Background
• Issues:– Increasing demands vs. declining funds– Shift from capital improvements to
maintenance and preservation– How to make efficient choices for optimum
results
![Page 3: Corridor Management Strategies Pilot in Region 4 Findings and Recommendations Reported to HMT May 2013 By: Martin Matejsek, Laura Wipper, Steve Lindland.](https://reader036.fdocuments.net/reader036/viewer/2022062620/551b157e5503465e7d8b628b/html5/thumbnails/3.jpg)
Background, continued
• Approach to Pilot– Much initial discussion on concept with
leadership teams• Clear boundaries – maintain and preserve

Planning vs. Strategies for Corridors
• Planning Corridor Studies– Focus on
infrastructure improvements
– Public involvement– Coordination with
local agencies
• Corridor Management Strategies– Focus on
preserving and maintaining
– Asset management plan
– Design strategies for preservation

Pilot Corridor – US 97
• Segment Characteristics– NHS Statewide Freight Route– 2010 ADT = 2,000– Rural Two Lane Segments– Narrow Shoulders– Incorporates three smaller
communities• 2015 STIP Project
– Grass Valley to Shaniko

Analysis Based Upon…
• Lots of Data– Asset priority list– Pavement management data– Transportation System Plans– RES/RAZ maps– Contract plans– Vehicle and truck volumes– Crashes and lane departures– Maintenance – drainage and
rock fall issues
![Page 8: Corridor Management Strategies Pilot in Region 4 Findings and Recommendations Reported to HMT May 2013 By: Martin Matejsek, Laura Wipper, Steve Lindland.](https://reader036.fdocuments.net/reader036/viewer/2022062620/551b157e5503465e7d8b628b/html5/thumbnails/8.jpg)
Analysis, continued
• Project team evaluation of assets and design standards
• Safety primary focus– Lane departures (shoulder width)– Bicyclists (shoulder width)
• IHSDM analysis required for corridor standards• Maintenance
– Rock fall (widen shoulders with disposed material)– Culverts blocked with sediment– Drainage (icing issues)
• Freight mobility – Maintain 12’ Lane Width
![Page 9: Corridor Management Strategies Pilot in Region 4 Findings and Recommendations Reported to HMT May 2013 By: Martin Matejsek, Laura Wipper, Steve Lindland.](https://reader036.fdocuments.net/reader036/viewer/2022062620/551b157e5503465e7d8b628b/html5/thumbnails/9.jpg)
Corridor Management Strategies
• Assets and Program Areas addressed:– Bridges– Culverts– Pavement– Flashing beacons– Traffic barriers– Signs– Freight mobility– Unstable slopes or areas with rock fall– Sidewalks and ADA ramps– Shoulder widths and bike facilities– Approaches

