This Transportation Research Record contains 17 papers of the subject of travel survey methods, information technology, and geospatial data. Specific topics discussed include the following: travel diary surveys; Global Positioning System-based and travel survey-based data; competition between egress transport modes; data quality in travel surveys; enhanced system for link and mode identification for personal travel surveys; video-based automated identification of freeway shoulder events; usage analysis of first-generation intelligent transportation systems data archive; role of metadata in the acceptability of results from models; method for creating a real-time distributed travel history database; integration of geographic information system for transportation with real-time traffic simulation system; impact of hourly measured speed on accident risk in the Netherlands; intelligent transportation system spatial data modeling; transit ridership model; AGORA-C map-based location referencing; heuristic algorithm for solving a multimodal location-based concierge service problem; enhanced roadway geometry data collection using an effective video log image-processing algorithm; and smoothing methods to minimize impact of Global Positioning System random error. The 2006 series of the Transportation Research Record: Journal of the Transportation Research Board consists of approximately 820 papers selected from 2,800 submissions after rigorous peer review. The peer review for each paper published in this volume was coordinated by the sponsoring committee acknowledged at the end of the text; members of the sponsoring committees for the papers in this volume are listed on page II. Many of these papers were presented at the 85th Annual Meeting of the Transportation Research Board in January 2006. (Author/publisher)
