When roadway designers mention driveways, they are usually referring to the area of the driveway near its connection with the main roadway.  The design of these driveway connections may seem rather insignificant in the overall scheme of things.  However, past studies have reported that between 10 and 20% of all urban roadway collisions are related to driveways.  Along urban arterial roadways, research has shown that the frequency of driveways affects both the crash rates and traffic flow quality.  Clearly, the design of driveways can affect safety, mobility, and trip quality.

During the NCHRP 15-35 research project, the research team synthesized findings from previous studies and conducted new field research to provide a basis for the recently-published Guide for the Geometric Design of Driveways.  This presentation explains some of these findings that have a practical application for roadway design engineers.
