Traffic signal system device based on switching display of monochromatic white graphs without color blindness obstacles

Abstract

At present, traffic signals of all countries in the world are red, yellow, green and the like, and stop, switching preparation, passing and vehicle driving states are displayed by the aid of changes of icons and device appearances. Certain recent data shows that congenital achromatopsia and hypochromatopsia people account for about 6-8% of population, about 0.098 billion people in China and about0.4 billion people internationally are affected by congenital achromatopsia and hypochromatopsia, the people cannot reliably and correctly recognize traffic signals and vehicle driving state signals when passing through a traffic intersection, and therefore inevitable traffic potential safety hazards exist. Meanwhile, due to the fact that certain people with color weakness or color blindness obtain a driving license by memorizing pseudoisochromatic plates and finding other people to take an exam, traffic potential safety hazards are raised during driving of the kind of people. Therefore, a traffic signal device based on red, yellow and green and graph conversion is abandoned, and a traffic signal system device based on switching display of monochromatic white graphs without color blindnessobstacles is adopted and is used for traffic signal management and control and automobile driving state display, so that the problems can be solved fundamentally.

Description

technical field [0001] The invention relates to the technical field of road traffic signal devices. Background technique [0002] Road traffic control uses red, yellow, and green as the basic traffic signal device to control the traffic behavior of vehicles, pedestrians, and traffic at public road intersections, effectively solving the chaos, congestion, and traffic caused by disorderly passage. Traffic accidents and other issues, since December 10, 1868, the first rotatable gas-type red and green traffic lights appeared in Britain in history, and in 1912, American Lester White (Lester Wire) invented accordingly In 1920, William Potts, an American, improved the traffic lights into three lights on all sides. The red light means stop, the yellow light means ready to switch, and the green light means In Quebec, Canada, the red light was changed from a circle to a square, the yellow light was changed to a diamond, and the green light was a slightly smaller circle. It took about...

Problems solved by technology

[0004] The technical problem to be solved: the present invention abandons the current various road traffic signal devices and vehicles based on red, yellow and green color conversion, supplemented by graphics, text and device shape changes to show passing, ready to switch, and stop passing The signal device of the driving state adopts a traffic signal system device that can switch and display monochromatic white graphics without color blindness barriers, so as to avoid hundreds of millions of people with congenital color blindness and color weakness who cannot be reliably and correctly identified when passing through public road traffic intersections , red, yellow, and green signals, resulting in inevitable traffic safety hazards; at the same time, it solves the problem that color-weak and color-blind people cannot obtain driver's licenses, and lose the legitimate rights and interests of driving that the world should have
