1. Foreword 1.1 Interim Advice Notes (IANs) may be issued by Ashghal from time to time. They define

specific requirements for works on Ashghal projects only, subject to any specific implementation instructions contained within each IAN.

1.2 Whilst IANs shall be read in conjunction with the Qatar Highway Design Manual (QHDM), the Qatar Traffic Manual (QTM) and the Qatar Construction Specifications (QCS), and may incorporate amendments or additions to these documents, they are not official updates to the QHDM, QTM, QCS or any other standards.

1.3 Ashghal directs which IANs shall be applied to its projects on a case by case basis. Where it is agreed that the guidance contained within a particular IAN is not to be incorporated on a particular project (e.g. physical constraints make implementation prohibitive in terms of land use, cost impact or time delay), a departure from standard shall be applied for by the relevant Consultant / Contractor.

1.4 IANs are generally based on international standards and industry best practice and may include modifications to such standards in order to suit Qatar conditions. Their purpose is to fill gaps in existing Qatar standards where relevant guidance is missing and/or provide higher standards in line with current, international best practice.

1.5 The IANs specify Ashghal’s requirements in the interim until such time as the current Qatar standards (such as QHDM, QTM, etc.) are updated. These requirements may be incorporated into future updates of the QHDM, QTM or QCS, however this cannot be guaranteed. Therefore, third parties who are not engaged on Ashghal projects make use of Ashghal IANs at their own risk.

1.6 All IANs are owned, controlled and updated as necessary by Ashghal. All technical queries relating to IANs should be directed to Ashghal’s Manager of the Design Department, Infrastructure Affairs.

1. Glossary of Terms

BICYCLE ‐ A pedal‐powered vehicle upon which the human operator sits. The term “bicycle” for this publication includes three and four‐wheeled human‐powered vehicles, but not tricycles for children. BICYCLE FACILITIES ‐ A general term denoting improvements and provisions to accommodate or encourage bicycling, including parking and storage facilities, and shared roadways specifically designated for bicycle use. BICYCLE LANE or BIKE LANE ‐ A portion of a roadway which has been designated by pavement markings and, if used, signs, for the preferential or exclusive use of bicyclists. ON-STREET BIKE LANE – A dedicated cycle facility using the same road surface and general motorised traffic. This may be facility distinguished from the main motorised traffic by line-marking or different surface colouring. SHARED USE PATH – A route that is unsegregated facility used by more than one type of non-motorised, for example pedestrians and cyclists.

2. Introduction

2.1 Purpose

All Expressway Projects must provide for pedestrians and bicycles on all the 2.1.1

roads within the limits of works including approaches to ramp terminals

(including at-grade or grade separated facilities).

The report shall be considered as an interim design guide for the 2.1.2

a. On-Street Bike Lane

b. Shared Use Path

c. Shared Cycle Track and Pedestrian Path

Ministry of Municipal Affairs and Urban Planning (MMUP) is updating the 2.1.3

Qatar Highway Design Manual (QHDM) in which the design guidelines,

treatments, pavement design method, material selection and design parameters

are expected to be described in detail which will supersede this document.

This guide provides information on how to accommodate and design bicycle 2.1.4

tracks within the scope of relevant Ashghal infrastructure projects. Sufficient

flexibility is permitted to encourage designs that are sensitive to local context

and incorporate the needs of bicyclists, pedestrians and motorists. This guide is

not a Planning Guide. For locations and types of Bicycle Facilities, users are to

follow the recommendations of the Transport Master Plan Qatar (TMPQ) and

individual Project’s Requirements.

Consideration for the bicycle facility should take into account access, 2.1.5

connectively, safety and suitability. In order to provide an enjoyable alternative

transport mode.

2.2 Transport Master Plan Qatar - Bicycle Master Plan Objectives

The objectives of the TMPQ include encouraging improved mobility options 2.2.1

and more sustainable transportation choices such as public transit, walking and

bicycling.

Two goals are provided for the Qatar National Bicycle Master Plan. 2.2.2a. Goal 1: Increase Bicycle Use

b. Goal 2: Improve Safety for Bicyclists

Together these two goals provide the framework for all of the recommended

activities of the Bicycle Master Plan, whether by new infrastructure or programs.

