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...

Abstract: Reliance on the automobile for most trips contributes to costly trends like pollution, oil dependence, congestion, and obesity. Germany and the U.S. have among the highest motorization rates in the world. Yet Germans make a four times higher share of trips by foot, bike, and public transport and drive for a 25 percent lower share of trips.
This presentation first investigates international trends in daily travel behavior with a focus on Germany and the USA. Next, the presentation examines the transport and land-use policies in Germany over the last 40 years that have encouraged more walking, bicycling, and public transport use. Using a case study of policy changes in the German city of Freiburg, the presentation concludes with policies that are transferable to car-oriented countries around the world.
Bio: Ralph Buehler is Assistant Professor of Urban Affairs & Planning and a Faculty Fellow with the Metropolitan Institute at Virginia Tech in Alexandria, VA. Originally from Germany, most of his research has an international comparative perspective, contrasting transport and land-use policies, transport systems, and travel behavior in Western Europe and North America. His research falls into three areas: (1) the influence of transport policy, land use, socio- demographics on travel behavior; (2) bicycling, walking, and public health; and (3) public transport...

Abstract: As part of Clark County Public Health’s Planning Active Walkable Neighborhoods project, a Health Impact Assessment (HIA) was conducted on the county’s Bicycle and Pedestrian Master Plan. A rapid HIA was completed to provide input on the draft plan, and a subsequent comprehensive HIA was designed to evaluate the impacts of final proposals. This presentation will provide an overview of the process and results of the HIA, examine lessons learned, and discuss transferability to other jurisdictions or projects.

Read moreThis 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?

In the U.S., women are far less likely to bicycle for transportation than men. Explanations include, among others, safety concerns (traffic and crime), complex travel patterns related to household responsibilities, time constraints, lack of facilities that feel safe, and attitudes. This talk will explore how this gender gap emerges in childhood, using data from the Family Activity Study. The study collected data from 300 Portland families (parents and children) over two years, allowing us to see how things change over time.
Jennifer Dill is a Portland State University professor and the director of TREC. She teaches courses in transportation policy, pedestrian and bicycle planning, and research methods. Her research interests focus on the interactions of transportation planning, travel behavior, health, the environment and land use. In general, she is interested in answering these questions: How do people make their travel and location decisions? How do those decisions impact the environment? How do our planning decisions impact people's travel and location decisions? Prior to entering academia, she worked as an environmental and transportation planner.
