, alley, highway, or private way until damages and compensation are made by the railroad company to the owner or owners of property adjoining the street, lane, alley, highway, or private way and opposite where the railroad is to be constructed either by agreement between the railroad company and each owner or owners, or as otherwise provided in this act for obtaining property or franchises for the purpose of constructing a railroad. (7) Nothing in this section shall prohibit a road authority, at its discretion and sole cost and expense, from performing any of the work described in this section provided that the road authority receives approval from and gives notice to the railroad. (8) Notwithstanding any other provision of this section, neither the railroad nor the road authority shall charge any type of access fee, inspection fee, or right of entry fee in connection with the performance of work described in this section.

SUBJECT: Construction Zone Checklist for Traffic Controls

PURPOSE: To Promote the Uniform Evaluation of Traffic

Control in Construction Project Areas COORDINATING UNIT: Traffic Signs & Delineation INFORMATION: In order to assist persons responsible for providing continued effective traffic control through construction project areas, a Construction Zone Checklist has been developed for use in the field. A copy of the checklist is available from the Work Zone Administrator at the Construction and Technology Office (Brain Zimmerman as of 2004). A new Construction Zone Checklist should be obtained every year to ensure that the latest version is being used. The Construction Zone Checklist should be used by Lansing and Region/TSC Traffic and Safety personnel for field review of traffic control in construction areas. Recommendations for adjustment to any feature of the traffic control plan for a particular construction project should be referred to the Project Engineer for consideration. Region/TSC Construction personnel should also be encouraged to employ this checklist for periodic review of traffic control throughout construction projects.

TRAFFIC AND SAFETY NOTE 907B SUBJECT: Incentive/Disincentive Clause PURPOSE: To Provide Guidance for Calculating Capacity in

Determining if an Incentive/Disincentive is Warranted

COORDINATING UNIT: Geometric Design Unit INFORMATION: To justify an incentive/disincentive (I/D) clause, delay-related user costs must exceed the I/D dollar amount. Generally, the I/D dollar value should not exceed five percent of the construction contract. Determining the impact on capacity may also be useful in determining the impact on the Central Business District or as a Context Sensitive Measure. The attached information can be used as an initial tool to estimate capacity in determining whether or not an I/D clause is warranted for a construction project. Please also see Note 901-Series for Guidelines for Maintaining Traffic Capacity. For more information on work zone management see the Work Zone Safety and Mobility Manual.

GUIDANCE FOR CALCULATING CAPACITY in DETERMINING if

an

INCENTIVE/DISINCENTIVE CLAUSE

Is WARRANTED

The attached tables can be used as an initial tool to estimate capacity in determining whether or not an incentive/disincentive (I/D) clause is warranted for a construction project. To justify the clause, delay-related user costs may exceed the I/D dollar amount. Generally, the I/D dollar value should not exceed five percent of the construction contract. Normally, congestion occurs each time traffic demand exceeds the capacity of the roadway under consideration. Since the Design Hourly Volume (DHV) is readily available, it can be used and compared to the appropriate capacity presented in the attached tables. When DHV exceeds available capacity, an incentive/disincentive analysis can be performed to determine the amount of user delay. Twenty-four hour counts and the maintaining traffic plan are required to perform this analysis. Currently, the department uses the construction congestion (C03) program to estimate total user delay cost associated with construction activities. (Contact the Traffic and Safety Region Services area of Construction & Technology for more information on the C03 program.) The total delay cost calculated by this program is the sum of speed and backup delay. Speed delay is the difference in time to travel the distance through a work zone (or around it if a detour is required) during construction and the time it would take if there were no construction. Backup delay is the length of time a vehicle spends in queue before entering a work zone. Backup delay occurs when traffic demand exceeds work zone capacity. If a designated detour is present, a traffic distribution model should be used to estimate traffic volumes using the detour and traffic volumes still traveling through the work zone. The C03 program can then be used to estimate user costs.

CAPACITY DURING TRAFFIC REGULATING OPERATIONS

Attached is a chart and graph showing capacity during traffic regulating operations on two-lane roadways. The capacity of a traffic regulating operation is directly related to the length of the traffic regulating zone. For example, if the posted speed during the traffic regulating operation is 35 mph and traffic demand is 1,000 vph, the length of the traffic regulating operation should not exceed 0.7 miles (1.12 km). The C03 program can be used to calculate user delay.

