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 present invention provides a method and device for processing road congestion information. In the present invention, after the first roadside unit receives the second roadside congestion information obtained from the second vehicle by the second roadside unit through the V2X technology, it can pass the V2X technology, sending the second road congestion information to the first set of vehicles connected to itself. Since the second roadside unit and the first roadside unit are arranged at successive intersections, and the transmission speed of V2X technology is relatively fast, the first vehicle can change lanes in time when it knows that the nearest intersection ahead is congested. , to avoid driving into congested intersections. Compared with the prior art, the driver of the vehicle can only understand the road congestion state of the specified number of kilometers ahead. In most cases, when the driver travels to the road of the specified number of kilometers ahead, the road In the case that the congestion state of the traffic has changed, the real-time performance is high.

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...
