The research project developed and tested a computer system that integrated three existing traffic control systems. These three systems were the traffic signal systems on SR-99 and SR-522 in northern King County, and the freeway ramp metering system on Interstate 5 north of the Seattle central business district (the FLOW system). The project continued work begun in previous WSDOT research, described in the report 'Arterial Control and Integration, Final Report,' 1990. The integration system consists of a single microcomputer that communicates both with the minicomputer that operates the FLOW system and the microcomputers that serve as the operator's control computers for both arterial signal networks. To minimize development effort and costs and to demonstrate the potential for adding integration capabilities to existing traffic control systems, the researchers developed the integration system to rely extensively on the existing control systems' capabilities.
