To explore the advantage of integrating bus-preemption with adaptive signal control, this study has produced two integrated models for adaptive bus-preemption control in the absence and presence of Automatic Vehicle Location systems. Instead of using prespecified strategies, such as phase extension, phase early start, and/or special bus phase, the proposed models make a preemption decision based on a performance index which includes vehicle delay, bus schedule delay, and passenger delay. This study also contains an extensive simulation evaluation with respect to the integration of adaptive control with preemption. Under both with and without Automatic Vehicle Location environments, both developed models yield quite promising results.
