The Exult team led a collaborative effort to enhance the redundancy and reliability of the City of Charlotte’s traffic signal system and information technology network.

The project consisted of three primary aspects:

1. Planning, design, coordination, integration and construction administration for a new back-up datacenter for the signal system and information technology network.
2. Planning, design, coordination, integration and construction administration for revitalization of the current primary data center, including replacement of the end-of-life core switch, removal of all serial technologies, and re-cabling for efficient future maintenance.
3. Design and construction administration of phased fiber optic splicing to enable each networked endpoint (traffic signals, cameras, City buildings, etc.) to communicate with both a primary and back-up data center via eight (8) redundant path rings around the City.

The team implemented a phasing plan for the cutover that would minimize downtime for each of the City’s traffic signals. With a redundant network in place, the team worked closely with City I&T on data center, network hardware and server upgrades at the existing Traffic Management Center. Exult Engineering worked closely with City ITS staff, I&T staff, a fiber optic splicing contractor, and a data center contractor to successfully complete these tasks. The project has resulted in enhanced resiliency and redundancy for the entire signal system and City IT network.