TRAFFIC AND SAFETY NOTE 908A SUBJECT: Capacity in Traffic Regulating Zones PURPOSE: To Provide Guidance in Traffic Regulating Zone Length

Selection COORDINATING UNIT: Geometric Design Unit INFORMATION: Traffic regulating zone capacity is directly related to the length of the traffic regulating operation. By selecting a capacity equal to or exceeding traffic demand, the Engineer can determine the required length of the traffic regulating operation. Attached are a chart and graphs showing capacity during traffic regulating operations. This chart was based on the EXCEL program developed for our department by the University of Michigan. For example, if the posted speed during the traffic regulating operation is 35 mph and traffic demand 1,000 vph, the traffic regulating operation zone length should not exceed 0.7 miles (1.12 km). Please note the chart does not apply to roadways which included signalized intersections.

TRAFFIC AND SAFETY NOTE 909B SUBJECT: Incident Management Route Signing PURPOSE: To Promote Uniformity in the Placement of Route

Signing for Incident Management COORDINATING UNIT: Traffic Signs and Delineation Unit INFORMATION: The proper placement of incident management route signing is crucial in the successful implementation of an Incident Management Plan for closure of a roadway due to an emergency. To ensure uniformity on diversion routes, the appearance of incident management route signing shall be in accordance to the current edition of the Michigan Manual on Uniform Traffic Control Devices (MMUTCD). All route sign auxiliaries shall match the color combination of the route sign they supplement except the EMERGENCY auxiliary sign (M4-7f). The EMERGENCY auxiliary shall be a black legend and border on a fluorescent orange background sign mounted on top of the route assembly. See the current edition of the department’s Standard Highway Signs book for a layout of this sign. Placement of Incident Management Route signs can be done either through permanently installed or temporary signing. For freeway diversion routes, permanently installed signing is recommended. For non-freeway, permanent signs should be considered on the following factors:

• Key routes • High ADT roadways with documented repeated incidents • Roadway utilizing long detours

Permanently installed fold down signs are not recommended due to the limited resources available to implement the plan and close the signs after the incident. In addition, maintenance issues regarding these types of signs do not lend them to be used as standard signing. The location of Incident Management Route Signing shall follow the MMUTCD requirements in Part 2D except the conforming assembly. Additional information is also available in Appendix D of Traffic Sign Design Placement and Application Guidelines. Due to the occurrence of overlapping incident management routes, the motorist may be faced with a route turn and a straight through confirming message. Therefore, the confirming assembly should be placed 500 feet to 1,000 feet (150 m to 300 m) beyond the intersection to minimize motorist confusion at key decision points. The frequency of confirming assemblies should be limited to major intersection/key crossroads and at a frequency determined by the Region Traffic and Safety Representative to ensure continuity of the diversion route. Examples of Incident Management Route Signing are illustrated on page

909B 2 of 5 7/08/08

three, four and five of this note. The Region Traffic and Safety Representative should discuss the proposed incident management route with the local road authority representatives, potentially affected by these routes, to ensure that they are agreeable to what is being proposed. Written permission should be obtained from the local agency to use non-trunkline roads in the proposed incident management route. Features, such as, but not limited to, the roadway geometrics, structure underclearances, and weight limits, should be considered when determining the proposed incident management route. Consideration should be given to developing unique routes for each direction of travel. Unique routes may improve traffic operations by minimizing potential left turn locking. The Region Traffic and Safety Representative should remain in contact on a regular basis with the local agency to determine if adjustments are needed to the incident management route because of local road construction.

TRAFFIC AND SAFETY NOTE 1001B SUBJECT: Traffic Crash Data Request PURPOSE: Requesting and Obtaining Crash Data for Investigations COORDINATING UNIT: Safety Programs Unit INFORMATION: Requests for Traffic Crash Data typically fit into following categories:

• To conduct crash analysis on department construction projects,

• To conduct a department funded study,

• To conduct a non-department funded study, and

• FOIA request Requests for crash data to conduct crash analysis on department construction projects, including those being done by consultants, should be made to the MDOT Project Manager. Requests for department funded and non-funded (but supported by the department) studies should be made to the Technical Services Unit (TSU) of the Safety Programs Section. The request can be in the form of a phone call, e-mail, regular mail, or fax. The request for Traffic Crash Data should include information describing in detail what is being requested. This might include: control section or PR numbers and milepoints, crossroads or project limits, and any other boundaries describing the area of interest. The requester should also indicate the format desired, such as: one-line listings, UD-10s, etc. Requests for data through the FOIA process are to be submitted to the Office of Communications. Information on the restricted use of crash data and studies that result from this data can be found in Traffic Safety Note 1103A. Beginning with the year 2001 crash data, approved users may access the UD-10 images online via TMS (or CRIS within TMS). The images are available for dates within approximately three months of the current date. As additional years of UD-10 images become available, 10 years will be maintained. For training on how to access UD-10 crash images contact the Safety Programs Unit.

