Method and system for preventing tramcars from collision at intersection

Abstract

The invention relates to a method and system for preventing tramcars from collision at an intersection. The method includes performing video data acquisition and / or microwave data acquisition on the interested area of the intersection to obtain the vehicles and pedestrian information in the interested area; analyzing the vehicles and pedestrian information to obtain the analyzed result of potential pedestrians and vehicles and / or vehicle collision; providing the vehicle and pedestrian information to the drivers of the tramcars according to the analysis result, wherein the vehicles and / or pedestrians with the potential pedestrians and vehicles and / or vehicle collision is warned. The video detection and microwave detection are fused, the real-time monitoring analysis is carried out to the intersection for the tramcars to pass, the vehicles and the pedestrians in a certain range of the intersection are monitored, the quantity and position are detected, the information is sent to the tramcars, so that the tramcars can take timely collision prevention measures, and the travelling safety of the pedestrians and the vehicles can be guaranteed.

Description

technical field [0001] The invention relates to the field of vehicle-road coordination, in particular to a method and system for preventing collisions of trams at intersections. Background technique [0002] Vehicle-road coordination is one of the key technologies of intelligent transportation. It adopts advanced wireless communication and a new generation of Internet technology to realize real-time information interaction between vehicles and vehicles in an all-round way. Based on the collection and fusion of full-time and spatial dynamic traffic information, vehicle-road collaboration carries out vehicle collaborative active safety and road collaborative management, fully realizes the effective coordination of people, vehicles and roads, ensures traffic safety, and improves traffic efficiency, thereby forming a safe, efficient and environmentally friendly system. transportation system. [0003] Vehicle-road collaboration includes key technologies such as wireless communic...

Problems solved by technology

[0005] As a green transportation tool, trams bring convenience and environmental protection to people. At the same time, there are some safety hazards. Taking Jiangsu trams as an example, trams drive in the central green belt of the road and when they arrive at road intersections, they give The already complex road intersections have increased traffic hazards, and vehicle-vehicle conflicts and human-vehicle conflicts follow

[0006] Existing intersection surveillance is just ordinary video surveillance, which cannot be monitored automatically. It needs human help to monitor. There is no danger warning. It can only provide judgment basis after the accident. It can reduce the occurrence of traffic accidents and ensure the safety of pedestrians and vehicles. no strong guarantee

In particular, at the intersection where the tram passes, due to the complexity of the environment, it is also an accident-prone area, and the existing ordinary video surveillance cannot guarantee its traffic safety
