摘要
针对目前车载导航仪在导航时只能给出两个地点间的最短路径,却不能根据实时的交通状况和限行情况给出最合理的行驶路径的问题,采用地理信息系统(GIS)与通用分组无线服务(GPRS)技术,建立了由信息发布中心与车载终端组成的智能汽车导航系统模型,并给出了信息发布中心更新路况信息的方法和最优路径选择算法.实验结果表明导航系统能够根据当前的路况信息快速的给出最优的通行路径,合理的避开了拥堵路段和限行路段.
To solve the program that vehicle navigation currently can only give the shortest path between two locations in navigating but can not give the optimal path based on real-time traffic information,we present a model of intelligent vehicle navigation system that consists of vehicle terminal and information distribution center based on Geographical Information System(GIS) and General Packet Radio Service(GPRS),and put forward the method of updates real-time traffic information and optimal path algorithm.The results show that the vehicle navigation system can compute an optimal path based on real-time traffic information to avoid traffic congestion.
