Embodiment 1

[0038] see figure 1 , figure 1 It is a schematic flowchart of a tunnel traffic event detection method disclosed in the embodiment of the present application. Such as figure 1 As shown, the first aspect of the present application provides a tunnel traffic incident detection method, the method comprising:

[0039] S1, the vehicle in the tunnel detects the occurrence of a traffic incident through the equipped vehicle end;

[0040] S2. The receiving end outside the tunnel receives the traffic event information reported by the vehicle end of several vehicles in the tunnel;

[0041] S3. The receiving end determines whether a traffic event occurs in the tunnel based on the plurality of traffic event information and the corresponding vehicle types.

[0042] With the development of automobile technology, more and more vehicles are equipped with various detection devices, such as radars, cameras, etc. Using these intelligent devices supplemented by intelligent recognition algorithms...

Embodiment 2

[0062] see figure 2 , figure 2 It is a structural schematic diagram of a tunnel traffic incident detection system disclosed in the embodiment of the present application. like figure 2 As shown, the second aspect of the present application provides a tunnel traffic incident detection system, which corresponds to the method described in Embodiment 1;

[0063] The system includes a vehicle end and a receiving end;

[0064] The vehicle terminal is equipped on the vehicle to detect the occurrence of traffic incidents in the tunnel;

[0065] The receiving end is set outside the tunnel, and is used to receive the traffic event information reported by the vehicle end of several vehicles in the tunnel, and, based on the several traffic event information and their corresponding vehicle types, determine whether a traffic event occurs in the tunnel .

Embodiment 3

[0067] see image 3 , image 3 It is a schematic structural diagram of an electronic device disclosed in the embodiment of this application. like image 3 As shown, the third aspect of the present application provides an electronic device, the electronic device is set at the receiving end, and the device includes:

[0068] a memory storing executable program code;

[0069] a processor coupled to the memory;

[0070] The processor invokes the executable program code stored in the memory, and performs the following method steps:

[0071] receiving traffic event information reported by the vehicle end of a plurality of vehicles in the tunnel; and judging whether a traffic event occurs in the tunnel based on the plurality of traffic event information and their corresponding vehicle types.

Abstract

The invention provides a tunnel traffic event detection method. The method comprises the steps that S1, vehicles in a tunnel detect the occurrence of a traffic event through vehicle ends installed on the vehicles; S2, a receiving end outside the tunnel receives traffic event information reported by the vehicle ends of the plurality of vehicles in the tunnel; and S3, the receiving end judges whether a traffic event occurs in the tunnel based on the traffic event information and the respective corresponding vehicle types. According to the scheme of the invention, the problem of low reliability of detecting whether a traffic event occurs in a tunnel or not is effectively solved.

Description

technical field [0001] The present application relates to the field of intelligent transportation, in particular, to a method and system for detecting tunnel traffic incidents. Background technique [0002] Tunnels are an important part of the highway traffic system. In order to enable road managers or road network vehicles to keep abreast of the traffic conditions in the tunnels, it is very necessary to improve road network management capabilities and smooth conditions. At the same time, with the development of vehicle intelligence, more and more vehicles have the ability of traffic detection and transmission. For example, vehicles equipped with traffic incident detection devices can conduct on-site detection of traffic incidents in the surrounding area, or the vehicle members can Manually input traffic incident occurrence information, and then send it to the receiving device outside the tunnel through the Internet of Vehicles. However, since the field of vision in the tun...
