Description

TECHNICAL FIELD

[0001] The present application relates to a control method and device of a light-emitting zebra crossing and a computer storage medium, in particular to an adaptive light control method, device and computer storage medium of a light-emitting zebra crossing. BACKGROUND

[0002] The function of a zebra crossing is to guide pedestrians to cross the road safely. The traditional zebra crossing is printed on the road with white paint, providing a passage for pedestrians and traffic prompting. However, with the increase in the number of vehicles, the increase in vehicle speed and the upgrading of traffic environment complexity, the traditional zebra crossing sometimes cannot effectively prompt the vehicle drivers due to the influence of environmental conditions, and the effect of protecting pedestrians and improving traffic conditions is poor.

[0003] Some new light-emitting zebra crossings are also disclosed in the prior art. For example, a road surface prompting unit and an intelligent zebra crossing are disclosed in Chinese Patent No. 201811564006.6, which can display different color patterns according to the color of the traffic signal light to improve the visual prompting effect. A city intersection intelligent traffic control method and system are disclosed in Chinese Patent No. 202210163814.1, which controls the light-emitting zebra crossing mainly by switching control according to the state of the pedestrian signal light. The above-mentioned prior art does not consider the influence of environmental conditions on the prompting effect of the light-emitting zebra crossing, and the control form is relatively single, so the protective effect of the light-emitting zebra crossing on pedestrians cannot be fully exerted. SUMMARY

[0004] In view of the defects of the above-mentioned prior art, the present application provides an adaptive light control method for a light-emitting zebra crossing, which solves the problem of weakening of the warning effect of the zebra crossing caused by changes in environmental conditions and improves the safety protection effect of the zebra crossing on pedestrians.

The traffic congestion state is divided into two cases of congestion and non-congestion, and this condition can be obtained by using a visual sensor.

[0037] According to the environment information, one of the multiple working state modes of the light-emitting zebra crossing is selected to work;

[0038] Among them, the working state mode includes:

[0039] Mode one, off mode, corresponding to the environment information of one of the day and sunny, the day and cloudy, and non-dim and non-congestion;

[0040] Mode two, orange light maximum brightness fog lamp working mode, corresponding to the environment information of one of the day and haze, the day and rain, snow and fog, the night and haze, the night and rain, snow and fog, and the deep night;
