NCHRP Report 659: Guide for the Geometric Design of Driveways

Click here if you liked this information

This document became the first national guide focused specifically on driveway design since the publication of AASHTO’s An Informational Guide for Preparing Private Driveway Regulations for Major Highways in 1959. Since 1959, the transportation system and its needs have changed drastically, and this report addresses the need for a comprehensive driveway design guide that accounts for vehicles, pedestrians, and bicyclists. The report identifies more than 90 design elements that directly or indirectly affect the geometric design of a driveway or access point.
