These are instances of “the positive utility of travel” (PUT). In this dissertation, I conceptually and empirically investigate PUT, its determinants, and its impacts on travel behavio...

Bicycling is enjoying a surge in popularity across the USA but bicycle safety continues to remain a challenge. Cyclists (and pedestrians) are the most vulnerable road users since cyclist-vehicle collisions often result in severe injuries and have high fatality rates with respect to other types of collisions. In particular, intersections are one of the most critical areas in a road network given the high number of conflicts and accidents occurring at these locations.
