PURPOSE AND SCOPE

This guide provides a single, comprehensive reference of current practice in the geometric design of transit facilities on streets and highways. The facilities covered include:

• Local buses, express buses, and bus rapid transit operating in mixed traffic, bus lanes, and highoccupancy vehicle (HOV) lanes, and bus-only roads within street and freeway environments; and

• Streetcars and LRT running in mixed traffic and transit lanes, and within medians along arterial roadways.

These guidelines are based on a review of relevant AASHTO, TRB, and ITE documents, and of design reports provided by various transit agencies. They incorporate findings from targeted investigations conducted specifically to fill voids in the assembled information.
