A Smart Life

摘要

As night falls on Xiongan New Area, about 100 km southwest of Beijing in Hebei Province, something unique happens: Streetlights come on and automatically adjust their brightness according to the number of pedestrians and vehicles around them. Passersby sit casually on the benches beside the streetlights, where they can charge their phones on the poles' outlets and access a free Wi-Fi network. The streetlights are also equipped with multifunction cameras, enabling them to automatically collect and transmit traffic information.
