Urban Travel Route and Activity Choice Survey (UTRACS): An Internet-Based Prompted Recall Activity Travel Survey using GPS Data

by Martina Z. Frignani, Joshua Auld, Abolfazl (Kouros) Mohammadian, Chad Williams, and Peter Nelson,

This paper presents the results of an internet-based prompted recall activity-travel survey using GPS data collection combined with a short activity preplanning and scheduling survey. Besides collecting traditional activity-travel diary data, this survey collects basic information about activity planning and scheduling process. Since aging is a growing concern among transportation planners, this survey has a special focus on the elderly population with half of the survey sample consisting of elderly households. Respondents carried a portable GPS device for 14 consecutive days and at the end of each day uploaded the collected data to a website where the activity-travel survey questionnaires were answered. Results indicate that the quality of the data collected is superior, compared to other survey approaches, and that the response rates were satisfactory considering the time commitment involved in participation. The results reinforce previous findings that GPS surveys have an improved ability to capture trips which are frequently underreported and provide valuable data about the activity planning and scheduling process itself. Respondents' feedback on their participation experience, and fatigue and conditioning analysis reveal that this type of survey has a great potential for data collections that last longer than two weeks.
