A traffic controller is able to utilize input statistics and information from sensors and other devices to provide data about the number of vehicles and pedestrians waiting at a traffic intersection. An industrial Ethernet switch can expand the number of connection points for all Ethernet-based field equipment. Beyond standard connections,industrial Power over Ethernet (PoE) switches can provide power to cameras, wireless access points and other devices. The traffic controller can then use data to make adjustments by lengthening green lights or skipping turn signal phases when no vehicle is present in order to alleviate traffic.

All information needs to be brought back to a Traffic Management Center (TMC) for more management and control capabilities.Managed Ethernet switches with fiber-optic connections in each field traffic cabinet provide long-distance communication at high speeds and infrastructure redundancy to ensure data arrives at the TMC. As our transportation system further evolves into an intelligent transportation system, the need for higher speed communication and network redundancy is critical in maintaining a fast and reliable network.
