TRB’s Transit Cooperative Research Program (TCRP) Report 95: Traveler Response to Transportation System Changes, Chapter 2 – HOV Facilities examines how travelers respond to high occupancy vehicle (HOV) applications. HOV facilities provide preferential treatment for transit, vanpools, carpools, and other designated vehicles by providing lanes and roadways reserved for their use. HOV and bus-only lanes in separate rights-of-way, on freeways and tollways, on ramps, and on arterials and city streets are among the approaches used for giving HOV priority over general traffic. The report does not cover busways primarily on their own alignment. This application is addressed in TCRP Report 95: Chapter 4 - Busways, BRT (Bus Rapid Transit), and Express Bus. This report is part of TCRP’s Traveler Response to Transportation System Changes Handbook series. The overarching objective of the Traveler Response to Transportation System Changes Handbook is to equip members of the transportation profession with a comprehensive, readily accessible, interpretive documentation of results and experience obtained across the United States and elsewhere from (1) different types of transportation system changes and policy actions and (2) alternative land use and site development design approaches.
