A Design Method of Stereo Rhythmic Information Visual Environment for Extra-Large Highway Bridges

Abstract

The invention relates to the technical field of safety design of extra-large highway bridges, and particularly discloses a three-dimensional rhythm type information visual environment designing method for an extra-large highway bridge. A roadside multi-beat information flow, a planar multi-beat information flow and a multicolor information flow are involved, wherein the roadside multi-beat information flow is formed by wave crest height changes of roadside rhythm type information on bridge guardrails; the planar multi-beat information flow is formed by planar rhythm type information marks, road surface note marks and transverse speed prompting marks of a road surface; the multicolor information flow is formed by combining the bridge guardrails and the rhythm type information in different colors in a designing unit and combining different designing units in different colors. The characteristics of undiversified visual environment of a poor information shooting road section and reference deficiency are improved, hypnotic effects of a road are alleviated, the speed judgment accuracy of a driver is improved, the response time of the driver is shortened, and the driving safety and comfort of the driver are improved.

Description

Technical field [0001] The invention relates to the technical field of safety design of extra-large highway bridges, in particular to a method for designing an extra-large highway bridge's three-dimensional rhythmic information visual environment. Background technique [0002] As the main control node of the expressway, the super highway bridge: its driving speed is generally 80~120KM / H. Compared with ordinary roads, the consequences of bridge traffic accidents are more serious. They usually lead to the occurrence of second traffic accidents and cause long-term traffic jams. The domestic investigation and research on bridge traffic accidents found that the driver’s speed was too high. The type of accidents caused by rear-end collisions and collisions with safety guardrails caused by failure to take measures such as brakes in time is very prominent in bridge traffic accidents, accounting for 37.77% and 30.4% of the total number of traffic accidents. At the same time, the time peri...

Problems solved by technology

[0006] In view of the above problems, the present invention provides a method for designing a three-dimensional rhythmic information visual environment for super-large highway bridges. By improving the characteristics of single visual environment and lack of reference in low-information intake sections, the "hypnotic" effect of the highway can be alleviated and the driver's speed can be improved. Judgment accuracy, reduce driver reaction time, improve driver driving safety and comfort
