Abstract: This article describes the TransGuide advanced traffic management system (ATMS) at San Antonio, TX, USA. Its first phase began in February 1993 and is due to be completed around October 1994. A systems engineering approach was used in its design, with the following system goals: (1) response to accidents and incidents within two minutes; (2) changes to all affected traffic control devices in the system within 15 seconds of identifying an alarm; (3) ability for police officers to send suitable responses from the Operational Control Center; (4) system reliability and expandability; and (5) support for future ATMS and Intelligent Vehicle Highway System (IVHS) activities. After the goals were set, various system architectures and components were evaluated for their ability to meet them. The article describes the technologies adopted, especially for the communications, system software, computer system and network management system. The implementation of the San Antonio ATMS will increase the city's level of transport service, improve its traffic safety, reduce incidents, enhance emergency care response, and reduce vehicle delays. As a result, there will be fewer accidents and casualties, and annual savings of millions of dollars. For the covering abstract see IRRD 867908.
