Workshop Synthesis: Conducting Travel Surveys using Portable Devices- Challenges and Research Needs

This workshop examined the range of portable devices, their advantages and limitations in terms of technology, the methodologies to extract useful information for travel behavior analysis from portable device data, and how data from multiple sources may be fused together to obtain the data needed for travel demand modeling. In addition, the workshop identified challenges and the research opportunities ahead. But there was general consensus that the travel data collection field is at an exciting point in its history, with unprecedented opportunities to collect rich travel data at fine resolutions of space and time.
