Safe pedestrian crossing method at night and light projection device

Abstract

The invention discloses a pedestrian crosswalk safe passage method at night and light projection equipment. At least one end of the pedestrian crosswalk is provided with a light projection device. The device can emit more than one layer of fan-shaped laser beams projected in the horizontal direction. When pedestrians pass through the pedestrian crosswalk, The laser is projected on the human body to form a luminous warning sign line surrounding the human body. The multi-layer horizontal luminous warning sign line extends longitudinally along the height of the person to form a three-dimensional imaging luminous warning sign. Pedestrians always wear this warning sign when crossing the crosswalk. Luminous warning sign, the dynamic luminous warning sign can play the role of attracting the attention of vehicle drivers and slowing down and avoiding in advance, and pedestrians can cross the sidewalk more safely. The invention provides pedestrians with safe passage at night by installing light projection devices on both sides of the pedestrian crossing, and is applicable to urban roads or urban road intersections and road sections where pedestrians cross the road relatively concentrated, and has the advantages of safety, reliability, and reasonable design.

Description

technical field [0001] The invention discloses a method for safely passing a pedestrian crossing at night and a light projection device, which belongs to the technical field of safe passage on sidewalks in urban streets according to the International Patent Classification (IPC), and in particular relates to safety schemes and measures for passing the sidewalk at night. Background technique [0002] According to urban road traffic regulations, pedestrian crossing facilities such as pedestrian crossings, pedestrian overpasses or pedestrian crossing underpasses should be set up at road intersections and sections where pedestrians cross the road. The method marked stipulates the walking range of pedestrians crossing the lane. At night or when the weather is bad and the sky is dark, pedestrians cross the crosswalk without attracting the attention of passing vehicles, resulting in traffic accidents. At night or in a dark environment, the light is poor, and when encountering speed...

AI Technical Summary

Problems solved by technology

At night or in a dark environment, the light is poor, and when encountering speeding vehicles, pedestrians crossing the sidewalk or zebra crossing will become especially dangerous, and there will be great safety hazards