The Qatar National Bicycle Master Plan establishes a network of bicycle 2.2.3

facilities and set of programs to be completed over the next 10 to 20 years to

make Qatar the number one cycling community in the world. The Qatar

National Bicycle Network recommends bicycle facilities that provide access to

all areas of Greater Doha, linking to schools, parks, stadiums and future transit

Page 11: PWA IAN 011 Rev A1 - Cycleway Design Guidelines

Ashghal – Cycleway Design Guidelines

PWA IAN 011 Rev A1 Page 11 September 2013

stations, and extend beyond Doha to connect with all of Qatar’s major

community areas and destinations including Al Khor, Al Wakra and major

recreational sites like the protected habitat preserves.

2.3 Hierarchy of Design Documents

The design and construction of relevant Ashghal infrastructure projects shall 2.3.1

ensure that the latest standard, manual, publications and guidelines incorporate

the most recent amendments.

The following documents shall be read in the following order of priority: 2.3.2a. Acts of Parliament

b. Ashghal Interim Advice Notes

c. Qatar Urban Planning & Development Authority – Transport Master Plan Qatar

d. Qatar Design and Traffic Manuals, Specifications and Standards

e. British Cycle Infrastructure Design and TA90/05 - The Geometric Design of Pedestrian,

Cycle and Equestrian Routes

f. London Cycling Design Standards published by Transport for London (TfL)

g. AustRoads Guide to Road Design Part 6A

h. Other International Guidance Documents and Standards

PWA IAN 011 Rev A1 Page 12 September 2013

3. Cyclist Requirements

3.1 Principals

The bicycle facility shall be designed and constructed in consideration of 3.1.1

addressing the six basic bicycle requirements: a. space to ride

b. a smooth surface, free of debris

c. speed maintenance

d. appropriate sight lines to path surface and potential obstructions

e. connectivity

f. information

Vehicle operators (including bicyclists) on a two‐way road to travel on the right 3.1.2

side relative to their respective direction of travel. With only a few exceptions

(such as when bike lanes are provided in both directions on an otherwise one‐way street), bicyclists operating in the street ride with the flow of other traffic.

Similarly to other vehicular traffic, a bicyclist on a minor road (including 3.1.3

driveways and alleys) must yield to traffic on major roads. In this case yielding

means proceeding only when it is safe to do so while obeying all traffic control

devices.

Speed difference between bicycle and motor traffic should be evaluated and 3.1.4

consideration for full integration maybe acceptable where the speed differential

is less than 20km/h. Conversely when speed the differential is greater than

40km/h segregation of bicycles from motor vehicles is required.

3.2 Cyclists Operation Space and Clearances

Page 13: PWA IAN 011 Rev A1 - Cycleway Design Guidelines

Ashghal – Cycleway Design Guidelines

PWA IAN 011 Rev A1 Page 13 September 2013

Figure 3-1: Typical Bicycle Width and Clearance - Source NCHRP 15-37: 2010

The bicycle corridor shall cater for the preferred operating width (1.5m). In low 3.2.1

speed confined areas, an exception to use the minimum operating width (1.2m)

maybe granted

3.3 Surface Tolerances

Grooves i.e. narrow slot in the surface that could catch a bicycle wheel, such as 3.3.1

a gap between two concrete slabs. a. Perpendicular to travel maximum 20 mm

b. Parallel to travel maximum 12.5 mm

Steps i.e. ridges in the pavement, such as that which might exist between the 3.3.2

pavement and a concrete gutter or manhole cover. a. Perpendicular to travel maximum 18 mm

b. Parallel to travel maximum 9 mm

PWA IAN 011 Rev A1 Page 14 September 2013

4. Design Criteria for Bicycles

4.1 General

The principles of designing a path for bicycles are similar to those used in 4.1.1

designing roads in that it is essential that the path has an alignment and cross-

section to suit the function of the path and the speed and volume of traffic,

drainage that prevents inundation and debris from washing onto the surface, and

adjacent areas that are forgiving to errant bicycles that leave the path.

