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 reasons for rollovers and crashes are that the speed of turning and the angle of turning are unreasonable. These road sections lack effective deceleration Reminder signs and linear guidance

Embodiment Construction

[0048] The present invention will be further described below in conjunction with embodiment and accompanying drawing.

[0049] Based on the principles of cognitive psychology and ergonomics, the present invention determines the comprehensive setting method of traffic signs on the continuous sharp curve section of the mountainous road, so as to scientifically and reasonably give the driver deceleration prompts and warnings before entering the road section prone to serious and extraordinarily serious traffic accidents on the mountainous road. Linear induction, specifically as figure 1 As shown, a detailed description can refer to the Summary of the Invention.

[0050] The "Technical Guidelines for the Implementation of Highway Safety Guarantee Projects" stipulates that the standard for a single sharp curve section in mountainous areas is that the design speed is less than 60km / h, the average radius is less than 120m, and the parking sight distance is less than the parking sight di...

Abstract

The invention discloses a comprehensive arranging method for traffic signs in continuous sharp turn sections of mountain highways. The comprehensive arranging method is characterized in that on the basis of cognitive psychology and man-machine ergonomics principles, warning signs, speed limiting signs and linear inducing signs are determined at the road sections where serious major traffic accidents easily occur, so as to further scientifically and reasonably perform deceleration prompt and induction indication before a driver drives into the continuous sharp turn sections of a mountain. The comprehensive arranging method is a careful and effective arranging method for the comprehensive arranging of the traffic signs at the continuous sharp turn sections of the mountain highways.

Description

technical field [0001] The invention belongs to the technical fields of traffic safety technology and traffic management, and relates to a method for comprehensively setting traffic signs on continuous sharp curve sections of mountainous highways. 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 occupy 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, and small curve radius. Many road sections often have continuous curves. Appears, the road line of sight is poor, greatly increased 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 proportion of serious and extraordinarily serious traffic accidents in my c...
