Comprehensive arranging method for traffic signs in continuous sharp turn sections of mountain highways

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...

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 signs

[0004] At present, the setting methods of deceleration, warning signs and linear guidance signs in practical applications are suitable for expressways, and the use effect is not good in continuous sharp curves in mountainous areas; The speed limit reminder and linear induction effect of continuous curves are not obvious
