The purpose of this research was to develop a methodology for determining commercial driveway spacing guidelines on arterial roads through an optimization of both safety (accident rate) and level of service (density). This project was developed due to the recognition that access control is one of the most important design elements that affect roadway safety and capacity on arterial roads. Data for the study were obtained at selected urban and suburban sites within Virginia. A regression analysis was performed to develop models that independently correlated the driveway spacing with the density and the accident rate. Once these two models were derived, they were used to develop guidelines for the driveway spacing on roadways with varying access classification.
