Uncovering the Mysteries of the New Direction of Smart Cities
The new LED lighting traffic system embedded in the road has been put into trial in London. It can detect pedestrians and other vehicles, and replace street lights and pipeline signs in real time according to road conditions to alert the driver of possible danger. Especially when pedestrians or bicycles appear in the blind area of the driver’s eyes, the road will display a red light warning.
The new LED-embedded road was jointly developed by Umbrellium in the United Kingdom and Direct Line, an automotive insurance company. In addition to the embedded LED road surface, the system also includes a high-definition camera for capturing pedestrian and vehicle information and assisting the system in real-time feedback.
Zebra crossing and road safety have always been an important and complex part of the public transport system. However, from the beginning of the zebra crossing design in the 1940s to the highly developed traffic, the way people cross the road has not changed much. The increase in traffic accidents has made the perfect zebra crossing and pedestrian traffic system a necessary consideration for smart city design in the future.
LED street light turns into charging station and provides Wi-Fi service
Street lights are another application of LEDs in smart city traffic systems. According to Philips’ survey data, there are more than 300 million street lights worldwide, of which less than 10% use LED bulbs, of which less than 1% can centrally control switches and monitor street lights.
In the smart city of the future, LED street lamps will become the mainstream not only because they are more energy-efficient, but also LED street lamp poles will become multifunctional street lamps. U.S. Tower and Philips Lighting jointly developed a smart streetlight that not only provides energy-efficient LED lighting, but also provides wireless network coverage facilities for telecommunications companies. It also incorporates features of urban landscape and landscape lighting.
In San Diego, intelligent street lights with sensing capabilities will increase from more than 40 pilots to 3,600. The detection range will reach 160 square miles, which is equivalent to half of the entire city. The street lamp is designed by GE and cooperates with Intel, AT&T, ShotSpotter and other manufacturers to provide more applications, including monitoring air pollution, surrounding traffic conditions and parking information, and tracking gun sound sources in the gunshots. .
In the United Kingdom, the government worked with OVO, a clean energy company, and Ubitricity, a German technology company, to retrofit a small number of street lights to provide electric vehicle charging services. In response to the United Kingdom’s ban on the sale of petrol and diesel vehicles in 2040, the government has fully implemented the EV and clean energy policies.
In China, with the development of NB-IoT, smart streetlights are also accelerating. Intelligent control of future urban lighting will also become mainstream. Huawei, Shanghai Sansi and other vendors all provide intelligent street light solutions such as sensors, security monitoring, information release, network, billing, and emergency calls.
