高速公路收费站微观交通仿真系统设计

Design of Microscopic traffic stimulation system for highway toll station

通过对高速公路收费站处的微观交通仿真技术及基本微观交通仿真模型的研究,构建高速公路微观交通仿真系统,以期为今后对高速公路收费站处的交通组织研究提供帮助。基于中国学者对车辆微观仿真模型的研究及部分合理性推导,设计针对高速公路收费站附近区域交通流特性的车辆仿真系统,系统由道路设施模型、车辆生成模型、车辆跟驰模型、判断型车道变换模型、强制型车道变换模型、停车模型和重启动模型组成。系统在广州南沙港快速线仑头收费站进行初步模拟测试,测试结果显示,排队长度校核指标误差在10%以内,初步验证了系统的实用性。

This paper studies the highway toll of microscopic traffic simulation technology and the basic microscopic traffic simulation model, and then constructs a traffic simulation system, for which the system can offer some help for future research. Based on the micro-simulation model of vehicle and partially rational deduction,it designs a vehicle simulation system especially for the traffic flow characteristics of the area near the highway toll. The system is composed of road infrastructure model, vehicle generation model, car following model, determine-type lane change model, mandatory lane change model, parking model and restarting model. This system has performed a preliminary simulation test at Luntou toll station of Guangzhou Nansha Fast Line,the result of which exposes that the queue length error is within 10% and the system is initially proved to be practical.
