摘要: 城市快速路是城市交通的主动脉,承担着城市大部分交通量,良好的快速路控制策略能有效缓解道路拥堵。本文借助改进的宏观交通流模型,采用Visual Basic面向对象语言,开发城市快速路的控制仿真系统。运用该仿真系统对一个包含两起点两终点的快速路段进行仿真,模拟采用ALINEA策略和不采用控制的快速路交通运行状态。仿真结果表明,对入口匝道实施ALINEA控制后,高峰时刻主线流量增加约150veh/h,入口匝道与主线汇合区速度提高约10km/h,说明ALINEA控制策略能有效缓解快速路拥堵。

Abstract: The freeway takes large parts of city’s traffic flow. Good traffic managements and control strategies can ease traffic congestion effectively. This paper uses Visual Basic to develop a simulation program based on macroscopic dynamic network model METANET and ALINEA control model. Then the program is used to simulate a network with two origins and two destinations. The simulation results show that speed of freeway adds about 10 km/h and the capacity of freeway with ALINEA control adds about 150 veh/h. The ALINEA control can relieve traffic congestion effectively.

Key words: freeway, macroscopic traffic model, ALINEA, traffic simulation
