Traffic engineers in New York City will soon be able to reboot malfunctioning stoplights without leaving their desks, thanks to a new IoT project. The city’s Department of Transportation is working with Transition Networks to deploy Power-over-Ethernet (PoE+) switches at 10,000 traffic intersections.
PoE systems pass electric power and data on single cable to various devices, including wireless access points, IP cameras, and VoIP phones. The Managed Hardened Gigabit PoE+ Switch from Transition is designed for outdoor environments and can supply up to 30 watts per port on all eight ports simultaneously.
The switches power cameras and sensors at intersections. The cameras track traffic and pedestrian flows while the sensors count cars and support the city’s Connected Vehicle project. The data is transmitted to the city’s traffic monitoring center.
