Abstract: In order to solve the problem that vehicles may hit the coming object on the road around a mountain，we put forward the system for mountain roads anti-collision and monitoring in targeted poverty alleviation area based on LBS． Android software is used to simulation the Internet + terminal for pedestrians and vehicles and Baidu Trace service is used as the main background for testing the availability of the system． This system is suitable for anti-collision monitoring on the winding mountain road traffic in targeted poverty alleviation area． It can calculate the location of dynamic vehicle or pedestrians that are out of the anti-collision safe distance and realize a global visualization so that pedestrians and vehicles in the narrow winding road can prepare for whistle or avoiding in advance relying on various moving trajectory and motion trial data forms from the background of Baidu Trace and make analyses for traffic monitoring and warning． The experiment result shows that the system is effective． Its alarm can reduce the probability of collision on the road around a mountain．
