Method for setting vibration deceleration markings at long downhill sharp turn sections of mountain roads

Abstract

The invention discloses a method for setting vibration deceleration markings at long downhill sharp turn sections of mountain roads. According to the method, setting positions of vibration deceleration markings at serious traffic accident-prone sections and spacing distances between the vibration deceleration markings are determined on the basis of cognitive psychology and man-machine ergonomics principles, so as to scientifically and reasonably carry out deceleration control and prompt on the drivers before entering the uphill and downhill sharp turn sections of mountain roads. The invention provides a set of careful and effective setting method for setting vibration deceleration markings at long downhill sharp turn sections of mountain roads.

Description

technical field [0001] The invention belongs to the technical fields of traffic safety technology and traffic management, and relates to a method for setting vibration deceleration markings on long downhill and 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 account for a 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. Large longitudinal slopes often appear at the same time, and the road sight distance is poor, which greatly increases 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 major traffic accidents in my country in recent ...

AI Technical Summary

Problems solved by technology

However, the setting method of deceleration markings in practical applications is suitable for expressways, and the use effect is not good in mountainous downhill and sharp curves.

In the practice of traffic engineering, there is a lack of an effective method for setting vibration deceleration markings on long downhill and sharp bends of mountainous highways, and it cannot provide effective speed control for roads prone to major traffic accidents in mountainous areas.
