Sponsorship: An FHWA-sponsored Peer Exchange and CSISS Specialist Meeting.
Background and Purpose
Currently, many planning agencies are viewing activity and tour-based models as desirable and feasible techniques for their transportation modeling practices. The development and implementation of activity, tour-based, and micro-simulation modeling approaches, however, require additional and more specialized data on travel activity patterns. One source of data are GPS traces over longer periods, e.g., 12 months of data, compared to a one-day travel diary, we can use this information to analyze personal space-time prisms. We can also look at where people travel on a regular basis compared to places visited infrequently, and examine the time they travel in relationship to the locations they travel, and if they shift their travel times much or not. This type of data will be invaluable as travel demand modeling shifts toward microsimulation. The intent of this meeting is to develop a Peer Exchange and assemble experts to discuss potential approaches on using GPS vehicle traces for defining space-time paths and prisms to be used in activity modeling and microsimulation for transportation analysis. Geographers, planners, and engineers are meeting to discuss different approaches to analyze data of this type and to develop research statements for funding by a variety of public agencies and private companies.
