Embodiment Construction

[0012] The present invention proposes a method for identification and early warning of highway road traffic safety black spots, the method is composed of a black spot identification module and a traffic safety early warning module, such as figure 1 , where the black spot identification module is mainly to use the historical data of expressway traffic accidents to analyze the influencing factors and sensitivities of traffic accidents on expressway sections, and to judge the traffic safety factors of expressway sections under different roads, traffic and environments , to determine the black-spot sections of expressways under different roads, traffic, and environments. The traffic safety early warning module is mainly based on the traffic flow running state of the expressway, combined with the road conditions and traffic environment, and according to the driver behavior characteristics and vehicle performance characteristics in the expressway traffic flow, the expressway managers...

Abstract

The invention belongs to the technical field of road traffic safety, and particularly relates to a highway road traffic safety dark-spot road recognition and early-warning method. The highway road traffic safety dark-spot road recognition and early-warning method is realized based on the historical data of highway traffic accidents. The method analyzes the influence factors and the sensitivity of traffic accidents on the road section of a highway, and judges the traffic safety factor of the road section of the highway in different road, traffic and environment conditions. Meanwhile, based on the method, the dynamic early-warning for the operation safety of the highway traffic flow is realized in combination with the behavior characteristics of drivers on the highway, the performance characteristics of vehicles on the highway, the road condition and the traffic environment. Therefore, the operation safety of the highway traffic is improved, and the accident rate of the highway traffic is reduced.

Description

technical field [0001] The invention belongs to the technical field of road traffic safety, and in particular relates to a method for identifying and early warning black spot sections of expressway road traffic safety. Background technique [0002] With the continuous increase of expressway mileage and the continuous improvement of expressway network in our country, expressway plays an increasingly important role in traffic travel, logistics transportation, and promotion of social and economic development. At the same time, due to the characteristics of large traffic, fast speed, complex vehicle composition, and imperfect road infrastructure, highway traffic accidents are common. Traffic accidents on expressways have brought huge economic losses to the country, and also caused permanent physical and property trauma to both parties involved in the accident. Although the expressway management, operation and other departments have adopted many effective countermeasures and met...
