Problems solved by technology

[0004] However, most of the existing real-time traffic accident prediction models can only predict the probability of traffic accidents, and cannot predict the current severity level of traffic accidents, and cannot give the current probability of traffic accidents of each severity level

Embodiment

[0106] The traffic flow and traffic accident data of the I-880 road in California, U.S. in 2008 are used to test the detection accuracy of the present invention for traffic accidents of different severity levels. According to the steps 10) to 30) of the present invention, the accident data of property damage accident PDO, minor personal injury accident BC, serious injury or death accident KA and non-accident data of the road section are collected. The established traffic data samples include 532 PDO samples of property damage accidents only, 203 BC samples of minor personal injury accidents, 59 KA samples of serious injury or death accidents, and 7940 non-accident samples (that is, when there is no traffic accident, the use of traffic flow The detection equipment collects the traffic flow parameters of the road section to form a non-accident sample).

[0107] Utilize above-mentioned traffic flow data sample, according to step 50) of the present invention, obtain the traffic fl...

Abstract

The invention discloses a vehicle regulating and controlling method of lowering a probability of traffic accidents of different severity. The method includes the steps: (10) obtaining traffic information of an accident road section; (20) collecting traffic data of the accident road section before accidents happen; (30) collecting the traffic data of the accident road section in a normal state; (40) setting up a traffic flow data sample; (50) setting up a probability function of the traffic accidents of three stages after standardization; (60) measuring and calculating the probability of occurrence of the traffic accidents of the different severity; (70) measuring and calculating a probability threshold value of the traffic accidents of the different severity; (80) detecting the probability of the traffic accidents of the different severity of the road section in real time, and regulating and controlling vehicles; and (90) repeating the step (80), carrying out detection on the probability of the traffic accidents on the road section in following set time T, and regulating and controlling the vehicles until the detection is finished. The vehicle regulating and controlling method detects the probability of the traffic accidents of the different severity in real time, regulates and controls the vehicles, and improves driving safety.

Description

technical field [0001] The invention belongs to the technical field of express road intelligent transportation, and in particular relates to a vehicle control method for reducing the probability of traffic accidents with different severity levels. Background technique [0002] According to the degree of casualties in traffic accidents, traffic accidents can be divided into different grades. The lightest accident level is only property damage (no casualties) accident, and the heaviest accident level is fatal accident. Traffic accidents of different severity have different impacts on economic loss and road traffic. Traffic accidents with higher severity levels not only cause huge social and economic losses, but also have a serious impact on the operating efficiency of expressways and urban expressways. Therefore, how to prevent traffic accidents with higher severity levels, such as serious injuries or fatal accidents, has important practical value and economic significance. ...
