INTEGRATED SYSTEM ARCHITECTURE AND REAL-TIME DATA INTERCHANGE BETWEEN PUBLIC TRANSIT AND INTELLIGENT TRANSPORTATION SYSTEM SERVICES

This paper describes how the Houston METRO Regional Computerized Traffic Signal System (RCTSS) and the METRO Public Transit System (MPTS) are being integrated into a common systems architecture with real-time interoperability. RCTSS is also integrated with the TxDOT, Houston District, Metropolitan Regional Freeway Management System. This totally integrated, county-wide system provides over 1,800 square miles of real-time coordination between transit and traffic functions. Brief details are provided of: a) the integrated communications network; and b) the operation centre architecture. For the covering abstract see IRRD 868006.
