Abstract:Many transportation professionals have suggested that improved ATIS data fusion techniques and processing will improve the overall quality, timeliness, and usefulness of traveler information. The purpose of this study was four fold. First, conduct a literature review of the ATIS and data fusion fields in order to summarize current ATIS data fusion practices. The review also included an examination of relevant field case studies and discussions with selected ATIS practitioners to determine the extent and direction of their data fusion interests and applications. Second, develop an appropriate ATIS data fusion model and guidelines to enable a multitude of source data to be fused to create ATIS products and services, consistent with the National ITS Architecture. Third, identify appropriate metrics that describe quantitatively and qualitatively how data quality can be verified, modeled, and processed so that traveler information products can be considered more reliable and useful. Fourth, provide general guidelines on the development of an ATIS data fusion system. This report is intended for surface transportation professionals who have an interest in the planning and deployment of ATIS data fusion systems.
