Method for automatically determining rescue path of expressway network

Abstract

The invention discloses a method for automatically determining a rescue path of an expressway network. The method comprises the following steps of: 1, after a traffic accident, acquiring information of an accident site, information of peripheral emergency rescue points and information of a road network; 2, searching a path which has the shortest distance from a peripheral rescue point to an accident point and serves as an initial backup rescue path from the expressway network according to the position of the accident point and the position of the peripheral rescue point; and 3, determining a traffic stream direction influenced by the traffic accident according to lane occupied positions and traffic stream directions of the occupied lanes on the accident site, and acquiring a road condition of the accident site, the number of jammed lanes of the accident site and the position of the accident point. By the method, a rescue path decision scheme in the expressway network of emergency resources can be generated automatically, so that the emergency resources can be transported to the accident site immediately, the emergency rescue efficiency can be improved, and casualties and property loss can be reduced.

Description

technical field [0001] The present invention relates to the creation of a highway network through computer automatic control in consideration of factors such as the road network structure of the highway network, road section traffic flow conditions, weather conditions, etc., combined with traffic accident rescue demand information and surrounding emergency resource reserve information The types, quantities and routes of resources that need to be transported to the rescue points of emergency resources to ensure timely and reliable transportation of emergency resources, provide resource guarantee for emergency rescue of traffic accidents on the expressway network, improve the efficiency of emergency rescue of traffic accidents, and reduce accidents Casualties and property damage. It belongs to the field of emergency management of road traffic. Background technique [0002] With the rapid development of our country's economy, in order to meet the needs of urban economic and so...

Problems solved by technology

But the actual situation is that when a traffic accident causes congestion, some social vehicles will drive into the emergency passage for their own interests, causing congestion of the emergency passage, and resulting in the impassability of emergency resources

Because the traditional method of selecting the shortest rescue path does not consider the impact of traffic accidents on traffic, it is easy to cause emergency resources to not be transported to the rescue site in time, which affects the rescue work of traffic accidents.
