Problems solved by technology

[0005] The existing method is to use the traffic police to rush to the congested place, and then manually guide them. However, this method requires a lot of manpower to direct, and the efficiency is not high. Understand, flocking to the congested road section all the time, leading to the deterioration of the congestion situation, resulting in secondary congestion

Abstract

The invention discloses a method for vehicle road guidance and evacuation based on cloud computing. The processing module, communication module, and storage module for storing data in the cloud server, the vehicles and traffic lights are all connected to the cloud server by communication, and all calculations are concentrated in the cloud server, and the vehicle does not need to perform any calculations, expanding the scope of applicable vehicles. Real-time position monitoring and route monitoring can be carried out on the vehicle, and the operation status of the vehicle can be grasped in time. It can accurately judge the location and road section of congestion, and notify the traffic police in time. Timely control the congestion situation by controlling traffic lights to prevent deterioration, and conduct orderly and accurate guidance for vehicles to evacuate after the situation is fully controlled.

Description

technical field [0001] The invention relates to a vehicle evacuation method, in particular to a cloud computing-based vehicle road guidance evacuation method. Background technique [0002] The so-called traffic congestion refers to that during a certain period of time, due to the increase in traffic demand, when the total traffic flow through a certain road section or intersection in the road is greater than the traffic capacity of the road (the traffic capacity of the road section or intersection), resulting in The traffic flow on the road cannot go smoothly, and more than part of the traffic flow stays on the road (road section or intersection). Due to the unsmooth traffic, vehicles travel slowly on the road, and the most direct impact is to increase the travel time and cost of residents. The increase in travel costs not only wastes time, but most importantly reduces work efficiency. [0003] Among them, sporadic congestion is mostly the sudden occurrence of traffic even...