REQUIRED ELEMENTS OF A COMPREHENSIVE DESIGN EXCEPTION REQUEST CRASH ANALYSIS

1) Subject heading which includes a description of the project (route number, control section, P.R. number, control section and P.R. beginning and

ending mile points, and job number). 2) A statement that the crash analysis is in relation to a specific design

exception request (as opposed to a project wide analysis). 3) A statement indicating which geometric feature the design exception has been requested for, and the location to which it applies (Control Section or P.R. number and mile points). 4) A description of the existing condition or value of the geometric feature in question. 5) A description of the proposed condition or value of the geometric feature in question. 6) A statement detailing what the standard value is for the geometric feature in question, and a reference to the appropriate governing Standard or Guide. 7) A description of the crash data used in the analysis (time span and mile point limits of the data query). This should be the most recent four years for which crash data is available, using the Safety Management System in TMS. 8) A summary of the total numbers and types of crashes found in the analysis. 9) A statement that the crash types associated with the geometric feature in question were specifically investigated in detail. Refer to Table A to determine which crash types are associated with which geometric features. This detailed investigation shall include a review of all crash reports (UD-10’s) for these crash types. If there are a large number of crashes of the associated types, a representative sample of UD-10’s may be selected for review (as opposed to all of them). 10) A statement that the analysis did not (or conversely, did) find a pattern or concentration of crashes associated with the geometric feature for which the design exception has been requested.

* At night, the available sight distance through sag vertical curves is largely determined by headlight illumination distance. Therefore, when reviewing crashes in relation to sag vertical curves, particular attention should be paid to night-time crashes, including animal collisions. A high percentage of night-time crashes could indicate a crash pattern related to insufficient stopping sight distance. While animal collisions are not generally included in crash analyses due to the large uncertainty as to their causes and/or exact locations, they should not be summarily dismissed, either. Animal crashes can be taken with together with the crash data set as a whole, and can sometimes help identify crash patterns specifically related to restricted sight distance. When performing a crash analysis as part of a design exception request, focus the review on the crash types which are associated with the geometric feature in question. Use the table above to determine which crash types are associated with each geometric feature. Also, consider only the crashes which have occurred in the vicinity of the subject geometric feature (not necessarily project wide). It is usually sufficient to set the mile point limits of the crash data query to a few hundred feet on either side of the geometric feature in question. Crash analysis is, by its nature, an inexact and subjective exercise. There will often times be uncertainty as to whether or not a particular geometric feature contributed towards a given crash. The information provided in the UD-10’s, along with engineering judgement, can usually resolve any questions adequately.

Crash Analysis: US-55, First Street to Brownville Drive C.S. 92053, Mile Points 1.62 – 3.76 PR# XXXXX, Mile Points X.XX – X.XX J.N. XXXXX

A crash analysis has been completed for a spot location within the subject roadway segment. This analysis focuses on the crash history at this location as it relates to a design exception request. A more general safety analysis spanning the entire project limits should have been completed as part of this project’s 3R/4R Safety Review.

