Method and system for visual speed control on continuous downhill section of highway

Abstract

The invention discloses a continuous highway downslope section vision speed control method and system. The method comprises the following steps that firstly, a continuous downslope warning sign is arranged on the edge of a road at a continuous highway downslope section and at a first section in front of a grade change point in the downslope direction, and concrete isolation piles are arranged every a first preset distance to form a space high-frequency information stream; secondly, raised pavement marks are arranged every a second preset distance at the first section in front of the grade change point in the downslope direction and the second section behind the grade change point to form a space low-frequency information stream; thirdly, a plurality of visual illusion marking lines are laid at the sections from the grade change point in the upslope direction; and a plurality of visual illusion marking lines are laid at equal intervals within the preset range from the grade change point in the downslope direction. According to the continuous highway downslope section vision speed control method and system, the gradient illusion of the continuous highway downslope section of a driver can be avoided, the control over the vehicle speed of the downslope section is facilitated, and traffic safety is improved.

Description

technical field [0001] The present invention relates to highway traffic safety design, in particular to a design of traffic safety facilities for continuous downhill section of highway based on driving behavior and retroreflection, so as to improve the driver's speed perception and distance perception, and improve the driver's vision of the continuous downhill section. Illusion helps to achieve driving safety and comfort on the continuous downhill section of the highway. Background technique [0002] Traffic accidents frequently occur on highway sections, especially the downhill section of the highway is a highway accident-prone section. Due to the influence of terrain and project cost, in the linear design of the longitudinal section of the mountainous road, the local road section has to adopt the form of continuous downhill, such as figure 1 As shown, a continuous downhill section is formed. In 2004, deployed by the State Council, in order to reduce and prevent traffic a...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is: to overcome the imperfect traffic safety facilities of the continuous downhill section of the existing highway, the environmental characteristics of low illumination, and the serious slope illusion that is easy to occur - the technical problem of mistakenly identifying the continuous downhill section as the uphill section, Provide a visual speed control method for continuous downhill sections of highway based on driving behavior, improve the driver's visual illusion for continuous downhill sections, and help to achieve driving safety and comfort for continuous downhill sections of highways
