Traffic Control Network Upgrades to Ethernet/Copper with Actelis

WYDOT, the Wyoming Department of Transportation, is using Actelis Networks' Intelligent Transportation Systems (ITS) networking solution to revamp the state capital's transportation network, which serves nearly 60,000 Cheyenne residents. Actelis'ML690 aggregation switches, ML622 and ML680 EADs were deployed across the city's copper network to provide real-time troubleshooting and monitoring capabilities.


Specifically, WYDOT is using Actelis' ITS solution to backhaul data from wireless vehicle detection systems. Pucks located on the ground transmit vehicle presence data wirelessly back to a receiver and then this data is transported by Actelis' ITS solution back to the Traffic Operations Center (TOC), where it is used to synchronize traffic lights and ensure the smooth flow of traffic.


The existing copper network is used to communicate with any traffic controller, at any intersection, from any location. Previously, WYDOT had been using 1,200 baud modems, radio systems and multiple protocols. The new network used Actelis' high-speed, Ethernet-based ITS solution.


"We took a giant step forward with Actelis' ITS solution," said Jerry Downs, State Electrical Engineer for Operations at WYDOT. "The number one goal was the ability to easily communicate with all of our traffic controllers, which enables us to improve the efficiency of how we move and monitor traffic throughout the city... We looked at fiber as an alternative solution, but with the results we observed with Actelis, a fiber-optic network could not be justified. With Actelis' ITS solution, I am getting the speeds and reliability I need, so why would I want to spend that kind of money on fiber? It just didn't make sense." http://www.actelis.com http://www.dot.state.wy.us/wydot/
