AASHTO TVF-1, Guide for Geometric Design of Transit Facilities on Highways and Streets, 1st Edition (2014), provides guidance for the geometric design of transit facilities on streets and highways. The guide opens with an introduction and chapters on planning and decision-making and on design parameters and controls for transit projects. Separate chapters address bus facilities on limited access highways and guidelines for bus facilities on streets and roadways. Additional chapters cover light rail and streetcar facilities on streets and pedestrian and bicycle access to transit facilities. The publication was developed under TCRP Project D-09 with a panel drawn from transit agencies and state departments of transportation. Designers and reviewers working on street and highway projects that accommodate buses, streetcars, and light rail can use the guide.
