Texas DOT uses hardened Ethernet switches and wireless for traffic control

Attention: open in a new window.

To monitor and manage traffic flow, and to view accidents for better emergency response, TxDOT wanted to send video back to the Ft Worth Traffic Control Centre (TCC) from 150 of the busiest intersections in the city. When there was a problem at one of the intersections off of a Ft Worth exit ramp, traffic tended to back up onto the main highway and slow traffic along an extended section of the highway.

TxDOT chose GarrettCom’s hardened P62 switches to provide Ethernet connectivity, 100Mb bandwidth, and reliable operation in extreme temperature weather environments. The P62 Switches were designed for outdoor deployment, and feature a unique thermal technique (patent pending) using the case as a heat sink in order to get the heat out of the electronics. The resulting lowered temperature electronics increases reliability.
