INTERSECTION DESIGN CONSIDERATIONS TO ACCOMMODATE LARGE TRUCKS

The geometric and operational considerations of large trucks at intersections are addressed. The discussion summarizes the related findings of an FHWA study of truck characteristics for use in highway design and operations. Also cited are the implications of the Turner truck proposal, comparisons with Canadian Interprovincial trucks, and the preliminary results of recent research on AASHTO intersection sight distance procedures. A brief review of channelization requirements of large trucks, the effects large trucks have on intersection capacity and traffic signalization, and advance warning sign placement considering truck stopping distance and deceleration rates is provided.
