A Path Induction Method Based on Feedback Mechanism

Abstract

The invention discloses a route induction method based on a feedback mechanism, which belongs to the field of traffic management and control. The route guidance method based on the feedback mechanism obtains the basic information data of the road and the operation information data of the vehicle in real time through the vehicle-road coordination technology, and generates a real-time vehicle guidance route by analyzing and processing the traffic data. The method includes: defining the route guidance control center, the urban road network, and the investigation behavior of vehicle traffic starting and ending points; proposing three different route guidance schemes, and selecting the appropriate route guidance scheme according to different traffic operation conditions; calculating the traffic impedance of the road section; calculating the intersection The traffic impedance at the entrance; choose the route with the least traffic impedance to induce vehicles to enter. The technical scheme of the invention eliminates the delay of traffic information, can provide real-time traffic operation status of the road, and provide road users with guidance information for choosing the optimal route.

Description

technical field [0001] The invention relates to the field of traffic management and control, and more specifically relates to a route induction method based on a feedback mechanism. Background technique [0002] The Intelligent Vehicle Infrastructure Cooperative System is IVICS (Intelligent Vehicle Infrastructure Cooperative Systems), referred to as the Vehicle Infrastructure Cooperative System. It is mainly through multidisciplinary interdisciplinary integration and advanced technical means such as wireless communication and sensor detection to realize the comprehensive perception of information on people, vehicles and roads, as well as the intelligent coordination between vehicles and infrastructure, and between vehicles and vehicles. In order to achieve the goal of optimizing and utilizing system resources, improving road traffic safety and efficiency, and alleviating road traffic congestion, the essence of vehicle-road coordination is to match the control command with th...
