INFORMATION REQUIREMENTS FOR AN INTEGRATED TRANSIT/TRAFFIC MANAGEMENT AND TRAVELER INFORMATION SYSTEM

This paper documents the assessment of the information requirements for the development of an Integrated Transit/Traffic Management and Traveler Information System. The identification of information requirements represents one of several phases of the information gathering process which was necessary to evaluate the suitability of available technologies, IVHS elements, and architectures for the design of an operational test of the integration of transit and traffic management and traveler information system. The integration design includes the automated transfer of operations and management information between agencies and to the public in order to realize efficiencies in the transportation network. The paper details the information requirements of three public agencies involved in transportation management together with transportation information requirements of the traveling public. Availability of the required data is assessed and existing and potential data sources are identified.
