SYMPOSIUM ON INTEGRATED TRAFFIC MANAGEMENT SYSTEMS, IRVINE, CALIFORNIA, JUNE 24-26, 1992: APPENDIX A: ITMS WHITE PAPERS; INTEGRATED TRAFFIC MANAGEMENT SYSTEMS

Traffic management systems within the United States are, for the most part, operated and maintained by individual agencies. Freeway control systems are operated by state DOTs, and traffic signal systems in urban areas are operated by cities and counties. Benefits have been obtained from these systems. Additional benefits beyond those obtainable from individual systems can be achieved by integrating them as traffic management systems. This paper shows the need for integrated traffic management systems, outlines the elements that must be included, and provides guidance in developing such a system.
