中文摘要： 为实现高速公路通道的协调控制，本项目完成了以下研究工作：1）基于累积前景理论构建了不确定条件下的多目标多路径选择模型。2）考虑诱导服从率对高速公路、并行道路交通流的影响，建立了高速公路主线限速-匝道控制-诱导宏观交通流模型；考虑我国混合交通的实际，构建了多用户类动态配流博弈模型，这些模型有效地描述了交通流诱导与控制的关联关系。3）构建了兼顾公平与效率的高速公路入口匝道协调控制模型；结合基于规则与基于优化的自适应控制设计了一种公交优先控制方法。 4）设计了基于模糊聚类的交通控制子区动态划分方法；将分层递阶控制引入高速公路通道控制中，分别建立了高速公路通道各子系统内部、子系统间的协调控制器。5）创建高速公路通道网格体系，提出了快速求解协调控制问题的主从式并行求解算法。6）将复杂网络引入交通网络研究中，构建了高速公路路网演化模型、基于级联失效的路网节点重要度计算模型。 项目发表论文13篇，出版专著1部，申请专利1项，获中国公路学会科学技术二等奖1项。 出行需求的显著增加，交通缓堵越来越被重视，项目成果对高速公路通道交通组织具有重要指导意义，应用前景广阔。

英文摘要： In order to coordinately control freeway corridor, the following researches are finished: 1) Multi-criteria multi-route choice model under uncertainty is built based on the cumulative prospect theory. 2) Considering the impacts of the guidance obedience rate, a macroscopic traffic flow model on speed limit- ramp control-guidance is established. At the same time, a multi-class analytical game model on dynamic traffic assignment is devised taking into account the mixed traffic in China. These models effectively describe the relationship between traffic flow guidance and control. 3) The multi-ramp coordination control based on efficiency and equity is set up while the bus priority adaptive control method combined with rule-based and optimization-based is designed. 4) Dynamic division of control sub-area based on fuzzy clustering is suggested. Moreover, the hierarchical control is introduced into freeway corridor control to realize the integration design subsystems and coordination control among subsystems. 5) The freeway corridor grid and master-slave parallel algorithm is created to fast solving the coordination control model. 6) The freeway network evolution model is studied based on complex network theory while the node importance calculation model on traffic network is constructed using cascading failure. Through this project, 13 papers, one monograph, and one patent is published, a second prize of Institute of Science and Technology of China Highway is granted. With the significant increase of travel demand and more and more attention to traffic jams, freeway corridor traffic organization is more and more important, so these research results can be broadly applied.