4.2 Design vehicle

The off-road and on road bicycle lanes must be designed to accommodate a 4.2.1

standard upright adult bicycle dimensions, as shown in Figure 4.1 and 4.2.

Figure 4-1: Typical Bicycle Length - Source NCHRP 15-37: 2010

Figure 4-2: Typical Bicycle Key Dimensions - Source NCHRP 15-37: 2010

4.3 Bicycle Operating and Design Speeds

Refer to TA 90/05 Chapter 2: Except as follows: 4.3.1

2.4 A base minimum design speed of 30 km/h shall apply along all portions of 4.3.2

the bicycle facility except where reduction in design speed can be justified.

Page 15: PWA IAN 011 Rev A1 - Cycleway Design Guidelines

Ashghal – Cycleway Design Guidelines

PWA IAN 011 Rev A1 Page 15 September 2013

Installation of "speed bumps" or other similar surface obstructions, intended to 4.3.3

cause bicyclists to slow down in advance of intersections or other geometric

constraints, may not be used without prior approval.

2.6, 2.7, 2.8 and 2.9 not applicable for Cycle Path Design 4.3.4

4.4 Visibility

Refer to TA 90/05 – Chapter 3: Supplemented as follows: 4.4.1

The following performance criteria may be used a basic design principals to be 4.4.2

adopted within the bicycle lanes.

Figure 4-3: Bicycle Performance Criteria – Source NCHRP 15-37: 2010

The stopping sight distances provided should enable a cyclist to stop for various 4.4.3

combinations of bicycle operating speeds and gradients.

The stopping sight distance to be used in the geometric design of paths should 4.4.4

be at least equal to that shown in Figure 4-4, and should be used: a. for intersection design

b. in designing the alignment of paths

c. in relation to the positioning of terminals and handrails, but these should be avoided if

possible

d. at entries to underpasses

e. locate landscaping in the field

f. otherwise as required to ensure the safety of path users.

Figure 4-4: Minimum stopping sight distance for various gradients- Source AASHTO (1991)

The above Figure 4-4 is based on a coefficient of friction of 0.25 and a 4.4.5

perception/reaction time of 2.5 seconds. The eye height of the cyclist is

assumed to be 1.4 m and the object height is assumed to be zero to recognise

any impediments to bicycle travel exist at pavement level (e.g. potholes or

stones).

3.4, 3.9 not applicable for Cycle Path Design 4.4.6

4.5 Horizontal Geometry

Refer to TA 90/05 – Chapter 4 4.5.1

Cycle Tracks shall provide a curvilinear alignment to achieve a visually 4.5.2

pleasing path for cyclists, where possible. Minimum curve radius shall not be

used to provide this curvilinear alignment

4.6 Vertical Geometry

Refer to TA 90/05 – Chapter 4 4.6.1

PWA IAN 011 Rev A1 Page 18 September 2013

4.7 Gradient

Refer to TA90/05 – Chapter 5: Supplemented as follows: 4.7.1

5.4 The maximum grade rate recommended for bike paths is 5%. It is desirable 4.7.2

that sustained grades be limited to 2%. It is most important that sharp horizontal

curves or fixed objects do not exist near the bottom of hills, particularly where

the approach gradient is steep (greater than 5%) and relatively straight. If a

curve must be provided at the bottom of a steep grade then consideration should

be given to providing additional path width, and a clear escape route or

recovery area adjacent to the outside of the curve.

Figure 4-6: Maximum Vertical Grade - Source AGRD 2010

In cases where gradients are in excess of 5% occur, for example, on the 4.7.3

approaches to grade-separated facilities (e.g. underpasses) and in these

situations the provision of widened paths or clear escape routes is not

Page 19: PWA IAN 011 Rev A1 - Cycleway Design Guidelines

Ashghal – Cycleway Design Guidelines

PWA IAN 011 Rev A1 Page 19 September 2013

practicable. In these cases adequate sight distance should be provided together

with appropriate delineation and warning signs.

5.7, 5.8 & 5.9 not applicable for Cycle Path Design 4.7.4

4.8 Crossfall

Refer to TA90/05– Chapter 6. 4.8.1

A straight 2% cross slope is recommended on tangent sections. The minimum 4.8.2

superelevation rate of 2% will be adequate for most conditions and will simplify

construction. Superelevation rates steeper than 5 percent should be avoided on

cycle tracks.

