METHODOLOGY FOR SELECTION OF BUS PRIORITY SCHEMES

Total person travel time is a good measure of the effectiveness of a system. It incorporates delay and free flow operating speed, two factors used in determining the level of service of a roadway. The methodology developed in this report uses savings in total travel times, measured in person-hours, as a criteria for selection of a bus priority scheme. Two graphs have been developed as a general guideline for determining what bus and car volumes will produce a savings in delay by using a particular scheme. High occupancy vehicle strategies can be analyzed in a similar way. High-occupancy vehicles (hov) may include car pool vehicles, vans, and/or taxis. The volume of hov's will replace the volume of buses in the analysis and when the total person travel time is calculated the average vehicle occupancy of the hov's may be used to convert vehicle hours to person hours. Although this paper has been devoted to bus priority systems on city streets, the methodology can be applied to freeways as well with some minor changes. Intersection delay can be switched with delay incurred at the on and off ramps. Total person travel times can still be used to measure the effectiveness of a system. (a)
