摘　　要：针对信控网络下的公交专用道选址问题,从宏观网络优化角度提出公交专用道选址和公交信号优先控制的组合优化模型.上层模型是以最小化路网用户总出行时间(包括小汽车用户和公交车用户)为目标的公交专用道网络布局、交叉口车道功能分配和被动公交优先控制策略组合设计决策;下层模型是在信控网络下以最小广义出行成本为目标的小汽车和公交车客流分配模型.提出了基于连续权重平均法的遗传算法求解该模型,并通过算例验证了该模型的有效性与实用性.算例结果表明:相比单一公交专用道选址方案,公交专用道布设方案和公交信号优先控制方案同步优化设计能够更大程度地发挥公交优先效益,对路网通行效率的改善效果更优.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 de sign. 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 function- al 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 optimi- zation 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.