4.9 Cross-Section

Refer to TA90/05– Chapter 7. Except as follows 4.9.1

7.4, 7.10, 7.11, 7.12, 7.13, 7.14, 7.15 not applicable for Cycle Path Design 4.9.2

Table 7.3 shows desirable widths and acceptable ranges of width for bicycle 4.9.3

paths (i.e. exclusive use). The upper limit of the acceptable range in the table

should not discourage designers from providing a greater width where it is

needed (e.g. very high demand that may also result in overtaking in both

directions).

4.11 Crossfall and Drainage

Where necessary, catch basins with drains should be provided to carry 4.11.1

intercepted water across the path. Such ditches should be designed in such a

way that no undue obstacle is presented to bicyclists.

Culverts or bridges are necessary where a bike path crosses a drainage channel. 4.11.2

However, Irish crossings can also be considered. This should be discussed with

Ashghal’s Drainage Department.

4.12 Clearances

Refer to Section 4.9 Cross Section. 4.12.1

4.13 Bicycle Path Lighting

Depending on the location, average maintained horizontal illumination levels of 4.13.1

5 lux to 22 lux should be considered.

4.14 Bicycle Path Shading and Water Stations

Bicycle Track should be shaded by either adjacent Landscaping or Tensile 4.14.1

Shade Structures.

Water Stations and Rest Area should be provided along stretches of Cycle 4.14.2

Track. Exact locations are to be agreed with relevant authorities and local

Municipalities.

4.15 Urban and Landscaping Design

The pedestrian and bicycle design are to be sited to maximise public open 4.15.1

space, connectively (desire lines) and safety.

The design is to take into consideration best international practice urban design 4.15.2

/ streetscape technics, the future land use, and the travel experience.

Opportunities to create or enhance recreation facilities, improve access, and

general amenity for the community are to be maximised.

Seating, shading and other street furniture elements must be provided at 4.15.3

appropriate locations.

The form of the Pedestrian and Bicycle Footbridges are to follow best practice 4.15.4

for Aesthetics Design guidelines, creating a high amenity environment for all

users

5. Bicycle Path Intersection Treatments

5.1 General

Access should always be provided where paths cross local streets and arterial 5.1.1

roads. Accessibility should be improved further by connections to local roads.

An integrated shared use path/bicycle/pedestrian treatment should be developed 5.1.2

for each Local Road, where no connection with the main Doha Bicycle

Network is available. The treatments should extend between the limit of the

Works where they can be safely transitioned back into the existing provisions.

Bicycle treatments and crossings are to be included within the review scope of 5.1.3

all phases of the Road Safety Audit Process.

5.2 Intersections Treatments

Most auto/bicycle accidents occur at intersections. For this reason, bikeway 5.2.1

design at intersections should be accomplished in a manner that will minimise

confusion by motorists and bicyclists, and will permit both to operate in

accordance with the normal rules of the road.

Table 5-1 provides guidance for selection of appropriate crossing facilities to be 5.2.2

integrated within the bicycle design.

5.4 Crossings at Unsignalised Junctions

Stopping sight distance should be provided for drivers approaching the 5.4.1

intersection from the local road with clear sight lines to cyclists for turning

motorists from the major roads into the local road.

Kerb ramps on both sides of the road shall be provided with a suitable terminal 5.4.2

treatment.

At locations where bicycle or shared-paths cross a minor local intersecting 5.4.3

street. The local street shall: a. Provide appropriate signage and delineation to ensure motorists are aware of the

existence of the crossing and the priority that applies

b. Encourage safe and correct use by cyclists

c. Not impede the safely of motorists turning in from the major road

Paths should be aligned to intersect roads at approximately 90 degrees. 5.4.4

Unsignalised crossings of local streets may require cyclists to give way to road 5.4.5

traffic, where traffic volumes exceed 3000vpd or 4 numbers of lanes, a typical

refuge should be provided.

For Straight across crossing (Refer Figure 5.5), the crossing point should be 5.4.6

positioned to provide refuge for at least one car length between the crossing

point and mainline carriageway.