A design exception has been requested to retain an existing normal crown cross-slope through a horizontal curve from mile point 2.58 to mile point 2.74. Current standards call for minimum (Straight-Line) superelevation rate of 3.5% for this curve. Crashes which occurred between these mile points, and within 500 feet on either side, were considered in this review. Four years of crash data (January 1, 2002 through December 31, 2005) was used in the analysis of this location. During the four-year study period, There were 92 total crashes within the limits described above. These consisted of 41 rear-end, 15 angle, 15 sideswipe, 7 head-on left-turn, 4 fixed-object/overturn, 2 pedestrian, and 8 miscellaneous type crashes. Crash types which are typically allocated with the lack of superelevation, or with inadequate superelevation rate, were specifically investigated in detail. Such crash types include sideswipe, fixed-object, overturn, and other crashes which indicate loss-of-control or inability to maintain the desired path of travel. A detailed review of the crash reports for these crash types revealed that the vast majority of these collisions were not caused by a loss of control or failure to maintain vehicular path. Of the 15 sideswipe crashes, 7 were caused by improper lane changes or by vehicles attempting to turn from the wrong lane 4 were the result of parallel parking maneuvers, 1 was alcohol related, and 1 was actually a miscoded angle-turn crash. Only two of the sideswipe crashes were unexplained, or the possible result of a loss-of-control. Of the four fixed-object crashes, one was due to icy conditions, and one was caused by excessive speed. Two of the fixed-object crashes were unexplained, or the possible result of a loss-of-control. In summary, there is no crash pattern, or any other evidence, indicating that the absence of superelevation (normal crown cross-slope) is either causing, or significantly contributing to, crashes at this location.

Crash Analysis: M-87 Settlement Road to Greenbelt Parkway C.S. 92054, Mile Points 25.25 – 26.25 PR# XXXXX, Mile Points X.XX – X.XX J.N. XXXXX

A crash analysis has been completed for the subject roadway segment. This analysis focuses on the crash history at this location as it relates to a design exception request. A more general safety analysis spanning the entire project limits should have been completed as part of this project’s 3R/4R Safety Review. A design exception has been requested to retain the existing non-standard shoulder slope on the outside (southbound side) of a horizontal curve located within the subject roadway segment. Currently, this shoulder slopes at 1.0%, away from the traveled way. This results in a 6.2% grade-break (roll-over) with the mainline pavement, which is superelevated at 5.2% in the opposite direction. Standard Plan R-107-E specifies that the shoulder slope should match the cross-slope of the mainline pavement (5.2% in the same plane). Standard Plan R-107-E further stipulates that the roll-over between the shoulder and the traveled way should not exceed 6.0%. Four years of crash data (January 1, 2002 through December 31, 12005) were analyzed for the one-mile section of roadway which includes the subject horizontal curve. The crash history was reviewed to ensure that there are no patterns or concentrations of crashes attributable to, or compounded by, the non-standard shoulder slope and/or roll-over value. During the four-year study period, there were 12 total crashes within the subject roadway segment. These consisted of one sideswipe-opposite, three fixed-objective run-off road, and eight animal crashes. Crash types which could be indicative of excessive roll-over or cross-slope differential were specifically investigated in detail. Such crash types typically consist of fixed-objective/run-off road, overturn, and any other crashes which indicate a loss-of-control or departure from the roadway. A detailed review of the crash reports for these crash types revealed that the collisions were not related to the design feature in question. All three fixed-object/run-off road crashes involved northbound vehicles. Therefore, these crashes are not attributable to the southbound shoulder slope or roll-over. The sideswipe crash was also reviewed, to ensure it was not caused by a southbound vehicle which was drawn onto the shoulder and which then over corrected back across the centerline and into the northbound lane of travel. In fact, this crash occurred on the bridge over the Hopeful River, and involved contact between the side-view mirrors of two trucks; it was in no way related to the design feature in question. In summary, there is no indication that the non-standard cross-slope and/or roll-over rate of the southbound shoulder has either caused, or contributed to, crashes at this location.

SUBJECT: Design Exception Analysis Review

JN XXXXXA - CS 95292

This office has reviewed the Crash Analysis as submitted by the design consultant PQRS Engineers dated November 31, 2005 for the above referenced project. The design exception reviewed was for Acceleration/Deceleration Length Design. The Crash analysis indicated that it did not review the UD-10’s and therefore was unable to determine if a definitive crash pattern related to the design exception requested exists. Therefore, in review of this analysis, this office did conduct a through review of all of the UD-10’s for the listed PR numbers and mile points of the Crash Analysis. Of all of the UD-10’s reviewed, there were five crashes that occurred at or near the merge point of Ramp E and NB I-87. Four of the crashes were related to inclement weather/roadway conditions (three icy/snow and one rain). The other crash appears to be a driver medical condition resulting in the crash. Of all the UD-10’s reviewed, there is no correctable crash pattern associated with the requested Design Exception for Acceleration/Deceleration Length Design. As the design is to significantly improve the existing acceleration taper from 725 feet to 1209 feet (50 feet shy of required), this office has no objection to the conclusion and recommendations of the Crash Analysis as presented.

