Three-dimensional rhythm type information visual environment designing method for extra-large highway bridge

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 super-large highway bridges, in particular to a design method for a three-dimensional rhythmic information visual environment of super-large highway bridges. Background technique [0002] Superhighway bridges are the main control nodes of expressways: their driving speed is generally 80-120KM / H. Compared with ordinary roads, the consequences of bridge traffic accidents are often more serious, and usually lead to secondary traffic accidents, and cause long-term traffic jams. Domestic investigations and research on bridge traffic accidents found that due to excessive speed of the driver The types of accidents such as rear-end collisions and collisions with safety barriers caused by the failure to take measures such as braking in time are very prominent in bridge traffic accidents, accounting for 37.77% and 30.4% of the total number of traffic accidents respectively. Look, there are the mos...

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
