基于Google Earth的车辆防碰撞虚拟仿真系统

Virtual Driving System Based on Google Earth

车载自组织网络(VANET)是近年来智能交通领域的研究热点之一。在VANET网络中,智能车辆通过交互共享道路环境信息,可提高交通安全水平。在现实环境中进行大规模的车载自组织网络实验,在经济性和可行性上都具有较大困难。在SUMO交通仿真基础上开发出车辆防碰撞虚拟仿真系统,通过Google Street Map获取真实道路环境(如路网、楼宇、植被等),并结合GEMV2软件对智能车辆在真实道路环境下的无线通讯链路质量进行评估,实现了虚拟行车交通流与车辆间无线通讯质量评估两位一体的模拟仿真,增强了车辆对周围道路交通环境的综合感知能力。

Vehicle ad hoc networks is one of the research hot spots in the field of intelligent transportation in recent years.In reality,it is difficult to conduct large-scale experiments of vehicle ad hoc networks due to the limitation of economy and availability.Based on SUMO traffic simulation,we develop a virtual driving system which uses GEMV2 to evaluate the communication links between vehicles and builds up the simulation system which combines virtual driving with communication quality evaluation.
