A simulation model of a 2-lane rural road. Paper prepared for the 47th Annual Meeting of the Highway Research Board HRB, Washington, D.C., January 1968.

A simulation model has been developed to evaluate traffic flow and safety benefits arising from use of remedial devices which would aid passing manoeuvres on 2-lane rural roads. Initially the effects of no-passing zone configurations due to road geometry and knowledge of oncoming car speed on tangents were investigated. Results show that no-passing zones cause a marked decrease in throughput, while oncoming car speed information appears to have a beneficial effect on safety.
