GREENVILLE TRAFFIC SIGNAL SYSTEM UPGRADE

Greenville, N.C.

PROJECT DESCRIPTION

As the city grew and their signal system reached over ten years of age, the City of Greenville sought out consultants to expand and rehabilitate their systems. Our ITS/Traffic Engineering department is part of the team doing the design of the expansion and rehabilitation. The project consists of 155 signalized intersections, 24 CCTV cameras and 58 miles of fiber optic cable.

Our team will be designing the entire Ethernet-based, single mode fiber optic communications system, CCTV camera system and 14 traffic signal plans. The new cameras installed at the intersections will combine the collection of movement data (like turning movements or car counting) with traffic surveillance, allowing the City to gather more streamlined data.

We also developed emergency vehicle preemption wiring details for the City’s new GPS-based preemption system. This system allows emergency vehicles to pass through intersections more safely by communicating their GPS location to the traffic signals.
