To supplement the ADA, a range of resources are available for designers on accessibility. These are listed below. For All Ages and Abilities (AAA) bikeways, designers should use a user-focused approach and consider a range of mobility needs. For each of the user groups shown below, designers should critically consider how each person may navigate the street design, using best practice resources to address issues and identify potential solutions in partnership with stakeholders. Whenever possible, designers should conduct field visits and targeted engagement with stakeholders to understand the specific needs of users with disabilities.
Planning bikeway cross sections with as much width as possible helps ensure they are accessible to people using a wide range of bikes, including adaptive bikes.
Additional research and guidance on accessibility will be provided in a future White Paper for Countywide Bikeways Implementation.
For guidance on accessibility requirements for shared-use paths, designers should refer to PROWAG, published by the U.S. Access Board. Chapter R3. Technical Requirements
and the Supplemental Notice on Shared Use Paths
are the most relevant to designers for shared use paths. PROWAG guidance on shared use paths includes detailed requirements on spaces that are meant to be shared with bicycles and pedestrians, to ensure they are accessible for people with disabilities. These details include:
- Continuous clear width required
- Grade and cross slope
- Doors, doorways, gates, and protruding objects
- Curb ramps and blended transitions
- Considerations for conflicts between shared use path users
Where parking stalls are marked or metered, PROWAG
outlines guidelines for designated on-street accessible parking per block perimeter (shown below). While designated parking is not required where spaces are not marked and metered, designers should consider the overall impact of the bikeway design on parking accessibility and consider providing designated spaces even where not required. Access to businesses and key destinations should guide the placement and design of accessible spaces. Figure 19 of the FHWA Separated Bike Lane Planning and Design Guide
includes design detail for accessible parking with separated bike lanes. Additional guidance from MassDOT, Chapter 5
shows alternative layouts for accessible parking at corners or mid-block locations. While PROWAG is not officially adopted, designers should take a proactive approach to providing curb access with bikeway projects.
The non-profit organization Walk SF published Getting to the Curb
, a guide on pedestrian and accessibility considerations for separated bike lanes, specifically those with parking-protected bike lanes. Getting to the Curb is a helpful resource to understand issues and opportunities for design that meets the needs of multiple users, including those with disabilities. Designers should coordinate with stakeholders and on interdisciplinary teams to review ADA parking designs.
