摘　　要：为了提高快速路匝道与关联交叉口运行效率,以快速路-交叉口协调控制影响因素为关键,建立基于交通状态指数、匝道入口影响因子的匝道与关联交叉口协调控制模型。以实际区域进行仿真验证。结果显示,模型能够明显改善系统运行情况,匝道总通过交通量增加8.7%,交叉口延误降低11%。In order to improve the operating efficiency of expressway ramps and associated intersections,taking the coordination control factors of expressway and intersection as the key,the coordination control model of the ramps and the associated interchanges based on the traffic state indexes and the ramp entrance influence factors is established to carry out the simulation verification of the actual areas.The result shows that the model can significantly improve the operation of the system.The total traffic volume on the ramp is increased by 8.7%,and the delay at the intersection is reduced by 11%.
