This report presents the results of a study to develop strategies for the State of Arizona to evolve/develop state-of-the-art communication infrastructure(s) to support Intelligent Transportation System (ITS) deployments to improve the overall level of safety and efficiency of Arizona's highway network. The report reviews the ITS National Plan (3/95) and Arizona's ITS priorities as defined by the study Technical Advisory Committee. The report reviews existing and planned ITS-related systems within Arizona. The Freeway Management System (FMS) in the Phoenix area is a state-of-the art system that includes video surveillance, incident detection, ramp metering, and many other functions. Future major systems being considered include an FMS in Tucson and a rural FMS in Flagstaff for the I-40 corridor. The report recommends an evolution to open standards based communication infrastructure. The report discusses wireline modem technologies, the U.S. digital hierarchy, SONET fiber hierarchy, and multiplexing and EIA-232. A discussion of system level digital communication system design is presented and includes information on ITS data sources. The report concludes with recommendations for statewide, metropolitan area, and rural area communication infrastructure(s) plus other considerations. The report concludes that open standards facilitate modular, expandable, and scaleable communication infrastructures to accommodate the evolutionary nature of ITS service definition(s), benefit validation(s), and deployment(s).
