Road condition information providing method based on intelligent traffic system and intelligent traffic system

Abstract

The embodiment of the invention provides a road condition information providing method based on an intelligent traffic system and the intelligent traffic system, and the method comprises the steps that an intelligent traffic road side unit generates local road condition information according to collected real-time road data, and transmits the local road condition information to a mobile edge computing platform; the mobile edge computing platform generates global road condition information according to the local road condition information sent by the intelligent traffic road side unit; and the mobile edge computing platform selects target road condition information from the global road condition information and sends the target road condition information to the vehicle through the mobile communication public network. Therefore, the vehicle can receive the target road condition information generated by the intelligent traffic system through the mobile communication public network under the condition that the vehicle is not provided with the vehicle-mounted unit. Meanwhile, the target road condition information is generated based on the global road condition information, so that the road condition information is richer than the local road condition information, the overall condition of the current road can be known more comprehensively, and the real-time performance is better.

Description

technical field [0001] The invention relates to the technical field of transportation, in particular to a method for providing road condition information based on an intelligent transportation system and an intelligent transportation system. Background technique [0002] In the prior art, when a vehicle is driving on the road, it is usually possible to know the real-time road conditions of the road through the vehicle navigation system and the mobile APP navigation system or the LTE-V2X (Long Term Evolution-Vehicle to Everything) Internet of Vehicles, for example, whether the road is Congestion, whether there are traffic accidents on the road, etc. [0003] However, the road conditions obtained through the navigation system are usually updated less frequently and rely more on the driving status transmitted by vehicles with positioning functions, so the road conditions in the navigation system may be different from the actual road conditions, and real-time road condition info...

Problems solved by technology

[0003] However, the road conditions obtained through the navigation system are usually updated less frequently and rely more on the driving status transmitted by vehicles with positioning functions, so the road conditions in the navigation system may be different from the actual road conditions, and real-time road condition information cannot be provided; At the same time, due to the positioning accuracy, it is impossible to prompt the real-time information of the lane-level accurate road

Obtaining road conditions through the V2X Internet of Vehicles usually requires the installation of an On-Board Unit (OBU) corresponding to the Internet of Vehicles in the vehicle, so that the road conditions can be obtained and transmitted through the Internet of Vehicles, which limits the transmission range of road condition information.
