Abstract:
Driveways are an important and growing component of highway transportation systems. They have grown in number and complexity as urbanized areas have expanded. This paper traces their development and identifies key geometric issues and elements. It presents the salient results of a comprehensive agency-practice survey and literature review. Finally, it suggests possible areas for further research. A key finding is to design driveways in a multi-modal context that provides for safe and convenient movement by motor vehicles, bicycles, and pedestrians.
