Abstract: Integrated Traffic Data System (ITDS) is a microcomputer-based system designed to allow traffic engineers to store, maintain and update traffic network information in a centralized data base. This data base can then be used to create input data files for some of the widely used traffic simulation and network signal timing optimization models. This paper describes the evolution of ITDS, the current status of the system, and the development activity currently underway.
