Method for continuously arranging vehicle type-divided speed limitation boards on accident-prone sections of mountain highway

Abstract

The invention discloses a method for continuously arranging vehicle type-divided speed limitation boards on accident-prone sections of a mountain highway. The positions of the vehicle type-divided speed limitation boards on the major traffic accident-prone sections of a mountain region and the continuous arranging method are determined on the basis of principles of cognitive psychology and man-machine ergonomics, and then decelerating prompting and warning are scientifically and reasonably given to a driver before the driver enters the accident-prone sections of the mountain region. A detailed and effective arranging method is provided for continuous arrangement of the vehicle type-divided speed limitation boards on the accident-prone sections of the mountain highway.

Description

technical field [0001] The invention belongs to the field of traffic safety technology and traffic management technology. Based on the principles of cognitive psychology and ergonomics, the driver's driving behavior is deeply analyzed to obtain a continuous speed limit plate for different types of road accident-prone road sections in mountainous areas. Setting method. Background technique [0002] my country is a mountainous country, and the mountainous area accounts for more than 70% of the country's land area. Mountainous roads account for a relatively large proportion of my country's road network, and most of these mountainous roads are low-grade roads, surrounded by mountains and rivers, with winding roads, many continuous curves, small curve radii, and poor road sight distance, which greatly improves The probability of road traffic accidents and the casualty rate. According to the statistics of my country's annual report on road traffic accidents, a considerable propor...

Problems solved by technology

[0003] Statistics show that rollovers and crashes are the main forms of major accidents that occur on these road sections, and the main reason for rollovers and crashes is that the turning speed is too fast, and these road sections lack effective speed limit warning signs

At present, on these accident-prone road sections in mountainous areas, the speed limit signs do not distinguish between vehicle types, without considering the visual interference of large vehicle drivers due to the complexity of mountainous terrain, and without distinguishing the driving behavior characteristics of small vehicles and large vehicles. In practical application, the existing speed limiting devices on mountainous roads are not effective.
