Traffic conflict intervention method, apparatus, and system of road plane intersection

Abstract

The invention, which relates to the technical field of road traffic management, particularly discloses a traffic conflict intervention method of a road plane intersection. The method comprises: acquiring information data, including the speed of a motor vehicle on a main road, a distance between the motor vehicle and the intersection on the main road, a left-turning vehicle at the intersection on the main road, and a moving target on a crosswalk at an intersection of a branch road and the main road, of an intersection traffic object; according to the data information of the traffic object, setting intervention parameters; determining whether a traffic conflict exits; and if so, determining a conflict intervention strategy for the traffic conflict according to the traffic object informationdata, the intervention parameters, and a preset traffic conflict risk level. In addition, the invention also provides a traffic conflict intervention apparatus and system of a road plane intersection.With the disclosed method, the intervention on the potential traffic conflict is realized effectively; and accidents are prevented.

Description

technical field [0001] The invention relates to the technical field of road traffic management, in particular to a road level intersection traffic conflict intervention method, a road intersection traffic conflict intervention device and a road intersection traffic conflict intervention system including the road intersection traffic conflict intervention device. Background technique [0002] According to research, there are a large number of low-grade roads or village roads that are not suitable for installing traffic lights in my country. Level intersections that connect to high-grade roads. This type of intersection usually lacks effective traffic control means, and traffic conflicts frequently occur, often becoming accident-prone points. In addition, there are often unreasonable design factors in low-grade roads or village roads, which further affect the safety and efficiency of such intersections. Therefore, for low-grade roads without traffic signal lights or village r...

Problems solved by technology

This type of intersection usually lacks effective traffic control means, and traffic conflicts frequently occur, often becoming accident-prone points

In addition, low-grade roads or village roads often have unreasonable design factors, which further affect the safety and efficiency of such intersections

Therefore, for low-grade roads without traffic signal lights or village roads connected to high-grade roads at level intersections, relying solely on traffic civilization awareness and conscious behavior of traffic participants is not enough to effectively solve the problem of traffic safety. Other intervention methods to solve the problems of frequent traffic conflicts at such intersections, difficulty in balancing traffic efficiency and safety, etc.

[0003] Although domestic intervention devices for intersection traffic have been developed, there are mainly the following problems or deficiencies: First, the intervention is only aimed at motor vehicles, and the comprehensive intervention effect is poor; second, static signs are usually used for warning reminders, which have poor flexibility and no obvious warning effect , can not play a good role in accident prevention; third, most of them are used in conjunction with traffic lights, and do not have the conditions for application at intersections without signal lights
