BUS-PREEMPTION UNDER ADAPTIVE SIGNAL CONTROL ENVIRONMENTS

To explore the advantages of integrating bus preemption and adaptive signal control, an integrated model for adaptive bus-preemption control in the absence of automated vehicle location systems was developed. In the proposed system, unconditional priority is not given to buses over passenger cars. Instead of using pre-specified strategies such as phase extension, phase early start, or special bus phase, preemption decision is based on a performance index, which includes vehicle delay, bus schedule delay, and passenger delay. An extensive simulation evaluation with respect to the integration of adaptive control with preemption is also presented. The developed model displays promising results.
