This document became the first national guide focused specifically on driveway design since the publication of AASHTOs 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. Detailed guidance is provided for all facets of driveway design, including the driveway itself, driveway-sidewalk intersections, driveway-roadway intersections, traffic control, and specific accommodations for all types of road users. The authors present six main considerations for driveway design, including maintaining or improving the safety and operations of the roadway, providing a safe entrance and exit for all users, providing adequate sight distance for all users, incorporating ADA requirements into all design aspects, supporting the requirements of public transportation when present, and integrating any existing bicycle lanes and pedestrian paths.
