Embodiment

[0045] The performance of the present invention in the detection of lateral impact traffic accidents is tested by utilizing the real traffic data of the road section where side impact accidents often occur on the I-880 road in California, USA. The traffic data collected by traffic flow detection equipment includes the average value of upstream traffic flow x 1 , the average speed of the downstream vehicle x 2 , the average value of the absolute value of occupancy difference between upstream adjacent lanes x 3 and the absolute value x of the speed difference between the upstream and downstream vehicles 4 .

[0046] According to step 10 and step 20) of the present invention, 157 traffic data samples of the accident group and 628 traffic data samples of the normal group were collected, totaling 785 samples.

[0047]The data samples are randomly divided into training samples and testing samples according to the ratio of 4:1. Among them, the training samples include 126 acciden...

Abstract

The invention discloses a vehicle regulating and controlling method of lowering a probability of lateral impact traffic accidents. The method includes the following steps: (10) obtaining accident group traffic data of an accident road section; (20) obtaining normal group traffic data of the accident road section; (30) setting up a traffic flow data total sample; (40) confirming a probability function of the lateral impact traffic accidents; (50) confirming the probability function of the lateral impact traffic accidents after standardization; (60) detecting the probability of the lateral impact traffic accidents on the road section in real time, and regulating and controlling vehicles; and (70) repeating the step (60), and carrying out detection on the probability of the lateral impact traffic accidents on the road section of next set time until the detection is finished. The vehicle regulating and controlling method obtains the real-time traffic data by utilizing traffic flow detecting equipment, detects the probability of the lateral impact traffic accidents on a fast road in real time, regulates and controls the vehicles, and reduces traffic accidents.

Description

technical field [0001] The invention relates to expressway intelligent traffic technology and side impact accident prevention technology, in particular to a vehicle control method for reducing the probability of side impact traffic accidents. Background technique [0002] With the continuous deepening of urbanization and motorization, since the mid-1980s, my country's transportation industry has developed rapidly, and expressways have gradually entered a period of rapid development. However, due to the rapid increase of the number of motor vehicles and improper management methods, the situation of highway traffic safety is becoming more and more severe. From 2007 to 2009, a total of 33,058 traffic accidents occurred on my country's expressways, and 18,130 people died. The death rate per 100 kilometers was 5.6 times that of other grades of highways, and direct property losses accounted for 37.6% of the total number of road traffic accidents in the country. At present, in ter...
