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

A speed limit sign and road section technology, which is applied in the field of traffic safety technology and traffic management, can solve the visual interference of cart drivers without considering the mountainous terrain, the speed of entering corners is fast, and there is no distinction between small cars and large cars. Speed ​​and other issues, to reduce the risk of overturning and crashing, high accuracy, and improve traffic safety.

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.

Embodiment Construction

[0033] The present invention will be further described below in conjunction with embodiment and accompanying drawing.

[0034] Based on the principles of cognitive psychology and ergonomics, the present invention determines the continuous setting method of speed limit signs for different vehicle types on road sections prone to accidents in mountainous areas, so as to scientifically and rationally guide drivers before entering road sections prone to serious accidents in mountainous areas. Deceleration control and prompts, such as figure 1 As shown, a detailed description can refer to the Summary of the Invention.

[0035] By collecting the basic data of a highway accident-prone road section, the mileage stake number of the starting point of the mountainous road accident-prone road section is K10+200, and the sharp curve radius of the road section is 100 meters, and the lateral slope of the road surface is 7%. Before entering the accident-prone road section, use the traffic spe...

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...
