Embodiment Construction

[0071] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0072] The embodiment of the present invention provides a method for processing road congestion information, which is applied to the first roadside unit, the first roadside unit is set at the first intersection, and the roadside unit (RSU) is fixed at a special position along the road A physical device, similar to a mobile base station, that needs to communicate not only with the on-board unit, but also with other roadside units.

[0073] refer to figure 1 , ...

Abstract

The invention provides a method and device for processing road congestion information. In the invention, after a first road side unit receives a second road congestion message obtained by a second road side unit from a second vehicle through the V2X technology, the second road congestion information can be transmitted to a first vehicle set connected with the first road side unit through the V2X technology. Because the second road side unit and the first road side unit are sequentially disposed at a continuous road intersection and the transmission speed of the V2X technology is higher, the first vehicle can timely change the lane when determining that the last road intersection of the front is in a congestion state, so as to avoid the congested road intersection. Compared with a method inthat prior art that enables a vehicle driver to just obtain the congestion state of a road within a specified number of kilometers in the front in the prior art but cannot determine that the road congestion state has changed in most conditions when the driver drives the vehicle to the road within the specified number of kilometers in the front, the method is higher in real-time performances.

Description

technical field [0001] The invention relates to the field of intelligent transportation, more specifically, to a method and device for processing road congestion information. Background technique [0002] Due to sudden traffic accidents or traffic peaks on the road, there will be more vehicles queuing up on the road, and the vehicles behind will drive to the congested area, which will aggravate the road congestion. Therefore, a method for avoiding traffic jams is proposed in the prior art. First, it is judged whether the road is congested, and the congested state is sent to the roadside variable release board, so that the vehicles behind can know the congested state of the road ahead in time, and timely Change lanes to avoid traffic jams. Wherein, the road congestion state is divided into two states: no road congestion and road congestion. [0003] Among them, the roadside variable release boards are arranged on one side of the road in sequence along the road. Since a road...
