ANALYTIC AND SIMULATION STUDIES OF FACTORS THAT INFLUENCE BUS-SIGNAL-PRIORITY STRATEGIES (ABRIDGMENT)

Research intended to identify conditions under which the greatest benefits to transit operations can be realized by implementing a bus-signal-priority strategy is described. Two techniques are presented for studying the problem. An analytic model was developed to compare the performance of bus systems operating with and without bus signal preemption. Studies were undertaken to examine the effects and interrelations of several factors in terms of bus operations. These factors include signal density, traffic volume, maximum signal-preemption length, passenger volume, bus headways, signal split and cycle length, station location, and exclusive right-of-way for buses. Insights from the study pertaining to each of these factors are described. In addition, the Federal Highway Administration's network flow simulation (NETSIM) model was modified to incorporate a bus-signal-preemption strategy. Simulation studies produced results that confirmed some of the insights provided by the analytical model and yielded additional insights. (Author)
