Speaker: Joseph Broach, Ph.D. Candidate, Portland State University
Topic: Trick or Treatment? Impact of Route-Level Features on Decisions to Walk or Bike
Summary: Some travel routes attract people walking and cycling, while others may scare them away. What features of street environments are most important, and how do available routes affect decisions to bike or walk on a specific trip? 

Research to date has focused on either large-scale areal measures like "miles of bike lane nearby" or else has considered only shortest path routes. Neither method is suited to capturing the impact of targeted route-level policies like neighborhood greenways. This session will present a new technique for measuring bike and walk accessibility along the most likely route for a given trip. The method is applied to travel data, and results provide new insight into the relationship between route quality and travel mode choice.

Summary: Although the running of red lights is perceived by motorists as a commonplace behavior for cyclists, little research has been done on the actual rates of cyclist compliance at signalized intersections. Furthermore, little is known about the factors that influence cyclist non-compliance. This research seeks to illuminate the rates of and reasons for infringement against red lights using video footage and survey data from cyclists in Oregon. 

Bio: Sam became interested in transportation and planning while studying abroad in Freiburg im Breisgau, Germany. After benefiting from the efficient transit service and excellent walkability there, he came back to the states with a gusto for safe, efficient, and environmentally sustainable transportation. After finally figuring out what to do with his Civil Engineering degree, he enrolled in Portland State. Sam's research interests include cyclist behavior and the comprehension and safety implications of new infrastructure. Originally hailing from Kansas, he has grown weary of Wizard of Oz jokes but is otherwise happy to call Portland his home, especially with the abundance of good coffee, micro brews, and stellar pie that PDX has to offer.

Abstract: City of Davis Bicycle and Pedestrian Coordinator Tara Goddard recently visited Sangju, South Korea as part of a "sister city" delegation. Sangju is the "Bike City" of Korea, with a bicycle mode share approximately that of Davis and Portland combined. Tara will share photos and lessons learned from that trip, compare the bicycle facilities of Sangju with that of Davis and Portland, and discuss opportunities for future bicycle research in East Asia.
