The roadway is the portion of the public ROW dedicated to vehicular travel (bicycles, cars, buses, trucks, and emergency vehicles). It may also include a median, and any space for on-road parking. The roadway design should accommodate travel by all modes while reinforcing the role of the street as a public space, and supporting community activities along the road edge and adjacent lands. Efforts to calm traffic and to narrow the roadway are also an increasing City priority in the Urban Area.
Provide facilities for cyclists along designated cycling routes.
Collector Roads serve as an important part of the City’s cycling network, allowing cyclists to travel within and between neighbourhoods without the need to use higher-speed and volume Arterial Roads. Accommodation of cyclists on Collector Roads throughout the Urban Area is therefore a key concern.
- Accommodate cyclists on Collector Roads in the Urban Area and Villages through the use of 4.25m shared lanes where a high level of cycling priority is planned in the Official Plan and/or Cycling Plan.
- Construct dedicated cycling lanes (1.5m to 1.8m in width) only in the few instances where on-road cycling routes are designated along Major Collector Roads in the Official Plan, where on road parking is not required, and where the available ROW permits. Otherwise, use shared lanes along those routes.
- Consider dedicated cycling lanes where a retrofit “road diet” (road narrowing) is being considered on a road with a wide (10.0m or greater) pavement width or where on-road parking is not required on one or both sides of the roadway.
- In locations where a cycle lane would be next to an on-road parking lane, the total width of both lanes should be 4.5m to provide adequate separation from door openings.
- Locate catch basins and maintenance-hole covers outside of the wheel path of cyclists. Use the City of Ottawa standard curb-face inlet wherever possible as a cyclist-friendly solution.
5.4.2 Travel Lanes
Collector Roads are intended to accommodate a broad range of vehicle types including buses, passenger vehicles, and trucks of various sizes, as well as cyclists. They are also intended to carry moderate volumes of traffic at relatively low speeds.
- In most cases two lanes (one per direction), plus turning lanes where warranted, should provide sufficient capacity for vehicular movement at moderate speeds. Where four vehicle lanes are necessary along designated Major Collector Roads due to higher traffic volumes, refer to the City’s Regional Road Corridor Design Guidelines as a design reference.
- Minimize vehicle lane widths, while considering safety and capacity requirements, to reduce the amount of asphalt, pedestrian crossing distances, and to dedicate as much of the ROW as possible to the road edge.
- Provide wider lanes in the range of 3.5 to 4.25m for roads with higher speeds and volumes and mix of traffic including trucks, buses and larger vehicles as well as cyclists. For Collectors in Villages and more-urban contexts, use narrower lanes ranging from 3.0 to 3.5m, with turning lanes at 3.0m.
- When reconstructing Collector Roads, reduce existing lane widths to the minimum appropriate widths, in favour of increasing space for pedestrians, cycling lanes (where appropriate) and road edge landscaping, to reduce infrastructure life cycle requirements.

Use Bump-outs at corners or at the middle of long blocks to define the parking lane and calm traffic.
5.4.3 On-Road Parking
Given the primary objective for Collector Roads to support adjacent neighbourhood functions, on-road parking should generally be provided to meet the needs of residents, visitors or customers of adjacent land uses. On-road parking can also provide for traffic calming of Collector Roads if used appropriately. However, provision of excessive space for on-road parking may result in situations where more parking is provided than is required. This leads to unnecessary pavement width, where space could be better used for road-edge functions such as landscaping, sidewalks, etc., or where the ROW width could be reduced.
- Provide on-road parking on roads with land uses that are directly accessible from the corridor. This will calm traffic, separate pedestrians from traffic, and promote corridor-oriented community activity.
- Provide bump-outs to define road segments with full time on-road parking. Bump-outs delineate vehicle lanes, calm traffic speeds, reduce pedestrian crossing distances, and to provide space for tree planting, street furniture, transit stops and bicycle parking between the vehicle lanes and the sidewalk.
- In road retrofits using bump-outs to create a parking lane, use paint striping along the parking lane to announce and delineate the new use of the road surface.
- In areas with lower parking demands, such as along natural areas or in lower density single detached housing areas, consider on-road parking on one side of the street only to reduce pavement width. Alternate the single parking lane from one side to the other along the street so that the benefits of additional landscaping can be shared among both sides.
- Plant trees in bump-out areas where appropriate. If not, construct the sub-grade to the same standard as under the road pavement to maintain the structural integrity of the roadway and reduce future maintenance or re-construction costs. This also allows the bump-out area to be easily converted to travel lanes or parking if ever appropriate.
- Construct on-road parking lanes 2.5m wide, with 2.25m acceptable in constrained areas or on lower speed/volume roads. Where a parking lane is used as a travel lane or turn lane during peak hours, it should be of a lane width appropriate to the street.
- Limit on-road parking in corridors with dedicated cycling lanes to reduce conflicts.

For higher activity Collector Roads with wider ROWs, there may be the need or desire for placement of a median between opposing traffic lanes. Medians may also be used to define a unique urban district or gateway area.
- Limit the use of medians to reduce the road corridor width. Use medians as a traffic control measure only after other measures are considered.
- Restrict the use of medians to locations at major intersections along the busiest Collector Roads to protect left turn lanes, or to control traffic turning movements at specific locations.
- Where used at intersections, design the median with a sufficient width (1.5m) for traffic signal infrastructure that may be required.
- Consider the use of wide landscaped medians for unique streets (such as “Green Streets”, see Section 8) or as entry points into distinctive neighbourhoods. Medians can accommodate landscaping and street light poles, and can be used to reduce the number of vehicle lanes during road retrofit projects. They can also spatially define wide road corridors and provide refuge areas for pedestrians and cyclists, especially where multi-use pathways or local streets intersect with Collector Roads.
- Select landscape materials for medians according to the guidelines for road edge landscaping.
- Construct medians with barrier curbs as opposed to mountable curbs, to prevent vehicle intrusion into the median area.
