Cliff-near low-grade road curve slope section grading linear induction system

Abstract

The invention relates to the technical field of traffic safety of cliff roads, in particular to a graded linear guidance system for a cliff-near low-grade road curve slope section, which divides the cliff low-grade road curve slope section into an observation section, an approaching section and a curve section, and performs graded linear guidance according to the sections. Ground guiding marks are arranged on the ground. A low-flashing-frequency contour structure is arranged on the observation section, a middle-flashing-frequency contour structure is arranged on the close section, a high-flashing-frequency contour structure and an annular reflective structure are arranged on the curve section, and triangular prism gantries are arranged at the starting position of the observation section, the junction of the observation section and the close section and the junction of the close section and the curve section. And vertical surface marks are arranged on all the protective piers. By the adoption of the structural arrangement, early warning and dynamic early warning are conducted on a driver through low-position induction of the road surface, middle-position induction of the road side and high-position induction of the space above the road surface, so that the safety of the cliff-near slope road section is guaranteed, and the driving safety in the daytime and at night is improved.

Description

technical field [0001] The invention relates to the technical field of traffic safety on cliff-facing roads, in particular to a graded linear guidance system for curved sections of cliff-facing low-grade roads. Background technique [0002] With the strengthening of our country's infrastructure, more attention has been paid to the development of transportation in remote areas, so there are more and more roads in various terrains, most of which are cliff roads. [0003] The curved and slope section of the cliff-facing road is an accident-prone area, and the cause of the accident is analyzed. It is found that due to the remote location of the cliff-facing road, the lighting conditions are often poor, and it is usually two-way and two-lane. Due to poor lighting conditions, when the vehicle drives to the cliff-side section, the driver is often vague about the road boundary. At the same time, due to the influence of the curved section, it is easy to make a wrong judgment. At thi...

Problems solved by technology

Due to poor lighting conditions, when the vehicle drives to the cliff-side section, the driver is often vague about the road boundary. At the same time, due to the influence of the curved section, it is easy to make a wrong judgment. At this time, the vehicle is likely to rush out of the road or into the opposite lane.

[0004]The layout of traffic safety facilities on the cliff-side section is not perfect
