ITS Master Plan Cost Projections Cost data was analyzed to create cost projections for the implementation plan. Cost data was collected from TxDOT Low Bid data and vendor quotes. This section provides an overview of the cost data used for the major implementation plan components. The cost data is used for planning-level purposes only, and actual costs may vary. Cost projections completed for this study also incorporated a 15% contingency and engineering costs, which were assumed to be 10%. Recurring maintenance costs for cellular modems and ATMS were also included for appropriate years.
ITS Communication Infrastructure The communication infrastructure considered for this project was cellular modems. Table 5 details the cost data of cellular modems used in this study. A hardened ethernet switch is required for each modem. At the network level, a Layer 3 ethernet switch and network firewall are required.
