Social Networks and Travel Behavior: A Comparative Analysis |
摘要: |
Using a comparative approach, this project explores how social networks influence travel behavior at three, large public universities that differ in environmental constraints such as climate, infrastructure and city/university-wide transportation culture. Focus groups and interviews of students and transportation policy decision-makers provide qualitative context for survey design and statistical analysis. Surveys of random samples of students provide measures of mode choice, as well as the "egonetworks" of contacts with whom each respondent communicates about transportation choices. Analysis includes measurement of network structures such as network density and centrality. Discrete choice models are estimated to predict travel mode as a function of individual characteristics as well as social networks attributes. Models from each university are compared to identify environmental factors which affect how social influences impact travel behavior. A key comparative hypothesis is that the influence of social networks is smaller in contexts with greater environmental constraints; high levels of environmental constraints make social networks less relevant. A greater understanding of the social processes that influence travel behavior can help improve policy and education programs designed to increase the use of alternative transportation modes and sustainable transportation behaviors. |
