A Line-of-Sight Induction System for Horizontal and Longitudinal Sections of Expressway Tunnels

Abstract

The invention relates to the technical field of traffic safety, in particular to a line-of-sight guidance system for a horizontal and vertical combined road section of an expressway tunnel, including a horizontal and vertical combined road section of an expressway tunnel composed of a straight road section and a curved slope road section, and the straight road section specifically refers to a road section located at a curved road. 200m in front of the slope, the line-of-sight guidance system for the combined horizontal and vertical sections of expressway tunnels includes Zorla’s illusion road markings and low-level high-frequency contour markers on the straight section, and the starting point and curved section of the straight section. Lane indicators at the starting point, arrow-shaped peephole road studs on curved slopes, asymmetric trapezoidal road markings on curved slopes, high-position and low-frequency belt lines on the outside of curves on straight roads and curved slopes, Middle-medium frequency belt line 1 on the outside of the curve on straight road sections and curved slope sections, low mid-high frequency contour marks on curved road sections, and medium-medium frequency belt line 2 on the inside of the curve on straight road sections and curved slope sections . It is beneficial to enable the driver to see the outline of the tunnel clearly, and visually perceive the curves and slopes.

Description

technical field [0001] The invention relates to the technical field of tunnel traffic safety, in particular to a line-of-sight guidance system for horizontal and vertical sections of expressway tunnels. Background technique [0002] For the combined horizontal and vertical road sections of expressway tunnels, the driver will complete the driving task of the curved slope section in a short time, and the driver's sight distance is poor on the curved slope section. There is a deviation in the judgment of the road, and the special road section with the combination of curves and slopes will cause the driver to have greater physical and psychological discomfort when driving on this road section. The driving task of the horizontal and vertical tunnel section is complex, which can easily cause changes in the driver's driving psychology. The speed and trajectory of the vehicle often fluctuate greatly. The ability is poor, accelerating when going uphill on the slope road section, and...

AI Technical Summary

Problems solved by technology

In terms of existing related technologies, mainly by enhancing the lighting brightness of the tunnel section, the driver can see that there is a horizontal and vertical combination section in front, resulting in high installation and operation costs, and it cannot effectively reflect the changes in the alignment of the tunnel section. In addition, it is difficult to apply to long-distance horizontal and vertical tunnel sections, so there is an urgent need for a safe, effective and economical line-of-sight guidance system for tunnel horizontal and vertical sections.
