Method for safely passing through crosswalk at night

Abstract

The invention discloses a method for safely passing through a crosswalk at night. At least one end of the crosswalk is provided with a light projection device which is capable of emitting lasers comprising more than one layer and horizontally projecting in the shape of a fan. When a pedestrian passes through the crosswalk, the lasers are projected onto the body of the pedestrian to form luminous warning sign lines which surround the human body. The multi-layer horizontal luminous warning sign lines are longitudinally arranged along the height of the pedestrian and further form a three-dimensional imaging luminous warning sign. The pedestrian is always accompanied by the luminous warning sign during the process of passing through the crosswalk. The dynamic luminous warning sign can more effectively attract the attention of drivers of vehicles to reduce the speed and to give way to the pedestrian in advance, so that the pedestrian can more safely pass through the crosswalk. The method for safely passing through the crosswalk at night provides pedestrians with safe passage at night by mounting the light projection devices on two sides of the crosswalk and is applicable to urban roads,town road intersections and road sections where relatively more pedestrians cross the road. The method has advantages of safety, reliability and reasonable design.

Description

[0001] This application is a divisional application of an invention patent application with the application date of 2015-03-20, the application number of 201510124342.9, and the title of "Safe pedestrian crossing at night and light projection device". technical field [0002] The invention discloses a method for safely passing a pedestrian crossing at night, which belongs to the technical field of safe passage on sidewalks in urban streets according to the International Patent Classification Table (IPC), and in particular relates to safety scheme measures for pedestrian crossings at night. Background technique [0003] 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 ...

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
