This two-year project focused on obtaining travel behaviour data that more truly reflected underlying behaviour. In the first year of the project a prototype of REACT!, a web-based, self-administered survey instrument for collecting household travel/activity data was produced. REACT! documents not only the resultant behaviour but also the scheduling process that produces that behaviour by having each respondent record activities as they are initially planned, updated, and executed. In the second year, following a beta test of REACT! and final program modification, a formal REACT! field study was completed for 47 households who used REACT! to provide 24 hours of travel/activity data over a 7 day period. Ensuing analyses focused on the activity scheduling process. All proposed tasks have been successfully completed (although continued development and refinement of REACT! continues). The REACT! software was developed, subject to substantial internal and beta testing, followed by a full field survey. Formal analysis of the resulting REACT! data was completed, with results presented at several conferences and papers being submitted to journals. Results include the identification of distinct spatial and temporal behaviours for planned and unplanned activities, with defined gender differences observed. Classification and structural models were developed to identify regularities in scheduling behaviour. Follow-on research is focused on integrating REACT! with data from TRACER, a GPS-based vehicle tracking system, and extending the range of REACT! project. (Author/publisher)
