摘　　要：首先提出了基于车载自组织网络技术的车路协同原型系统(IVICS),并通过二次开发,利用交通仿真软件Paramics进行大规模路网搭建、动态信号控制,以及微观交通行为的模拟;同时,采用网络仿真工具NS2对车载网络进行细粒度无线通信过程的模拟,并通过trace文件,分析得到网络通信的带宽、延迟、传输跳数、丢包率等性能参数;此外,结合数据库技术,实现了交通仿真模块与通信仿真模块间的数据传递与共享,构建了车路协同一体化仿真系统,可以完成大规模城市路网中车辆自组织网络的通信仿真与分析,为车路协同系统的实际部署提供原型验证方案。A prototype of IVICS based on vehicular ad-hoc network was put forward.By reprogramming,the modeling of large-scale road network,dynamic signal control and microscopic driving behaviors were realized by using Paramics.Meanwhile,communication in vehicular ad hoc network with small granularity was emulated by using NS2.Bandwidth,delay,transmission hops,packet loss rate and other performance parameters of wireless communication were extracted by analyzing trace files.Data between traffic simulation module and communication emulation module were transferred and shared by using database technology to construct an IVICS.Such integration platform can realize large-scale simulation and analysis of vehicular ad hoc network communication in urban traffic to provide an effective scheme for IVICS verification.
