NCHRP 08-164: Institutional Integration of Active Transportation
Jennifer Dill
John MacArthur , Nathan McNeil
The need for improving active transportation safety and mobility is clear, as the share of all road user deaths that are pedestrians or cyclists has risen nationally. The US Department of Transportation (US DOT), along with state DOTs across the nation, have made addressing this safety challenge a priority, along with reducing emissions and improving health through increasing the use of active transportation for everyday travel. In many cases, solutions are also clear, including improved infr...

Exploring the positive utility of travel and mode choice
Patrick Singleton
Traditionally, travel is considered a disutility to be minimized, and travel demand is derived from activity demand. Recently, scholars have questioned these axioms, noting that some people may like to travel, use travel time productively, find other benefits in traveling, or travel for non-utilitarian reasons. 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...
