Research Highlights
Exploring the Use of Crowdsourced Data Sources for Pedestrian Count Estimations
Sirisha Kothuri Nathan McNeil , Kate Hyun , Stephen Mattingly
Counts provide the foundation for measuring nonmotorized travel along a link or a network and are also useful for monitoring trends, planning new infrastructure, and for conducting safety, health, and economic analyses. For safety analysis, they are critical in assessing the exposure to risk. Over the last decade, several automated technologies have been developed to count bicyclists and pedestrians. Despite advances in counting technology, cost and other considerations will continue to limit…

Pedestrian Modeling and Agent Cognition
Nicholas Perdue
Walking is one of the most commonplace forms of human expressions, yet the forms, motivations, and practices of walking vary greatly and are often at odds with dominant discourses in urban and transportation planning. As interest in pedestrianoriented studies continues to grow, there is danger that dominant discourses will continue to reinforce the framing of pedestrians and the practices of walking as slower moving versions of the private automobile and ignore deeply embedded emotional,…
