Summary: Signalized intersections often rely on vehicle detection to determine when to give a green light. The 2009 Manual of Uniform Traffic Control Devices (MUTCD) includes an on-pavement marking and curbside sign that public agencies can use to indicate where cyclists should position themselves while waiting at an intersection. This presentation reviews the effectiveness of current markings, signs, and other methods used to help cyclists properly position themselves over detection.
Stefan Bussey is an undergraduate civil engineering student at Portland State University. He is interested in exploring how road users’ interactions with each other and the built environment affect the efficiency and safety of road networks. He currently works as a civil design intern at Harper Houf Peterson Righellis Inc.

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.

Abstract: Genesis of America's First "Platinum Bike City", Davis CA
Before there was "Portland, Bike City USA" there was "Davis, Bicycle Capital of America."
Davis and Portland are very different places. Portland is big, old, industrial. Davis is small, new, nerdy. Portland has hills and rain. Davis is flat and dry. But they are both places where people bicycle. A lot. Ordinary folks come to these cities and often start riding a bike. Bicycling in Davis began in the 1950s, when it was a tiny city with the UC agricultural campus. As the city grew, citizens demanded bicycle infrastructure. After years of negotiation, city authorities gave in to pressure and instructed their staff to begin providing for bicycles. Everything had to be designed from the ground up. America had very little bike infrastructure, but that didn't stop Davis from trying dozens of different types of lanes, paths, intersection treatments, etc., and devising workable solutions. So workable, in fact, that they became the California standard, and then the American standard. As America was adopting Davis's designs, Davis continued to promote and accomodate bicycling on many levels, and in 1980 28% of the population commuted by bike.
Now, Davis and Portland are both rated "Platinum" cities for bicycling by the League of American Bicyclists. But they're still as different as night and day. Portland...

OVERVIEW
Intelligent transportation systems (ITS) change our communities by improving the safety and convenience of people’s daily mobility. The system relies on multimodal traffic monitoring, that needs to provide reliable, efficient and detailed traffic information for traffic safety and planning. How to reliably and intelligently monitor intersection traffic with multimodal information is one of the most critical topics in intelligent transportation research.
In multimodal traffic monitoring, we gather traffic statistics for distinct transportation modes, such as pedestrians, cars and bicycles, in order to analyze and improve people’s daily mobility in terms of safety and convenience.
In this study, we use a high-resolution millimeter-wave (mmWave) radar sensor to obtain a relatively richer radar point cloud representation for a traffic monitoring scenario. Based on a new...

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.
This seminar will present results from the BikeGPS study that collected data from Portland area bicyclists using GPS technology. The study collected data from over 150 cyclists for seven days each during 2007, resulting in detailed information for over 1,500 bicycle trips throughout the urban area. The GPS data provides detailed information on the amount, location, and speed of bicycle travel and allows us to answer questions about route choice. For example, how much to people ride on roads with bike lanes, on bike boulevards, or paths? Do these patterns vary by gender, age, or other factors?
