Successfully managing Cranberry Township traffic using real-time traffic technologies
The Township is able to monitor and optimize traffic flow through key intersections from the new Traffic Operations Center. Video cameras will enable personnel to immediately spot incidents, track traffic developments in real time, and retime signals. The video equipment is used to manage traffic and not to enforce traffic regulations. Video is not recorded. The system is expected to accommodate the anticipated growth in traffic over the next 15 years.

Planning keeps pace with community growth
Getting to, through, and around Cranberry easily has been a key priority for the Township since the 1980s when its rapid growth as a population and commerce center began in earnest.
In the 60s, there was a single ‘blinker’ at Rt. 19 and Mars Rd. By the mid-90s, the Township boasted a fiber optic, closed loop system and 15 signals.
Today, the Centracs central-based control system features full-motion video cameras currently installed at fifteen key intersections. Through partnerships and agreements with neighboring Adams and Marshall Townships, Cranberry operates 48 signals and currently 27 are interconnected for traffic flow and efficiency.
TOC state-of-the-art equipment includes controllers, cabinets, back-up generators, decorative poles, ADA accessible pedestrian walkways and activation buttons.
Of special note, all traffic signal lamps in Cranberry use LEDs in place of traditional tungsten bulbs in every signal face. Also, EVP, (Emergency Vehicle Pre-emption) is a sound-based system that listens for emergency sirens and assigns priority to those vehicles.
