We are providing detailed plans, specifications, and estimates for the rehabilitation and expansion of Greenville, North Carolina’s computerized traffic signal system. The system will consist of up to 150 intersections and 27 exclusive and 67 shared closed-circuit television (CCTV) cameras, utilizing a new redundant circuit Ethernet communications system composed of 58 miles of single-mode fiber optic communications cable and one wireless link. This project will include new 2070 controllers and associated cabinets, installation of new traffic control center and signal shop equipment, emergency vehicle preemption, and GRIDSMART® video detection systems that automate turning movement counts at 71 intersections. It will also include two connected vehicle (CV) pilot corridors consisting of 30 signalized intersections. This CV pilot deployment will use a hybrid approach by installing both DSRC and cellular technologies at each intersection.
