anchor Description
The Traffic Signal System Modernization (TSSM) program provides on-going, life-cycle replacement and maintenance of critical subsystems and equipment from the network communication paths throughout the County and is relayed to both Transportation Management Center (TMC) and traffic control equipment in the field. The life-cycle replacement plan ensures the transportation network system, communication network, and the hardware in the TMC (servers, workstations) remains up to date with industry and national standards and, new technologies employed by the Traffic Division.
anchorEstimated Schedule
Phase I - completed Phase IIA - completed Phase IIB - ongoing Life Cycle Upgrades - and beyond.
anchorCost Change
adjusted for inflation. Funding for and was added.
anchor Justification
The transportation systems remain highly reliable, but we must keep the system up to date through life cycle replacement. The technologies in the industry have advanced over the years which necessitates the modernization of equipment such as (aggregators, communication cables and modems, software, and servers) to interface with the current transportation control system. The life cycle replacement will provide stability and greater level flexibility to manage the transportation demands as well as take advantage of the newer technology that is being introduce to the industry.
