Self-adaptive induction system for road tunnel entrance area of curved slope section

Abstract

The invention relates to a slope road section highway tunnel entrance area self-adaptive induction system which comprises a roadside facility combination arranged in a highway tunnel entrance area, an induction coil arranged in an external area of a tunnel entrance and a retroreflection guide mark arranged on the side wall of an internal area of the tunnel entrance. The roadside facility combination comprises brightness gradual change energy storage self-luminous spherical protruding road signs and energy storage self-luminous induction columns, the brightness gradual change energy storage self-luminous spherical protruding road signs and the energy storage self-luminous induction columns are arranged on the road surfaces on the two sides of the road tunnel entrance area, brightness gradual change orange light-emitting balls are arranged on the energy storage self-luminous induction columns, and longitudinal flexible connecting rods are arranged between the energy storage self-luminous induction columns at intervals. The surface of the longitudinal flexible connecting rod is obliquely provided with a double-face staggered oblique induction sign, and the roadside facility combination controls the luminance through linkage of an induction coil. According to the invention, the purposes of guiding at a distance and not dazzling at a near position can be achieved, the night driving safety of a driver is improved, the size of a facility located at the rear side is increased, and the perception ability of the driver to a curve is improved.

Description

technical field [0001] The invention relates to a self-adaptive guidance system for a tunnel entrance area, in particular to an adaptive guidance system for a road tunnel entrance area in a curved road section. Background technique [0002] During the daytime, the visual environment inside and outside the entrance area of ​​the highway tunnel changes abruptly, and the transition is severe, which easily produces a black hole effect, making it difficult for the driver to distinguish the area of ​​the tunnel entrance area when the driving distance and viewing area are continuously shrinking when driving towards the tunnel entrance. Traffic and environmental conditions are unfavorable for drivers to make safe driving judgments and decisions, which in turn leads to frequent traffic accidents in the tunnel entrance area. On this basis, when the entrance area of ​​the highway tunnel is located on a curved road section, the driver still needs to deal with the dual changes of the slo...

Problems solved by technology

But at the same time, it also has shortcomings, that is, the self-illuminating facilities emit light around the light source, and the light intensity is consistent in all azimuth angles. When the driver is approaching the luminous facility, its brightness is constantly increasing, which is likely to produce a "dazzling" effect or a dazzling effect on the driver, affecting the comfort of the human eye, and leading to safety hazards
