Description

Road speed limit tablet

Technical Field

The utility model belongs to the technical field of traffic safety, a road speed limit tablet is related to.

Background

At present, the speed-limiting signs of domestic roads are all fixed speed-limiting signs arranged according to the road grades, and traffic managers set the traffic-limiting speed of the road sections according to the construction materials, the gradient, the turning angle and the like of the roads. When the weather and the driving road condition change and the road traffic speed needs to be changed, the road administration department and the traffic police department generally place temporary speed limit signs at the entrance of the expressway or in front of the section where the abnormal condition occurs for prompting. However, when the vehicle is already running on the expressway or is about to enter an abnormal section, the travel limit speed of the current section cannot be known. The current solution is for the road administration to manually place temporary speed limit signs in response to emergency situations. The scheme not only consumes a great deal of manpower and time, but also has no timeliness, and the information lag is likely to increase the incidence rate of the interlinked traffic accidents. The speed limit prompted by the road administration department is based on data detected by a monitoring instrument arranged at a fixed place, a detection point cannot represent the condition of the whole road section, and the road administration department cannot accurately monitor the speed limit in real time when the weather change or the driving road condition change occurs on a local road section. Therefore, road vehicle drivers cannot intuitively feel the magnitude of environmental change when the road safety level is reduced due to a plurality of factors such as rain, snow, fog and the like, and in addition, when abnormal conditions such as traffic jam, traffic accidents and the like occur on the front road, the speed-limiting warning function of the existing fixed speed-limiting sign is immediately disabled, and the drivers continue to drive by feel, so that the continuous traffic accidents are caused. In the annual expressway traffic accidents, the traffic accidents caused by the fact that measures cannot be taken timely due to weather changes and emergency situations of the front road section account for a large proportion.
