Technical Field

The invention relates to the technical field of traffic facilities, in particular to a pedestrian crossing safety facility.

Background

At present, with the rapid development of city construction in China, the management of urban roads and crosswalk intersections becomes one of the important tasks of traffic management. The existing pedestrian crossing is arranged independently on a plane, only a single pedestrian crossing zebra crossing and a traffic indicator light are adopted for management, and people needing to pass through the pedestrian crossing are prompted to pass according to the change of road management.

In the prior art, a chinese patent with publication number CN207065425U discloses a safe crosswalk facility, aiming at providing a crosswalk facility which is provided with an illumination system to enhance the brightness of crosswalk at night and reduce traffic accidents on crosswalk at night. The street lamp comprises a zebra crossing arranged on a pedestrian crossing, wherein two ends of the zebra crossing are respectively provided with a supporting rod, and an illuminating system for night illumination is arranged between the two supporting rods; the illumination setting includes the steel support between two bracing pieces, evenly is equipped with a plurality of LED lamps on the steel support and is used for the solar cell panel for the power supply of LED lamp. Through set up lighting system above the pedestrian crossing make the pedestrian pass through the pedestrian crossing night, safer, reduce the emergence of traffic accident. In addition, the solar cell panel supplies power to the LED lamp, and the touch delay switch is used for controlling the LED lamp, so that the solar cell panel is more energy-saving and environment-friendly. And the whole structure is stable, convenient and practical.

The above prior art solutions have the following drawbacks: although the illumination system can enhance the brightness on the pedestrian crossing at night, the occurrence of traffic accidents on the pedestrian crossing at night is reduced; however, when some drivers who are out of duty meet traffic lights on pedestrian crossings, the drivers often get a rush to the lights or even run the red lights in order to finish passing in a short time. At this time, if a pedestrian passes through the pedestrian crossing, traffic accidents are easily caused, and the safety of the pedestrian is difficult to guarantee.

Disclosure of Invention

Aiming at the defects in the prior art, the invention aims to provide a pedestrian crossing safety facility which has the effect of improving the safety of pedestrians passing through a pedestrian crossing.

The technical purpose of the invention is realized by the following technical scheme:
