These software subsystems include host, plaza, and lane controller software, as well as operating subsystems such as those for revenue management and reconciliation, supervisory functions, and security. SATS represents a new conceptual approach to toll collection system technology and implementation. It is modular, which readily allows portions of the software to be interoperable with non-SATS components, is easily configurable, and is constructed around Microsoft Windows NT software technology. The SATS software is also scaleable, which means it can be effectively used to serve customers with two to four toll lanes at a single plaza or for customers with hundreds of toll lanes and dozens of toll plazas.
