Problems solved by technology

Severe weather may lead to poor road conditions such as low visibility, ice, water, snow, skidding, etc. on urban highway sections, which will lead to various hidden dangers of traffic accidents, and may even cause major traffic accidents
For example, in severe weather such as heavy fog, rain and snow, it is difficult to see the driving area ahead when the vehicle is driving, which makes the risk of traffic accidents higher

Embodiment 1

[0082] see figure 1 As shown, it is a schematic diagram of the overall networking architecture of an intelligent transportation system provided by the embodiment of the present application, including:

[0083] Road condition information collection module 11; roadside processing equipment 12; cloud server 13; traffic management platform 14; vehicle 15; user terminal 16; equipment conversion unit 17; traffic lights 18;

[0084] Wherein, the roadside processing device 12 includes a roadside communication unit and an edge computing unit;

[0085] The road condition information collection module 11 includes information collection equipment deployed at intersections and roadsides, such as cameras and laser radars; laser radars can collect the speed of each vehicle on the road, cameras can collect various image information or video information on the road, and laser radars can collect various image information or video information on the road. Both the camera and the camera can uplo...

Embodiment 2

[0097] The road condition notification method provided by the embodiment of the present application is applied to a road condition notification device, see figure 2 As shown, it is a schematic flow chart of a road condition notification method provided in the embodiment of the present application, including the following steps:

[0098] S201: Obtain road condition information of a target area.

[0099] S202: Determine vehicle information whose distance between the current driving position and the target area is within a preset distance range.

[0100] S203: Send the road condition information of the target area to the terminal matching the vehicle information.

[0101] Wherein, the target area may be various sections of the road, including an intersection, and a middle section of the road. Wherein, the road condition notification device may be a roadside processing device in the target area, wherein the roadside processing device includes a roadside communication unit and a...

specific Embodiment 1

[0104] The traffic notification device is the roadside processing device in the target area:

[0105]In a possible scenario, for example, in heavy fog, heavy rain, and heavy snow, the driver's sight distance is limited, and the traffic indication information at the intersection cannot be seen clearly, which may lead to traffic accidents. Safety risks increase, so the roadside processing device can acquire traffic instruction information in the target area when executing step S201.

[0106] In a possible implementation manner, when step S201 is implemented, the roadside processing device may communicate with the device conversion unit through the roadside communication unit to acquire traffic indication information in the target area, and the format of the acquired traffic indication information may be It cannot be directly transmitted to the vehicle-mounted terminal, so the format of the acquired traffic indication information can be converted into a format that can be transmi...

Abstract

The invention relates to the technical field of intelligent traffic, and particularly relates to a road condition notification method and device. The method comprises the steps of acquiring road condition information of a target area; determining the information of a vehicle of which the distance between a current travel position and the target area is within a preset distance range; and sending the road condition information of the target area to a terminal matched with the vehicle information. By using the abovementioned scheme, the road condition information of the road section can be quickly sensed, the vehicle can be informed of the road condition information in time, the occurrence probability of traffic accidents is reduced, and intelligent traffic is achieved.

Description

technical field [0001] The present application relates to the technical field of intelligent transportation, in particular to a road condition notification method and device. Background technique [0002] With the rapid development of road network construction, there are more and more traffic safety problems caused by bad weather. Severe weather may lead to poor road conditions such as low visibility, ice, water, snow, skidding, etc. on urban highway sections, which will lead to various hidden dangers of traffic accidents, and may even cause major traffic accidents. For example, in severe weather such as heavy fog, rain and snow, it is difficult to see the driving area ahead when the vehicle is driving, which makes the risk of traffic accidents higher. Contents of the invention [0003] In view of this, the embodiment of the present application provides a road condition notification method and device, which can quickly sense the road condition information of the road sect...
