Abstract:  In order to solve the problem of locating exclusive bus lane in the signal road network, this paper presents a combinatorial optimization model of exclusive bus lane location and transit signal priority design. The problem is summarized as a bilevel optimization structure. The upperlevel of the proposed model is designed to solve the integrated design and operation of exclusive bus lane location, lane functional allocation and passive bus priority design with an objective of minimizing the total travel time by car and bus. The lowerlevel of the proposed model is a location model of car users and bus users to minimize the generalized travel cost. A genetic algorithm is developed to solve the proposed model. Numerical analyses have demonstrated the validness of the proposed model. The results also show that the integrated optimization design approach of exclusive bus lane and transit signal priority is preferable to a simply optimizing approach of exclusive bus lane location. And the scientific construction of exclusive bus lane and transit signal priority can maximize the contribution of transit priority strategies to the efficiency of the entire multimodal transportation systems.
