Improving Transportation Network Efficiency Through Implementation of Transit-Supportive Roadway Strategies

TRB’s Transit Cooperative Research Program (TCRP) Web-Only Document 66: Improving Transportation Network Efficiency Through Implementation of Transit-Supportive Roadway Strategies documents the research methodology used to develop TCRP Report 183: A Guidebook on Transit-Supportive Roadway Strategies. The web-only document provides detailed information on when these transit preferential treatments are applied and how they are designed.

TCRP Report 183 provides guidance for transit and roadway agency staff seeking to improve bus speed and reliability on surface streets while addressing the needs of other roadway users, including motorists, bicyclists, and pedestrians.

The guidebook identifies consistent and uniform strategies to help improve transportation network efficiency to reduce delay and improve reliability for transit operations on roadways; and includes decision-making guidance for operational planning and functional design of transit/traffic operations on roads that provides information on warrants, costs, and impacts of strategies.
