Abstract

The relatioships between safety and design for lane width, shoulder width, shoulder surface type, and accidents have been developed. The objective of this paper is to demonstrate how these and other relationships may be employed to obtain optimal design specifications for lane width, shoulder width, and shoulder surface type. A manual procedure is presented for basic design problems. As the complexity of the problem increases, some computerized optimization procedure, such as dynamic programming, is recommended.
