中文摘要： 最佳地利用城市道路网络以保障公共汽车交通（本项目简称公交）优先和便捷出行，不仅是应对交通需求剧增、日益拥堵背景下的交通问题，还关系到城市的效率和社会公平性，其研究具有重要的理论意义与实践价值。本项目特别在剖析城市道路网络（路网）与城市空间结构及公交网络间互馈关系的基础上，解析各等级子路网中客流结构（公交客流与小汽车客流）与路网结构的平衡关系；利用公交网络的层次分划和分级优化结果等重新划分城市道路网络等级；在此基础上，构建包含各等级目标函数及全路网目标函数的城市等级性路网协同优化双层规划模型，上层为干道网、换乘中心站、支路网的整体优化模型，下层为公交车和小汽车的双模式交通平衡模型，并求解模型完成城市道路网络优化，进而提出公交优先为导向的城市道路网络的等级优化方法。研究成果将为城市道路网络规划方法提供新方向和新理论，促进公交优先，并提升路网的交通性能。

英文摘要： Optimal utilization of urban road network to guarantee bus priority and convenient travel is not only the way to deal with traffic problem under the background of surging traffic demand and increasing traffic congestion, but also important for urban efficiency and social justice. To study this problem is theoretically and practically significant. This project particularly analyzes matching relations of road network structure and passenger structure (bus passengers and car passengers), based on interaction analysis of urban road network and urban spatial structure as well as regular public transport network. Then, the initially graded and hierarchical optimized ones of regular public transport network are utilized to redefine urban road network hierarchy. Furthermore, bi-level programming model for hierarchical road network collaborative optimization is established with the objective functions of each hierarchical level and the whole network. The upper model is overall optimization of arterials, central transfer stations, and branches, while the lower one describes bimodal traffic equilibrium model for bus and car. Finally, the urban road network optimization is completed by solving the model. All of the investigations come to hierarchical optimization method for road network under the guidance of bus priority. This study will provide new direction and new theories for urban road network planning to promote bus priority and improve traffic performance of road network.
