Traffic landscape design method for urban cross-river bridges based on multi-frequency color information

Abstract

The invention relates to an urban river-crossing bridge traffic landscape design method based on multi-frequency color information. Yellow and black or blue and white lamp pole facade marking lines are arranged on the lower edges of two sides of lamp poles, at the interval of 25 m to 35 m, of a bridge; transverse visual illusion marking lines are arranged at the positions, corresponding to the yellow and black or blue and white lamp pole facade marking lines, of the road surface; road surface protruding road marks are arranged at the interval of 12.5 m to 17.5 m, and therefore the space intermediate frequency visual information flow is jointly formed. Yellow and black or blue and white road side facade marking lines are arranged on the lower edge and the top of curb stone at intervals of 1.5 m to 3 m, and therefore the space high frequency visual information flow is formed; a set of road surface transverse white folding lines is arranged every four lamp poles in the advancing direction, and yellow or blue bridge handrails are arranged on the road side, so that the space low-frequency visual information flow is formed. The multi-frequency color information flow can effectively improve the speed perception, the distance perception and the visual sensitivity under high and low illuminance of a driver in the vehicle driving process, and unification of urban river-crossing bridge traffic landscape coordination and vehicle driving safety is achieved.

Description

technical field [0001] The invention relates to the technical field of urban bridge traffic design, in particular to a traffic landscape design method for urban cross-river bridges that improves the driver's vehicle speed control and vehicle distance maintenance capabilities, thereby realizing the unification of urban cross-river bridge landscape coordination and bridge traffic safety benefits. Background technique [0002] It is common for vehicles to overspeed on bridges across rivers in cities, and accidents of rear-end collisions and collisions with safety guardrails occur frequently. Urban river-crossing bridges are generally relatively long, ranging from hundreds of meters to several thousand meters. The traffic safety facilities and landscape on the bridge are generally insufficient, the environment is monotonous, and there are few reference objects; drivers lack a sense of direction and speed, resulting in widespread speeding. Vehicles are driving on bridges with hi...

Problems solved by technology

[0007] The technical problem to be solved by the present invention is to overcome the monotonous traffic landscape setting of the existing urban cross-river bridges, few types of landscapes, low density, and constant colors, and it is difficult to ensure the driver's accurate cognition of the traffic environment under various illumination conditions. , to provide a traffic landscape design method for urban cross-river bridges based on multi-frequency color information, which helps drivers maintain a clear driving state and improves the driver's cognitive ability under different illumination conditions
