可变车道是应急交通情况下疏散交通流的重要手段，我国道路交通管理者多凭借经验来确定车道的方向使用权，尚缺乏有效的理论和技术支持。 本项目应用有关复杂网络结构、搜索、同步的理论和方法，把针对大规模交通网络的可变车道问题分解为针对小模块的同步问题，具体内容如下：构建城市道路交通网路的模块强度模型，研究基于模块强度最大化的应急疏散区域划分方法，来确定实施可变车道操作的范围；探究城市道路交通网络Hub节点的辨识方法，凝聚基于Hub节点的模块堆，建立基于模块堆的可变车道模型，获取模块堆和Hub节点的期望状态，并以此为目标对Hub节点实施同步策略，以维护网络的稳定状态；最后从管理者和出行者的角度建立城市道路交通网络效率指标和连通性指标，用以分析可变车道方法对网络性能的影响。 项目预期成果将丰富复杂网络理论和城市交通管理规划理论，为城市交通管理部门对应急疏散区域实施可变车道提供理论依据。

Contraflow lane is important means of evacuation traffic flow in emergency conditions, many of traffic managers in our country determine the direction of the right to use of the lane with the experience,still lack of effective theory and technical support. Application of complex network structure, search, synchronization theory and method theory and method, contraflow lane problem for large-scale traffic network is decomposed into the synchronization control problem for small module, the specific contents are as follows: Build the module strength model of urban road traffic network, research on division method of the emergency evacuation zone based on maximum module strength to determine the scope of contraflow lane. Explore Hub nodes identification method of the urban road traffic network, agglomerate the module reactor based on Hub nodes, establish contraflow lane method based on the modular reactor,obtain the desired state of the modular reactor and Hub nodes to implement synchronization control for Hub nodes, and maintain the steady state of large-scale traffic network. Finally, set up efficiency index and connectivity index of urban road traffic network from the point of managers and travelers of view to analyze the impact of contraflow lane method on the performance of large-scale traffic network. The expected results of the project will enrich complex networks theory and urban traffic management planning theory, to provide a theoretical basis for urban traffic management department to implement contraflow lane in emergency evacuation area.
