SIMPLIFIED ESTIMATORS FOR BENEFIT ASSESSMENT OF BUS PRIORITY SYSTEMS

Simulation studies indicate that a Bus Priority System (BPS) that guarantees a green traffic signal to buses approaching an instrumented intersection provides substantial benefits to buses with little detriment to other traffic. Simplified estimators that correlate well with many aspects of the simulation results provide a better understanding of the BPS process and a means of analyzing the effects of BPS in applications other than that simulated. A bus travel time estimator predicts values within 10 percent for local buses, although the accuracy is less for buses with less frequent stops. An intersection capacity estimator reflects how certain conditions lead to greatly increased travel times for other vehicles in the simulation network and how far-side bus stops are superior to near-side bus stops at short bus headways.
