Method for acquisition and treatment of road traffic accident data

Abstract

The road traffic accident information collection and processing method involves determining the implementation scope of traffic control, signal control, information induction and other rapid traffic handling measures according to the traffic accident information after the road traffic accident occurs, and calculating the traffic congestion caused by the traffic accident. The length L, the queue length coverage area is called the congestion range; combine the congestion range and the diversion path into the candidate area information; obtain the regional total travel time T2 after the traffic flow in the candidate area is redistributed; determine the regional total travel time change index λ=((T2-T1) / T1)×100%; within the scope of the candidate area, the rapid handling measures for traffic accidents should be taken; judge whether the search radius R is greater than or equal to 2000 meters, if so, each The information on the rapid handling measures of traffic accidents that should be taken within the scope of the candidate area is transmitted to the host computer of the traffic management department through the data transmission interface; otherwise, the search radius R is extended by 300 meters.

Description

technical field [0001] The present invention relates to determining the implementation scope of rapid traffic handling measures such as traffic control, signal control, and information guidance according to traffic accident information after road traffic accidents occur, so as to improve the implementation efficiency of various traffic handling measures and effectively alleviate accidents. The effect of on-site traffic pressure, reducing motor vehicle delays and avoiding further spread of traffic congestion. The utility model belongs to the field of urban road traffic control. Background technique [0002] With the development of my country's economy and society and the improvement of people's living standards, cars have gradually entered the family, and the number of urban car ownership has increased rapidly. What follows is the frequent occurrence of urban road traffic accidents, which not only cause casualties and property losses, but also easily lead to a decrease in th...

Problems solved by technology

At present, it is impossible to comprehensively apply various traffic disposal measures and maximize the effectiveness of various disposal measures. The main reason is that: traffic control, signal control, information guidance and other rapid traffic disposal methods have their own characteristics and scope of application. Due to road traffic accidents Due to the sporadic nature of traffic accidents, it is impossible to determine the application area of ​​various rapid disposal measures based on the information of traffic accidents in time
