Simulation of corridor traffic (SCOT), a recently developed computer model that simulates traffic flow within a specified traffic system, has been used to predict the effect on bus service and general traffic performance of implementing candidate bus priority strategies. Numerical values of standard traffic performance measures were determined from computation of network vehicle trajectories. SCOT was calibrated to current peak-hour traffic conditions within an urban street grid representative of the central business district of Minneapolis. Data from city agencies were used in conjunction with field experiments to verify SCOT simulations. Various bus priority strategies designed to increase bus speeds by providing bus-only lanes were evaluated. The significant elements in bus travel time were shown to be frequency of station stops and red light signals. Further studies planned include identifying optimum bus station locations, developing bus progressive traffic signal timings, and evaluating various bus preemption of traffic signal strategies. Demonstration projects are under consideration to evaluate the simulation technique as a transit operations tool.
