ITS Data Management System: Year One Activities (0-1752-2)

This report documents research conducted in the development of an ITS data management system, hereafter referred to as "ITS DataLink." The objective of the ITS DataLink system is to retain, manage, share, and analyze ITS data for a variety of transportation analyses. A survey of selected traffic management centers found a number of issues related to the retention and sharing of ITS data, including institutional communication and data management issues. Initial sections of this report include these and other survey findings. Background information is also provided on the definition and selection of transportation performance measures.|Later sections of this report contain specific information on the development of the ITS DataLink system. Based upon the literature review, the report summarizes applicable performance measures that can easily be calculated with ITS data. The report includes examples of performance measure calculation using ITS data from the TransGuide center in San Antonio, Texas. The report documents the desirable features of an ITS data management system. The final sections of the report contain documentation of the web browser-based ITS DataLink system, which has been undergoing online testing and refinement since early 1997. The report concludes with findings on ITS data management systems and contains recommendations for future refinements of the ITS DataLink system.
