A visual guidance system for curved road sections of long bridges on expressways

Abstract

The invention relates to the technical field of road traffic ancillary facilities, in particular to a visual guidance system for curved sections of long and large bridges on expressways. The visual guidance system for the curved sections of long and large bridges on the expressways comprises curved section indication signs, linear guidance marks, yellow and black elevation marks, arrow marks, outline marks, cat eye track spikes, yellow concussion marks and double-white solid lines. The curved section indication signs are arranged at the positions, near the curved sections. The linear guidancemarks are arranged on bend guardrails on the outer side of the curved sections. The yellow and black elevation marks are arranged on the guardrails which are located on the two sides of the curved sections. The arrow marks are arranged on the road surface of the curved sections. The outline marks are arranged on the lower edges of the guardrails which are located on the two sides of the curved sections. The cat eye track spikes are arranged the side lines of the roads which are located on both sides of the curved sections. The yellow concussion marks are arranged on the outer sides of the sidelines of the roads which are located on both sides of the curved sections. The double-white solid lines are arranged on the middle lines of the roads of the curved sections.

Description

technical field [0001] The invention relates to the technical field of road traffic auxiliary facilities, in particular to a visual guidance system for curved road sections of long bridges on expressways. Background technique [0002] According to relevant statistics, in the past 10 years, the traffic accidents on curved road sections in my country accounted for about 10% of the total accidents, the fatal accidents on curved roads accounted for about 20% of all fatal accidents, and more than 70% of serious road accidents occurred in technical indicators.

Problems solved by technology

The curve is one of the main alignments of the highway. Due to the complex and changeable road conditions, it is easy to cause psychological stress and driving fatigue to the driver. Concrete guardrails are often used on the highway bridge curve section, and the visual guidance facilities are not perfect. Insufficient information is obtained, and the problem of driving fatigue due to the monotonous driving environment is also prominent, these are important factors leading to accidents

[0003] In the relevant specifications of the alignment, the requirements for the setting of sight-guiding facilities are not high. The setting of sight-guiding facilities on the highway bridge curve section is relatively simple, and the stimulation effect on drivers is poor; the scale of some facilities is small, and large vehicles The visual recognition effect is poor; when driving at night, due to the poor reflective effect of the facilities, the driver can obtain less information, and basically cannot play an inductive role
