摘要
在建立车辆-移动台轨迹映射关系模型的基础上,通过微观交通仿真平台与移动通信仿真平台的有机结合进行数据交互与联立仿真,建立了基于移动通信数据的交通信息仿真系统。选取广深高速公路麻涌-望牛墩路段作为仿真路段,实现并验证了路网中车载移动台的移动通信仿真数据生成过程。实验结果表明,该系统能够有效模拟车载移动台在路网中运行的交通特性与无线通信特性,产生移动台定位与切换等通信数据,为进一步的交通信息提取研究提供可靠数据。
By developing a trajectory mapping model between vehicle and the corresponding mobile stations, data interaction and simultaneous simulation between the microscopic traffic simulation platform and the mobile communications platform are realized, and then a traffic information simulation system is constructed based on mobile communications data. By choosing the Mayong-Wangniudun Section on Guangzhou-Shenzhen Freeway as the simulation road section, the simulation data generating process of mobile communication is verified. Experiments show that the system can effectively simulate mobile sta- tions traveling on the traffic network with vehicle characteristic and wireless communication features, also produce the location and handover data of the mobile stations, and provide reliable data for the research of traffic information extraction
