Although parking is an important issue in transportation engineering and planning, little research has examined the use of new parking information technologies in rural communities. The Clemson University campus, in South Carolina, was used as a case study to determine the ability of roadside parking information systems to reduce delay, cut travel time, and manage changing volumes of cars. To examine these effects, a traffic simulation model of the campus was built, calibrated, and validated. The model used a dynamic assignment approach to capture the rerouting of vehicles in response to parking availability information for several key parking lots. It was found that use of roadside parking information systems, such as dynamic message signs, can reduce delay while not significantly affecting volumes, travel times, or speeds. The findings suggested that delay reduction was caused by a decrease in vehicle circulation time.
