Problems solved by technology

However, at present, when vehicles are driving on the road, it is difficult to know in time which areas that are about to pass through have abnormal traffic events, and they will still be integrated into the areas where abnormal traffic events occur, thereby aggravating traffic congestion.

Embodiment 1

[0088] See figure 1 As shown, a schematic diagram of the overall networking architecture of an intelligent transportation system provided by an embodiment of this application includes:

[0089] Information acquisition module 11; roadside communication unit 12; edge computing unit 13; cloud computing server 14; traffic management platform 15; vehicle 16; user terminal 17; equipment conversion unit 18; traffic signal lamp 19;

[0090] The information acquisition module 11 includes cameras and lidars deployed at intersections and intermediate sections; lidars and cameras can collect road condition information at road intersections or intermediate sections, and upload it to the cloud computing server 14 and / or through the roadside communication unit 12 The edge computing unit 13 analyzes the road conditions by the cloud computing server 14 and / or the edge computing unit 13;

[0091] The roadside communication unit 12 is used to receive the road condition information collected by the info...

Embodiment 2

[0102] See figure 2 As shown, a schematic flow chart of a method for notifying a traffic incident provided by an embodiment of this application includes the following steps:

[0103] S201: Collect road condition information of the target area.

[0104] Among them, the target area can be an intersection of a road or an intermediate section of the road. The road condition information includes at least one of the following information: surveillance images and / or surveillance videos of the target area, the driving speed of each vehicle in the target area, and text information used to describe the road condition information of the target area.

[0105] Exemplarily, the surveillance image and / or surveillance video of the target area may be surveillance images and / or surveillance videos acquired by cameras installed in the target area, and may also be driving images acquired by on-board camera equipment installed in each vehicle in the target area And / or video, it may also be an image and...

specific Embodiment 1

[0111] It is understandable that under normal circumstances, each vehicle will drive straight along each vehicle lane, change lanes, turn left and right, U-turn, etc., but in the event of a more serious traffic accident, such as a collision between multiple vehicles, or a certain vehicle When the car is out of control, the trajectory of these vehicles will be different from other normal vehicles, and the body will rotate, such as being in the middle of the road, or the speed of the car will be out of control.

[0112] When the road condition information includes the surveillance image and / or surveillance video of the target area, the embodiment of the present application uses the following steps to detect whether an abnormal traffic incident occurs in the target area according to the road condition information:

[0113] At every set time period, extract the driving trajectory of each vehicle in the target area during the set time period based on multiple monitoring images and / or mul...

Abstract

The application relates to the technical field of intelligent transportation, in particular to a traffic event notification method and device. The method comprises the steps: collecting road conditioninformation of a target region; and according to the collected road condition information of the target area, detecting whether an abnormal traffic event occurs in the target area; if so, determiningidentification information of a vehicle associated with a current driving path and a target area, and notifying a terminal matching the identification information of the abnormal traffic event occurring in the target area. According to the scheme, the traffic abnormal condition of the road section can be quickly sensed, the abnormal condition of the road section can be timely notified to vehiclesabout to drive into the road section, the traffic jam is prevented, and intelligent traffic is realized.

Description

Technical field [0001] This application relates to the field of intelligent transportation technology, and in particular to a method and device for notifying traffic incidents. Background technique [0002] With the complexity of the urban traffic road network and the increase in the number of cars, traffic congestion has become more serious. When some abnormal conditions occur during the driving of the vehicle, such as a traffic accident in a certain section of the road, traffic jams are prone to occur. However, at present, it is difficult to know in a timely manner which areas where abnormal traffic incidents have occurred when vehicles are driving on the road, and they will still be integrated into the areas where abnormal traffic incidents have occurred, thereby increasing traffic congestion. Summary of the invention [0003] In view of this, the embodiments of the present application provide a traffic incident notification method and device, which can quickly sense abnormal ...
