Abstract:The use of traditional system to plan traffic route is poor adaptability under the condition of traffic congestion or external interference. Therefore, a traffic transportation route planning system based on fuzzy adaptive PID control is designed. The fuzzy control unit is introduced into the traditional PID system. In order to improve the adaptive ability of the control unit, the parameters of the adaptive PID system are fuzzy processing. The control variables are clearly defined through complex fuzzy reasoning and data interaction. Finally, the intersection path of the intersection is optimized by the VB language. The transport route is more clear and controllable. Through a large number of simulation experiments, it has been proved that the proposed system can ensure that the vehicle does not deviate from the route and greatly reduces the deviation, which shows that the proposed system is more adaptable and can effectively control the vehicle deviation and more reliable.
