This report presents the methodology and results of a study by Kimley-Horn and Associates, Inc. for Arizona’s Transportation Research Center to develop a strategic plan to deploy ITS throughout rural Arizona. This study builds upon ITS strategic plans already completed in Arizona, including the I-40 Corridor, the Phoenix and Tucson metropolitan areas, and a plan for statewide communications. Needs were identified by various stakeholders at Rural ITS Workshops, focus group meetings, and regional Coalition meetings around the state. These needs were then matched, where possible, to one or more of the 36 FHWA User Services defined in the National Program Plan and Advanced Rural Transportation Systems (ARTS) program. Using the National ITS Architecture as a guide, a conceptual system architecture was developed for Arizona, which includes integration with other architectures developed for previous strategic plans in the state. Arizona’s open standards architecture emphasizes interoperability and ease of integration as future market packages come on line in the three deployment timeframes defined for this program. High priority needs identified by stakeholders included traveler information, enhanced emergency services and response in rural areas, increased agency information sharing capabilities, commercial vehicle enhancements, and port of entry efficiencies. Additional long-term needs included advanced in-vehicle technologies (navigation systems, in-vehicle signing, collision avoidance systems), increased roadway safety and emergency systems, and expanded commercial vehicle systems. Project recommendations were developed based on the needs identified by the stakeholders. Deployment timeframes were also defined (1999-2001, 2002- 2007, and 2008-beyond). Cost estimates for technology deployment, operations and maintenance (O&M) over the next 15 years were developed as part of the Strategic Plan. In addition to project recommendations, a preliminary business and management plan was developed stressing the importance of continued Coalition involvement. The report recommends identifying appropriate ITS champions from around the state to provide leadership and continuity for ITS deployment and ongoing O&M activities.

This report presents the results of a study by Kimley-Horn and Associates, Inc. for Arizona's Transportation Research Center to develop a strategic plan to deploy ITS rural technologies along the 1-40 corridor in northern Arizona. The report describes the participation of a coalition of over 100 stakeholders, both in Arizona and from neighboring states (California and New Mexico). The Final Report presents a summary of the findings and recommendations discussed in the fourteen technical memoranda.The needs along the corridor were identified through focus groups meetings of Coalition members. Each of the needs were matched, where possible, to one or more of the 30 FHWA User Services defined in the National Program Plan. A systems architecture, patterned after the ITS National Architecture (April 1996), was developed for the 1-40 corridor representing an evolutionary, open standards architecture that will incorporate specific technologies and Market Packages for each of three deployment time frames. Twenty-one separate Market Packages were incorporated into the architecture in order to respond to the needs identified in this study.A Multimodal 1-40 Traveler Information System is proposed to accumulate and distribute roadway and weather information; transit information; tourism information including national and state park information; incident information; and traveler services information. A request for private partnerships is proposed as a means of deploying the information dissemination systems. Interoperability between Arizona traffic operations centers and communication systems in New Mexico and California is proposed as a goal for ITS deployment in the corridor.

This report documents the work performed on the RHODES Project Phase ll(a). This research effort was the continuation of the RHODES Project Phase I. Phase I explored concepts for models and algorithms for a real time traffic-adaptive control systems for street networks, referred to as the RHODES System. Phase ll(a) focused on further development of some of these algorithms and on performing some preliminary laboratory experiments with these algorithms using simulation models.The control architecture of RHODES is based on a hierarchical decomposition of the overall traffic controlproblem. In an aggregate sense, there are three levels in the control hierarchy: network load control, network flow (platoon) control, and intersection (vehicular) control. RHODES architecture allows for a modular implementation of many of the subsystems within the control structure and the incorporation of IVHS technologies (e.g. new vehicle sensors) when they become available. In Phase ll(a), the decision problems at each of the hierarchical levels were further analyzed and the decision model/algorithm at the intersection level was explicitly formulated, solved, and evaluated using simulation models.