Corridor Design Strategies
―Lane width―Bridge width―Horizontal alignment―Vertical alignment―Stopping sight
distance―Spiral length
―Superelevation―Pavement design life―Design life & mobility
standard―Sidewalk width―Median width
Compared to Highway Design Manual• Generally, updated 3R standards appropriate
and substantially met for
![Page 11: Corridor Management Strategies Pilot in Region 4 Findings and Recommendations Reported to HMT May 2013 By: Martin Matejsek, Laura Wipper, Steve Lindland.](https://reader036.fdocuments.net/reader036/viewer/2022062620/551b157e5503465e7d8b628b/html5/thumbnails/11.jpg)
Design Strategy Exceptions
• This segment of US 97 did not meet current 3R standards for – Shoulder width
• Standard is 4 feet, but shoulder width ranged from 2 to 4 feet
– Guardrail shy distance• Standard is 2 feet, but many sections
have none
![Page 12: Corridor Management Strategies Pilot in Region 4 Findings and Recommendations Reported to HMT May 2013 By: Martin Matejsek, Laura Wipper, Steve Lindland.](https://reader036.fdocuments.net/reader036/viewer/2022062620/551b157e5503465e7d8b628b/html5/thumbnails/12.jpg)
Status Quo Question
• How to answer the question, Where can we live with the status quo? – Three goals provided place to start:
• Safety• Mobility• Preservation of existing infrastructure
![Page 13: Corridor Management Strategies Pilot in Region 4 Findings and Recommendations Reported to HMT May 2013 By: Martin Matejsek, Laura Wipper, Steve Lindland.](https://reader036.fdocuments.net/reader036/viewer/2022062620/551b157e5503465e7d8b628b/html5/thumbnails/13.jpg)
Status Quo Filters
• Non-interstate?• Rural route?• Has V/C ratios below OHP targets?• Has not had routine freight movement
requiring traffic control 12 or more times in a year?
• Does not have areas requiring extraordinary maintenance efforts?
• Does not have critical infrastructure below acceptable condition levels?
![Page 14: Corridor Management Strategies Pilot in Region 4 Findings and Recommendations Reported to HMT May 2013 By: Martin Matejsek, Laura Wipper, Steve Lindland.](https://reader036.fdocuments.net/reader036/viewer/2022062620/551b157e5503465e7d8b628b/html5/thumbnails/14.jpg)
Status Quo Suggested Assets/Issues• Bridges• Pavement• Culverts• Traffic Signals• Traffic Barrier• Sidewalks• Bicycle Facilities• ADA Ramps• Unstable Slopes
![Page 15: Corridor Management Strategies Pilot in Region 4 Findings and Recommendations Reported to HMT May 2013 By: Martin Matejsek, Laura Wipper, Steve Lindland.](https://reader036.fdocuments.net/reader036/viewer/2022062620/551b157e5503465e7d8b628b/html5/thumbnails/15.jpg)
Measuring Performance
Suggested measure topics are as follows:– Safety
• Corridor miles with no top 15% SPIS sites (need to develop)
• Lane departure crashes, matching approach taken for 1R Program (match that in development)
– Mobility• Corridor V/C highs (need to develop)• Freight mobility (need to choose or develop)
– Preservation and Maintenance• % Fair or better asset condition • Risk
– Unstable slopes (need to develop)

Specifically Related to Safety
Practical Design
• Safety will not be compromised
• Corridor-basis for safety improvements
• Low-cost mitigation encouraged
Corridor Management Strategies Pilot
• Pilot context: Safety, Mobility, Preservation
• Corridor-basis for safety improvements
• Low-cost mitigation encouraged
![Page 18: Corridor Management Strategies Pilot in Region 4 Findings and Recommendations Reported to HMT May 2013 By: Martin Matejsek, Laura Wipper, Steve Lindland.](https://reader036.fdocuments.net/reader036/viewer/2022062620/551b157e5503465e7d8b628b/html5/thumbnails/18.jpg)
Recommendations – Specific to Pilot Location
• Field verify substandard corridor elements findings
• Establish Corridor Design Exception for Shoulder Width and Shy Distance
![Page 19: Corridor Management Strategies Pilot in Region 4 Findings and Recommendations Reported to HMT May 2013 By: Martin Matejsek, Laura Wipper, Steve Lindland.](https://reader036.fdocuments.net/reader036/viewer/2022062620/551b157e5503465e7d8b628b/html5/thumbnails/19.jpg)
Recommendations – Corridor Management Strategies
• Corridor-based design exceptions rather than corridor-based design standards
• Consider reviewing 4R standards• Evaluate utility and appropriate
application of IHSDM • Continue efforts to bridge Maintenance
and Project Development– Useful sharing of inventory data and issues
![Page 20: Corridor Management Strategies Pilot in Region 4 Findings and Recommendations Reported to HMT May 2013 By: Martin Matejsek, Laura Wipper, Steve Lindland.](https://reader036.fdocuments.net/reader036/viewer/2022062620/551b157e5503465e7d8b628b/html5/thumbnails/20.jpg)
Next Steps
• Refine, define and establish process for programmatic corridor design exceptions analysis– Practical Design Value of Corridor Context
• Apply the process to warranted corridor routes
• Develop methods to share information regularly across business lines regarding significantly sub-standard features
