TMC Overview

The Advanced Transportation Management System (ATMS) is composed of multiple integrated subsystems controlled and monitored from the Transportation Management Center (TMC). The ATMS is based on an open architecture that uses the latest Intelligent Transportation System (ITS) technologies to provide real-time transportation system control, monitoring, and information. The open architecture promotes the growth and the integration of systems from multiple vendors.
