This paper presents the development of the Traffic Software Integrated System (TSIS) sponsored by the Federal Highway Administration, US, Department of Transportation. TSIS is a comprehensive set of microcomputer programs and models used for the design, test, and analysis of traffic control strategies. The system is composed of an executive software which enables the proper installation of all the component programs, traffic simulation and signal timing optimization programs (referred to as traffic models), pre-processors and post-processors for traffic models, and several utilities which ease the task of using the system by automating the process of loading and retrieving from a microcomputer. The paper is mainly oriented for traffic engineers with little or no computer background. However, some computer related technical information is also provided to assist readers in determining whether or not TSIS will operate on their systems and/or whether or not TSIS will satisfy their needs. The Phase I development of the system was completed and has been released to the US microcomputer software distribution centers at the University of Florida (McTRANS Center) and the University of Kansas (PCtrans Center) for public distribution. Phase I includes analysis tools for surface streets traffic operations. Phase II, currently under development, will incorporate analysis tools for freeways and corridors. (A)
