DEVELOPMENT AND USE OF A COMPUTER SIMULATION MODEL FOR THE EVALUATION OF DESIGN AND CONTROL ALTERNATIVES FOR INTERSECTIONS OF MINOR ROADS WITH MULTI-LANE RURAL HIGHWAYS: MODEL APPLICATION

This part of the simulation phase of the study dealt with the use of the validated model in evaluating design and control alternatives to improve traffic safety and operation at intersections of minor roads with multi-lane rural highways. Different design and operational countermeasures for stop controlled as well as for signalized intersections were evaluated by a group of simulation experiments. For stop controlled intersections, the evaluated countermeasures were: intersection median width, median opening, median control, intersection width, approach grades, advance warning systems, and speed enforcement. As for signalized intersections, the evaluated countermeasures were: signal control type, signal timings, number of signal phases, advance warning systems, speed enforcement, amber and all-red phase durations, and detector setback from the intersection. Left-turn accidents caused by a shadow factor effect were also investigated.
