Channelization Guidelines to Accommodate Longer and Wider Trucks at At-Grade Intersections

摘要

The report addresses issues concerning the design of at-grade intersections to accommodate the turning characteristics of the various longer and wider truck configurations that were introduced into the traffic stream by 1982 Federal and State legislation. The objectives of the research were to complete a literature review of research concerning truck sizes, turning characteristics, and channelization; determine encroachment and swept path width for various combinations of design vehicle, curb radii, and degree of turn; and develop guidelines for design, operation, and channelization of at-grade intersections to accommodate these larger vehicles.
