Les cerveaux sont grands ouverts, l'utilisation des LED dans l'industrie du transport n'est plus une idée rare. Les LED ont obtenu de très bons résultats en matière de détournement de trafic et d'avertissement, et elles ont une bonne réputation dans la surveillance des grands écrans. Maintenant, l'affichage à led montre une nouvelle utilisation dans l'industrie du transport : l'affichage à led de trottoir.
Affichage LED trottoir
The led sidewalk display in Piccadilly Circus, London, England is 22m long and is made of waterproof led display. When pedestrians want to cross the road, stand in a specific circle on the side of the road, the circle will change from red to green, and the middle of the road The zebra crossing shown on the LED display will appear, and drivers driving on the road will also see the LED dynamics for the first time, and will stop and wait for pedestrians to pass by. In this way, it can avoid the occurrence of other things.

This intelligent LED display screen can also monitor and detect road conditions in real time. When a pedestrian is about to cross the road, the sidewalk can interact with the pedestrian, automatically plan the pedestrian's route, and remind fellow vehicles to pay attention to the pedestrian. At the same time, the display screen can also adjust the width of the led humanity crossing display screen according to the number of pedestrians to increase the speed of pedestrians.

In addition to Piccadilly Circus, other places have gradually changed in this regard. The Solar Innovator team composed of students from Beijing University of Aeronautics and Astronautics and Beijing Jiaotong University, Sun Xiaokang, Zhang Yizhou, Yang Yifeng and Liu Enyou, used to compete in the 2015 Maker Marathon. Proposed "Solar Intelligent Pedestrian Traffic System". Similar to the smart sidewalk mentioned above, they envisaged laying their own solar powered LED display lights on the sidewalk. When pedestrians pass the sidewalk, the smart system can monitor the road conditions and pedestrian dynamics through the camera. If a vehicle is approaching the sidewalk quickly, whether it is a green or red light, the color of the indicator light will change on the sidewalk to remind pedestrians to pay attention to potential hazards.

The intelligent system monitors the number of pedestrians through cameras mounted on traffic lights. If there are more pedestrians, it will automatically adjust the signal time to give people more time to pass, otherwise it will reduce the passing time. When pedestrians have passed, the traffic lights will change more quickly.

Although the sidewalk LED display can remind the driver, it is not better than the pedestrian looking up and observing the road conditions by himself. They would rather wait five minutes than fight for a second. Safety is more important than anything else.
