    Smartphone-Based Travel Experience Sampling and Behavior Intervention among Young Adults

    This research project aims to develop a data collection application that enables real-time tracking and reporting of the health-related impacts of travel behavior. Using computing, communication, and sensing capabilities of smartphones, an Android phone application—named UbiActive—was developed to collect real-time travel-related physical activity and psychological well-being data from phone users. The application was tested on multiple Android phones, among which Nexus S and HTC Magic were found to produce comparable physical activity outputs with the commercially available accelerometer. The application was further tested in a three-week field study for its viability for real-time data collection and behavior intervention against unhealthy travel behavior. Twenty-three young adults were recruited and randomized into intervention and control groups. Both groups were asked to install UbiActive on their phone and wear their phone on their right hip during all waking hours for three consecutive weeks. The intervention group was provided information on impacts of their travel behavior on physical activity and psychological well-being. No information was provided to the control group. After the field study, all participants were asked to complete a web-based exit survey that was comprised of questions about their general participation experience and specific concerns about the study design, application, compliance requirements, and privacy issues. Findings from the field study show that UbiActive has high potential in collecting travel-related physical activity and psychological experience data, but limited effectiveness in behavior intervention. Findings from the exit survey provide useful insights into potential improvement areas of the study and the UbiActive application.

    Social Networks and ICT in Location Choice
    (University of Minnesota Center for Transportation Studies, 2009-08) Tilahun, Nebiyou; Levinson, David
    Humans are social animals. We routinely interact with others learning about one another, about places, where to go and what places to avoid. Our activities are coordinated with others; sometimes because we explicitly seek to physically meet with those we know personally, other times the coordination is systemic because of norms and requirements of when those activities can take place (e.g. shopping when the shops are open etc.). With those personally known, interactions serve to exchange information, form social bonds and to create social support systems. With in the transportation realm, the social dimension comes into play in different ways. Two or more people who want to meet face to face have to select a meeting location and travel to that destination. People can also learn about short-term activity locations, or about residences and workplaces through others and make location decisions based upon them. These two areas of social contacts' influence in the location choice is the topic of this report. The report looks into how job search methods can impact home and work location patterns at the aggregate level. It also investigates the role job search methods and their outcomes play in subsequent relocation and residential location decisions at the individual level. A third element that will be considered is the relationship between home, work and activity locations for social meetings. The roles of social networks are explored in work finding, residential location choice, and choices of meeting locations.
