Mist zone city fast road super large bridge low-position lighting sight line induction system

Abstract

The invention relates to the technical field of traffic safety facilities, in particular to a mist zone city fast road super large bridge low-position lighting sight line induction system. High-frequency low-position lighting induction information, medium-frequency high-position induction information and low-frequency high-position induction information are included. The high-frequency low-position lighting induction information comprises convex road signs arranged on the road surface, curb vertical face signs and low-position fence lamp combined systems arranged on the two sides of the road and a fixed slope type fence arranged on the road halved zone. The medium-frequency high-position induction information comprises lane side boundary indication boards symmetrically arranged on the twosides of the road. The low-frequency high-position induction information comprises a door frame type structure arranged above the road. According to the mist zone city fast road super large bridge low-position lighting sight line induction system, through combined design of a series of lighting and sight line induction facilities different in dimensionality and frequency, the speed sense, the direction sense and the distance sense of drivers in the mist zone city super large bridge road section are improved, and accordingly the lane keeping capability, the vehicle following distance keeping capability and the speed sensing capability of the drivers are improved.

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
