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.
