Abstract

The invention discloses a route selection method and system based on road abnormal area evaluation. The method comprises that a traffic route model data storage module is initialized; physical sensors in vehicles acquire and transmit vehicle traveling data to a nearest traffic route information acquisition module which filters and integrates the data into hot spot (HSP) information data of a current road section; every once in a while, all traffic route information acquisition modules upload HSP information data of all road sections to an HSP processor; a processing module calculates impedance generated by each current road section of each HSP, collects and generates the impedance into traffic road model data and updates the data to the traffic route model data storage modules; optimal route selection modules calculate optimal routes after vehicles update and download the traffic road model data. By means of the route selection method and system, the route selection efficiency can be improved, traffic transportation pressure can be well relieved, traffic road resources are well distributed, and the traffic transportation capacity is improved.

Description

technical field [0001] The invention relates to the field of intelligent traffic control, in particular to a path selection method and system based on road abnormal area evaluation. Background technique [0002] Nowadays, the traffic volume is huge, the network is complex, and there are many choices of driving routes, and the safety and reliability of each route are not the same. At the same time, the vehicle has developed from a purely physical system to a more complex cyber physical system (CPS, Cyber ​​Physical System) that includes a variety of electronic components and control systems. CPS adopts cloud platform to realize traffic control and system management, and can effectively process massive data, so as to improve its own performance and security. With the construction of traffic cloud infrastructure, the on-board navigation system can take real-time traffic information into consideration when helping drivers choose the best route. [0003] Among many path selecti...
