Exploring Drivers’ Attitudes and Behaviors toward Bicyclists: The Effect of Explicit and Implicit Attitudes on Self-Reported Safety Behaviors

Tara Goddard
Bicycling in the United States is disproportionately unsafe as a transportation mode. Despite comprising a smaller share roadway users, bicyclists are twelve times more likely to be killed in a traffic crash with a car than car occupants (Pucher and Dijkstra, 2003).

Peak of the Day or the Daily Slog: Commuting and Subjective Well-Being

Oliver Smith
Dissertation Summary: Travel, especially commuting, is an everyday phenomenon for most people. While routine, travel impacts people's moods and emotions and, possibly, overall happiness. This study will examine how different commuting contexts affect people's sense of well-being.
