Metretek to deploy M2M systems for traffic control
Metretek announced that two departments of transportation in the Southeastern U.S. would deploy its InvisiConnect machine-to-machine (M2M) system to remotely monitor and control traffic signal controllers. The departments were not identified. The plug-and-play, IP-based system—which replaces legacy wired and wireless technologies—will provide DOT mobile personnel with “untethered and secure access” to traffic signal equipment, Metretek said. The system provides connectivity via public digital cellular networks.
