Problems solved by technology

[0002] In the current road risk level prediction and early warning methods, there are deficiencies in the active risk prevention and control methods for traffic flow and individual vehicles. The monitoring equipment is installed on two-way two-way lanes. Collision traffic accidents will affect the passage of upstream vehicles and cause certain damage to the road. At this time, the upstream vehicles do not know that an accident has occurred at the downstream accident-prone point, and the upstream vehicles will drive normally according to the current speed limit of the road, but the existing active risk prevention and control methods do not control the vehicle speed of the upstream traffic flow. Control, causing a large number of upstream vehicles to flow into downstream accident points, resulting in traffic congestion at accident-prone points and reducing the efficiency of road transportation

Embodiment 1

[0030] The embodiment of the present invention provides an active prevention and control system for road operation risks that takes into account both traffic flow and individuals, including: a cloud processing center platform, a variable information board, and multiple traffic flow monitoring devices;

[0031] Each traffic flow monitoring device is set on the gantry on the side of the road, and each traffic flow monitoring device includes a traffic event detector, a network camera and a millimeter-wave radar; the network camera includes an edge computing unit; the traffic event detector is used to detect the road in real time When there is an abnormal traffic event on the Internet, the vehicle information of the abnormal traffic event is extracted and transmitted to the cloud processing center platform, where the vehicle information includes the model, color and license plate; the network camera is used to photograph the vehicle of each vehicle on the road Information, and tran...

Embodiment 2

[0040] The embodiment of the present invention provides a method for active prevention and control of road operation risks that takes into account both traffic flow and individuals, including the following steps:

[0041] Step 1: Determine the high accident frequency points according to the historical traffic data, and set up multiple traffic flow monitoring devices along the upstream of the high accident frequency points. Vehicle information, as well as the vehicle information and speed information of each vehicle on the corresponding sub-section; wherein, the vehicle information includes model, color and license plate;

[0042]Among them, historical traffic data includes accident types and accident rates; abnormal traffic events refer to: illegal parking, traffic jams, illegal retrograde, cross-line driving, slow driving or speeding;

[0043] Specifically, the specific determination process of the prevention and control strategy is: according to the traffic flow risk level a...

Abstract

The invention belongs to the technical field of traffic safety, and in particular relates to a system and method for active prevention and control of road operation risks that take into account both traffic flow and individuals. The system includes: a cloud processing center platform, a variable information board and a plurality of traffic flow monitoring devices; each traffic flow monitoring device is arranged on a gantry on the side of the road, and each traffic flow monitoring device includes a traffic event detector, IP camera and mmWave radar. Aiming at the problem of prevention and control of the safety level of the two-way two-lane highway, the present invention prevents and controls the operational risk of the road from the perspective of speed induction and information reminder. According to the traffic situation, determine the current road risk level, control the vehicle speed of the upstream traffic flow, avoid traffic congestion at accident-prone points caused by a large number of upstream vehicles, and effectively avoid the occurrence of traffic accidents.
