A sight-guiding system for low-level lighting on super-large bridges on urban expressways in foggy areas

Abstract

The invention relates to the technical field of traffic safety facilities, in particular to a low-level lighting sight guidance system for super-large bridges on urban expressways in foggy areas, including high-frequency low-level lighting guidance information, medium-frequency high-level guidance information, low-frequency high-level guidance information, and high-frequency low-level lighting guidance information. Including raised road signs set on the road surface, combination system of curb façade markings set on both sides of the road and low-level guardrail lights, and fixed-slope guardrails set on the middle zone of the road. Lane sideline signs on both sides, low-frequency high-level induction information include portal structures set above the road. The present invention improves the driver's sense of speed, sense of direction and sense of distance on the super-large bridge section of the city in the foggy area through a series of combined design of lighting with different dimensions and frequencies and sight-guiding facilities, thereby improving the driver's ability to keep the lane and follow the car. Distance maintaining ability and speed perception ability.

Description

technical field [0001] The invention relates to the technical field of urban traffic safety facilities, in particular to a low-level illumination line-of-sight induction system for extra-large bridges on urban expressways in foggy areas. Background technique [0002] On the one hand, due to the particularity of the location, the hazards of traffic accidents on bridges are much higher than those on other road sections, posing a higher degree of threat to traffic safety. On the other hand, the driver’s driving environment on super-large bridges is more monotonous, and his speed control ability, lane keeping ability and direction perception ability are all weakened, which puts forward higher requirements for the design of lighting sight guidance facilities on super-large bridge sections. For cities in foggy areas, the visibility of traffic safety facilities will be greatly reduced in dense fog, the driver's sense of direction, speed and position will drop sharply, and the risk ...

[0002] On the one hand, due to the particularity of the location, the hazards of traffic accidents on bridges are much higher than those on other road sections, posing a higher degree of threat to traffic safety

On the other hand, the driver’s driving environment on super-large bridges is more monotonous, and his speed control ability, lane keeping ability and direction perception ability are all weakened, which puts forward higher requirements for the design of lighting sight guidance facilities on super-large bridge sections. Requirements, for cities in foggy areas, the visibility of traffic safety facilities is greatly reduced in dense fog, the driver's sense of direction, speed and position are sharply reduced, and the risk of driving is rapidly increasing, especially in dense fog at night. , the degree of ambiguity of the driving environment is further improved, and the danger of the driver in the process of driving is becoming more and more intense. Driving needs to ensure traffic safety on large bridge sections
