英文摘要: Facing the demand of solving the efficiency and reliability problems which exist in the expending exclusive bus lane system and bus rapid transit system in China cities, this study focus on developing integrated optimization approaches based on the analysis of limitations of separate optimization of transit signal priority strategies and bus operating strategies. Three main parts are included in this research. In the first part, the interaction between transit signal priority control and operation control were analyzed. Several methods including theoretical analysis, simulation and data analysis were used to reveal the co-relationship in terms of the objectives, vehicle status variation, and characteristics of traffic flow. In the second part, the offline integrated optimization models of transit signal priority control and operation control were formulated and analyzed. Some critical issues including dividing of control unit, integrated optimization of bus frequency, location of bus stops and signal timings, lane-based signal timings optimization, pedestrian crosswalk control and phase sequence optimization were addressed in this part. In the last part, the models for online integrated optimization of transit signal priority control and operation control are presented, including coordinated model of bus holding time and signal timings, intersection-group based bus status deviation recovery models, sequencing model for multiple priority requests, and transit signal priority control strategy for intersection with far side bus stop, and integrated optimization of dynamic bus speed and signal timings in a connected vehicle environment. This research is a new expedition of transit signal priority control and operation control strategies, and lays a foundation for developing of advanced traffic control system and transit operation system. The proposed methods also can contribute to improve the reliability, efficiency and level of service of transit system.
