    摘要:

    为优化过江通道入口匝道交通组织,运用双层规划模型计算最佳入口匝道分流比例,上层规划目标为路网匹配性最大,并采用粒子群算法求解;下层模型为用户均衡模型,采用F-W算法求解。以长沙市湘府路大桥为例,从行程时间、畅通性、路段交通状态和交叉口交通状态评价过江通道与疏解路网的匹配性,给出不同交通需求下的匝道交通分流方案。研究结果表明:基于匹配性最优的过江通道入口匝道控制方法可以有效缓解局部拥堵,可操作性强。

    Abstract:

    In order to optimize the traffic organization of the cross-river channel at entrance ramp,the two-layer planning model was used to calculate the optimal diversion ratio of the entrance ramp. The upper planning target was the road network with the greatest matching,and particle group algorithm was used to solve. The lower model was the user equilibrium model,which was solved by F-W algorithm. Taking the Xiangfu Road Bridge in Changsha City as an example,The travel time, smoothness,road traffic state and intersection traffic state were utilized to evaluated the matching between the river-crossing channel and the road network. The traffic diversion scheme of the ramp under different traffic needs is released. The result shows the ramp control method for river crossing channel based on optimal matching can effectively alleviate local congestion,that has has strong operability.
