Alamance County, N.C.


We had a large role in the modernization and expansion of the Burlington-Graham computerized traffic signal system which includes new controller and cabinet assemblies at approximately 203 signals. We performed traffic signal cabinet inventories, traffic signal designs and electrical programming details for 2070LX controllers using ASC/3 software at five intersections.

Additionally, our design department performed QA/QC reviews on utility make-ready plans, CCTV camera technical reports, construction plans and specifications to ensure that the correct materials and wiring per regulation were installed at all locations. We also conducted CCTV camera electrical service field investigations and utility coordination for all our sites. This project utilized our CEI, traffic, transportation design and ITS/signals departments.

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.
