Research Highlights
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...

Biking and Walking Quality Counts: Using “BikePed Portal” Counts to Develop Data Quality Checks
Nathan McNeil
Kristin Tufte
Cycling and walking are sustainable modes of transportation which improve community livability, but these modes have not been studied with the quantitative rigor applied to motor vehicle travel. This research aims to change that by improving bicycle and pedestrian traffic monitoring data quality. This research will address the question, how can erroneous data best be identified through automated processes? The research team will answer this question by analyzing continuous bicycle and pedest...
