A field that might play an important role in the future of travel demand analysis and modeling is time use research, although some issues need to be resolved. One such issue deals with the data collection procedure. To provide guidelines to researchers, the strengths and weaknesses of three data collection systems are reviewed. One system relied on the traditional paper-and pencil diary; another system was a self-administreed electronic diary (computer-assisted self-interview, or CASI), and the third was based on an interviewer-administered electronic procedure (computer-assisted telephone interview, or CATI). These systems are compared in terms of the validity of the time use statistics, the unit response rate, and time involved in conducting the survey. The results show that none of the data collection systems is best in all aspects: the unit response rate is highest in CATI, and the time to conduct the survey is lowest in CASI. As far as the validity is concerned, one method was not found to be best for all activities. The comparison clearly shows that relatively large differences exist among the procedures. Consequently one must be careful using the results of studies that are based on different data collection systems. One specific activity that is of increasing interest to policy makers, that is travel, is illustrated.
