Abstract:In 1996, the Federal Highway Administration awarded a Model Deployment Initiative grant to the Phoenix Metropolitan Area to assist in the deployment and integration of a model Intelligent Transportation System (ITS). Using funding from both the federal grant and the project partners, a joint public and private partnership worked together under the name AZTech™ to deploy and integrate ITS and provide real time travel information to the public. The AZTech™ project, in addition to the Arizona Department of Transportation (ADOT) Freeway Management System, local cities, fire, police, emergency management and city development services, has been generating data that are relevant to the transportation community. Not all of these data are currently being archived nor are they readily available to planners and many other potential end users. Realizing the need to capture data available though ITS infrastructure, the Maricopa County Department of Transportation (MCDOT) developed the Scalable AZTech™ Data Server Enhancements for Planning and Operations Project. The enhancements will allow data that is currently collected on the AZTech™ data server to be archived. The archived data will then be made available to local agencies for such uses as planning, modeling, or any other need that exists. For the purpose of this study, the enhancements planned for the AZTech™ data server will be referred to as the Regional Archived ITS Data Server (RADS). The long-term goal of the RADS project is to implement hardware and software for storing both AZTech™ and other data as they come on-line, and allow for the data to be accessed, shared, and utilized. All work completed as part of this project will be consistent with the National ITS Architecture. The implementation phase of this project was recommended by the Maricopa Association of Governments (MAG) ITS Committee for inclusion in the region's Transportation Improvement Program and is currently programmed for FY 2000 with federal CMAQ funds. In order to properly plan for and design the data server, MCDOT contracted with the firm of Kimley-Horn and Associates, Inc. to conduct a User Services Requirements Study to determine the need for archived data in Maricopa County. The study solicited input from a variety of stakeholders throughout Maricopa County to determine the usefulness of the AZTech™ data to their agencies, as well as their need for additional data not currently available through the AZTech™ server. The data that stakeholders currently archive and the need for additional archived data was documented. The results of the study include comprehensive lists of all archived ITS data needs of the stakeholders in Maricopa County, ranked by various categories. These lists can be used to as a tool to help define the inputs, size, and architecture for the RADS. The User Services Requirements Study is the first phase in a multi-phase project to design, build, and deploy the RADS.
