LED embedded in the road, avatar dynamic zebra crossing
A new type of LED light traffic system embedded in the road has been put into trial in London. It can detect pedestrians and other vehicles, and change the road lighting and pipeline number in real time according to the road conditions to remind the driver of possible dangers. In particular, when a pedestrian or bicycle appears in the driver's blind spot, the road will display a red light warning.
This new type of pavement with embedded LED lights was developed by the British company Umbrellium and the auto insurer Direct Line. In addition to the embedded LED pavement, the system also includes an HD camera that captures pedestrian and vehicle information and assists the system in making real-time feedback.
Zebra crossings and road safety have always been an important and complex part of the mass transit system, but from the embryonic form of zebra crossing design in the 1940s to the highly developed traffic today, the way people cross the road has not changed much. The increase of traffic accidents makes the perfect zebra crossing and pedestrian transportation system a necessary consideration for the design of smart cities in the future.
LED street lights turn into charging stations and Wi-Fi services are also available. Street lights are another application of LEDs in smart city transportation systems. According to Philips' survey data, more than 300 million street lamps worldwide use less than 10% of LED bulbs, and less than 1% of them can centrally control switches and monitor street lights. In the smart city of the future, LED street lights will not only become mainstream because of more energy-saving and more efficient, LED street light poles will also be transformed into a multi-purpose. American Tower and Philips Lighting have jointly developed a smart street light that not only provides energy-efficient LED lighting, but also provides a wireless network coverage facility for telecom operators, while also integrating into the urban landscape to take advantage of landscape lighting. In San Diego, USA, smart street lights with sensing capabilities will increase from more than 40 pilots to 3,600, with a detection range of 160 square miles, equivalent to half of the city. This streetlight is designed by GE's Current and works with other vendors such as Intel, AT&T, and ShotSpotter to provide more applications, including monitoring air pollution, surrounding traffic conditions and parking information, and tracking the source of the gunshots in the event of a shooting. . In the UK, the government has partnered with clean energy manufacturer OVO and German technology company Ubitricity to retrofit a small number of street lights to provide charging services for electric vehicles. In response to the UK's 2040 ban on the sale of gasoline and diesel vehicles, the policy of electric vehicles and clean energy was fully implemented. In China, with the development of NB-IoT, smart street lights have also accelerated. Intelligent control of urban lighting in the future will also become mainstream. Huawei, Shanghai Sansi and other manufacturers provide smart street lighting solutions, integrating sensors, security monitoring, information distribution, network, charging, emergency calls and other functions.
