• Abstract:
  The research team conducted a survey of travel and activity scheduling behavior to better understand senior ; citizens’ trip chaining behavior in the Chicago metropolitan area’s most populous counties. The team used an ; internet-based, prompted recall activity-travel survey using Global Positioning System (GPS) devices to collect ; activity-travel diaries and other necessary information. This survey was conducted with 112 people living in 101 ; households in Northeastern Illinois’ Cook, DuPage, Lake, and Will Counties. Because aging is a growing ; concern among transportation planners, this survey focused especially on the elderly population, with ; approximately half of the survey sample consisting of elderly households and the remainder of non-elderly ; households. Each respondent within these households was asked to carry a portable GPS device ideally for 14 ; consecutive days and upload the collected data to a website at the end of each day to fill in their activity-travel ; survey questionnaires. The results suggest that GPS surveys have an improved ability to capture trips that are ; frequently under-reported; the use of prompted recall provides valuable data about the activity planning and ; scheduling process itself, which is not found in traditional surveys. Analysis of the decision-making process ; from the collected data reveals that some aspects of elderly travel behavior are intrinsically distinct from those ; of the younger population. Results indicate that while age does not affect some aspects of activity-travel ; behavior, it does affect such aspects as planning horizons, trip flexibility, and trip chaining practices. This ; study’s results can therefore be used to plan more efficient transit services targeting senior travelers and may ; help change their attitudes toward public transportation.