TRAFFIC AND SAFETY NOTE 1102A SUBJECT: Legal Terms

PURPOSE: Definitions of Legal Terms to Inform Employees Involved in Litigation Activities of Legal Meanings of Words

COORDINATING UNIT: Safety INFORMATION: Below is listed a glossary of terms with which an expert should be familiar: Admission - The confession or voluntary acknowledgement made by a party to a civil action either orally, in writing, or by action, as to the existence or truth or certain facts. Answer (Affirmative Defenses) - The document filed by the defendant in answer to the charges in the complaint, in which the allegations of the complaint either are admitted or are denied. Appellate Court - A court that reviews the law as applied to a prior determination of the same case. Burden of Proof - That degree of proof necessary to prove the issues. In civil proceedings, the burden of proof is to prove the issue by a preponderance of the evidence. This standard is less stringent than in a criminal case, where the state is required to prove its case beyond a reasonable doubt. Civil Action - An action instituted to recover for violation of a private or civil right or the failure to perform a legal duty by active or passive negligence. Any action that is not criminal is said to be a civil action. Complaint - The document filed in court at the beginning of a lawsuit that contains the charges against the defendant. This complaint provides notice to the defendant of the wrongs alleged to have been committed by him/her. Cross Examination - The questions asked a witness by the attorney who is opposing the attorney who has presented the witness, after direct examination has been completed. Defendant - The party being sued. Deposition - A procedure whereby an opposing attorney may question a witness under oath for the purpose of giving the opposing side information regarding the case. Questions are asked by the opposing attorney as though the witness were

1102A (19.1.1) 2 of 3 08/05/04

under oath at trial under cross examination. This procedure is conducted prior to trial and aids the parties to the lawsuit by providing them with a better understanding of the claims of the opposing side. This procedure is intended to simplify and clarify the issues at trial. Direct Examination - The sequence of questions asked of the witness by the attorney who has called him/her to the witness stand for his/her side of the case. Evidence - All testimony from witnesses allowed by the judge, as well as all documents, papers, photographs, etc. which the judge has allowed to be admitted. Impeachment - A technique of questioning by an opposing attorney during cross-examination intended to discredit testimony by demonstrating that the witness has made previous oral or written statements contradictory to his testimony at trial. Interrogatories - In civil actions, a pretrial discovery tool in which written questions are prepared by one party and served on the adversary, who must serve written replies under oath. Interrogatories can only be served on parties to the action, and while not as flexible as depositions, which include opportunity of cross-examination, they are a good and inexpensive means of establishing important facts held by the opposite party. Negligence - Failure to exercise the standard of care that would be expected of a normal person in similar circumstances. Objection - The expression used by an attorney to the judge to express the opinion that the opposing attorney is not complying with one of the formal rules of evidence. Objection Overruled - The expression used by the judge to indicate that the question, answer, document, or other evidence to which an attorney has objected will be admitted or allowed. Objection Sustained – The expression used by the judge to indicate that he agrees with the attorney making the objection. Plaintiff - The party suing. Prosecutor - A public official who prepares and conducts the legal proceedings. The basic role of the prosecutor is to seek justice, not convictions. He or she is charged with the duty to see that the laws are faithfully executed and enforced.

Recross Examination - The sequence of questions following redirect examination asked by the attorney who questioned on cross examination. Normally, the scope of recross examination is confined to information elicited on redirect examination.

1102A (19.1.1) 3 of 3 08/05/04

Redirect Examination - The questions following cross examination asked by the attorney who conducted the direct examination. Redirect examination is normally confined to issues raised on cross examination, and is used to clarify or elaborate upon answers made by the witness during cross examination or to rehabilitate the witness after impeachment during cross examination. Subpoena - An order issued by the court requiring a person to appear in court at a particular time and place as a witness. Subpoena Duces Tecum - An order by the court requiring a person to appear in court at a particular time and place and bring specified records for use during a case. Summons - The official notice served upon the defendant notifying him of the lawsuit. Testimony - A statement made by a witness under oath. Tort Action - The name given to a civil action to recover for injury to person or property arising from breach of a legal duty. Trial - The examination of testimony and applicable law by a competent tribunal to determine the issue of specific charges or claims. Witness - The party testifying on the witness stand.
