PLANNING AND DESIGN OF PASSING LANES USING SIMULATION MODEL

This investigation of approximately 560 km (350 mi) of two-lane highways in Imperial, San Diego, and Riverside counties, California, is the basis for planning and preliminary design of passing lanes in difficult terrain in Southern California. The present paper gives reasons why passing lanes are necessary, such as extensive delays, driver frustration, and increased accidents. Video logs captured and documented highway conditions for planning and highway simulation purposes. The TRARR (traffic on rural roads) simulation model determined the impact of proposed passing lanes and turnouts on level of service. The use of the simulation model enabled planners to evaluate a range of passing lane alternatives for a broad range of traffic, vehicle, and driver characteristics. Following the investigation, 117 new passing lanes and four turnouts were recommended for the 560 km of State routes.
