Multi-source-information-fusion-based marked line paving method for especially large highway bridge

Abstract

The invention discloses a multi-source-information-fusion-based marked line paving method for an especially large highway bridge. The method comprises the following steps: arranging a visual illusion marked line with an optical flow rate of 6-12HZ on a rail; alternately arranging red distance confirming lines and yellow distance confirming lines on a side wall; arranging a white broken line distance confirming marked line on the bridge floor; transversely arranging a vibrating and reducing marked line on the bridge floor above a pier; vertically arranging a road-side vibrating belt on the bridge and close to the rail; and coating the surfaces of the red distance confirming lines, the yellow distance confirming lines, the white broken line distance confirming marked line, the vibrating and reducing marked line and the road-side vibrating belt with a retro-reflecting material. The marked line provided by the invention has the effects of controlling vehicle speed and keeping distance and further has a certain anti-corrosion function for the bridge.

Description

technical field [0001] The invention belongs to the technical field of traffic safety facilities, and in particular relates to a marking laying method for extra-large highway bridges based on multi-source information fusion. Background technique [0002] Extra-large highway bridges refer to bridges with a total span length of more than 1000m and a single span span of more than 150m, which are mainly channels for crossing water or valleys. Existing super-large highway bridges have the following defects: first, the monotonous landscape easily induces speeding behavior and driving fatigue; second, when crossing waters or valleys, it is easy to form low-visibility environments such as fog and steam, causing drivers to fail to maintain a safe distance between vehicles and not to follow the rules. The third is that large crosswinds are likely to cause the risk of vehicle deviation, and the lack of anti-collision facilities (adding traffic safety auxiliary facilities on extra-large...

Problems solved by technology

Existing extra-large highway bridges have the following defects: first, the monotonous landscape can easily induce speeding behavior and driving fatigue; The third is that large crosswinds are likely to cause the risk of vehicle deviation, and the lack of anti-collision facilities (adding traffic safety auxiliary facilities on extra-large highway bridges will easily increase the load of the bridge itself, and generally use as little as possible) may easily lead to deviation The vehicle collided with the bridge guardrail and caused a serious traffic accident
