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...

Examples

Embodiment

[0032] Example: see Figure 1 to Figure 13 , a method for safely passing pedestrian crossings at night is that at least one end of the pedestrian crossing is provided with a light projection device 1, which can emit more than one layer of horizontal azimuth fan-shaped projection laser 101 and project it above the pedestrian crossing, the horizontal azimuth fan-shaped projection laser When a pedestrian encounters an obstacle, it is projected to form a linear laser. When a pedestrian passes through the crosswalk, the laser is projected on the person to form a luminous warning sign line 100 surrounding the human body. Stereoscopic imaging luminous warning signs such as Figure 8 As shown, pedestrians always wear the luminous warning sign in the process of crossing the pedestrian crossing. The dynamic luminous warning sign can play the role of attracting the attention of vehicle drivers and slowing down to avoid it earlier, and pedestrians can cross the sidewalk more safely.
