A study to evaluate the effectiveness of two bus priority strategies using a validated traffic simulation program is described. The test network, which is located in the Central Business District of Minneapolis, Minnesota includes two major arterials, each with a contraflow bus lane. The first control strategy consists of a fixed-time traffic signal pattern generated by the SIGOP-II model, which is designed to minimize passenger-delay, rather than vehicle-delay. The second control strategy is a real-time policy which preempts the fixed-time control to provide preferential treatment for approaching bus vehicles. The simulated results for each strategy were compared with those reflecting the existing fixed-time signal control. This study indicated that, for this application, the reduction in delay for bus passengers as predicted by the simulation program provided by both strategies outweighted the additional delay experienced by passengers in private vehicles; the preemption strategy provided greater improvement in performance than did the other. The study also demonstrates that a validated simulation model is an effective tool for evaluating alternate design configurations prior to field demonstration. /Author/
