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 extention, 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 bus-preemption. Under both with and without Automatic Vehicle Location environments, both developed models yield quite promising results.
