From page 11... ... 2-1 Pedestrians should be expected at most A.I.I.s., and the design should integrate their needs, starting at an early concept development stage and continuing throughout the design process. Pedestrians are vulnerable road users; their risk of death in a crash increases significantly with higher vehicle speed (2) Read the entire page →

Greater sidewalk widths are needed as volumes of pedestrians increase, and pedestrian facilities in urban areas tend to require more space than in lower volume areas. Read the entire page →
From page 13... ... Pedestrians 2-3 When designing for people with disabilities, it is important to design not just for the minimum requirements, but with consideration for the needs of all other users of the facility and their relative volumes. For example, while the minimum curb ramp width to meet accessibility requirements is 48 inches in proposed PROWAG, that width cannot accommodate large groups of people walking or accommodate bicyclists operating on a shared-use path.

Three primary categories of design principles for pedestrian facilities are discussed below: • Pedestrian Routing and Delay • Minimizing Conflicts with Motor Vehicles • Minimizing Conflicts with Bicycles Efforts should be made to include as many positive pedestrian features as possible in the given context and constraints.
