Wireless Interconnect - Gwinnett County

One signal, Gwinnett County Department of Transportation

Columbia Engineering conducted a study to justify a traffic signal for a county park, checked traffic signal warrants, and designed the signal and extensive new sidewalk coverage to bring the project full-circle. The signal is at a T-intersection and is supported by a single, twin-arm steel pole. The controller is connected to GCDOT’s traffic signal system through a cellular modem.
