Research for AASHTO Standing Committee on Highways. Task 296. Alignment of the Draft AASHTO Transit Guide with the AASHTO Green Book

The objectives of this research were to review the comments made during the balloting of the draft American Association of State Highway and Transportation Officials (AASHTO) Transit Guide and to revise the draft Guide appropriately to resolve those comments. The draft AASHTO Guide for Geometric Design of Transit Facilities on Highways and Streets is envisioned as a companion to the AASHTO Green Book, providing departments of transportation (DOTs), transit professionals, and design consultants with guidance specific to the proper incorporation of transit vehicles and facilities within the street environment. Transit vehicles in the guide include buses, streetcars, and light rail transit vehicles. The draft Transit Guide was developed through Transit Cooperative Research Project (TCRP) Project D-09, Transit Vehicles and Facilities on Streets and Highways. During the AASHTO balloting process, reviewers noted significant inconsistencies between the draft Guide and the AASHTO Green Book. Many states have not submitted ballots, perhaps owing to the length of the draft Guide. Satisfactory resolution of the comments is needed before another round of balloting is undertaken. The draft guide has been revised based on the balloting comments and delivered to AASHTO for their further handling.
