The objective of this project is to design high-level Advanced Traveler Information System (ATIS) architecture geared towards utilizing the existing transportation infrastructure and resources available in New Jersey. This investigation utilized the National ITS System Architecture (NSA) to develop a statewide standard for collecting, processing, and disseminating traffic and transportation information. The information required to create these high-level system architecture diagrams was obtained from a series of surveys and interviews of the major public and private transportation agencies in New Jersey, such as the New Jersey Department of Transportation (NJDOT), TRANSCOM (Transportation Department Coordinating Committee), and the New Jersey Turnpike Authority. The results were incorporated into an agency resource database, which provided a concise, detailed description of each agency assets. Analysis of this database revealed the existing capabilities of each agency, which was used to generate the high-level system architecture. Next, Traveler Information Service Scenarios were generated based on the developed Architecture to determine the effectiveness of the architecture in realistic situations, the role that NJDOT should play in these cases, and future needs of NJDOT in terms of collection, processing, and dissemination. Finally, based on the analysis results, NJDOT was given recommendations on its role in ATIS in New Jersey, both from a financial and operational perspective.
