Abstract: Walking and bicycling are being promoted as transportation options that can increase the livability and sustainability of communities, but the automobile remains the dominant mode of transportation in all United States metropolitan regions. In order to change travel behavior, researchers and practitioners need a greater understanding of the mode choice decision process, especially for walking and bicycling.

This presentation will summarize dissertation research on factors associated with walking and bicycling for routine travel purposes, such as shopping. More than 1,000 retail pharmacy store customers were surveyed in 20 San Francisco Bay Area shopping districts in fall 2009, and 26 follow-up interviews were conducted in spring and summer 2010. Mixed logit models showed that walking was associated with shorter travel distances, higher population densities, more street tree canopy coverage, and greater enjoyment of walking. Bicycling was associated with shorter travel distances, more bicycle facilities, more bicycle parking, and greater enjoyment of bicycling. Respondents were more likely to drive when they perceived a high risk of crime, but automobile use was discouraged by higher employment...

This project will help demonstrate how sustainable ("green") streets contribute to the well-being of a community, including the physical and mental health of older and younger adults, along with the environment and economy. The project will collect data in Portland, OR neighborhoods to answer the following research questions:

Are residents living near sustainable streets more physically active in their neighborhood?

Do residents living near sustainable streets interact with neighbors more and demonstrate higher levels of neighborhood social capital?

What are residents’ opinions of sustainable streets?

Are there variations in responses to sustainable streets by age or other demographics? In particular, how to older adults differ from younger adults?

Does the implementation process and design affect green street outcomes?

Do sustainable streets affect home values?

How do green streets affect stormwater flows, urban heat island, and carbon sequestration in Portland neighborhoods?

The project includes a survey of residents in two neighborhoods with green street features and two control neighborhoods; an environmental assessment of the green street treatments; and an analysis of housing values using a hedonic modeling approach.

The project will be guided by an Advisory council of members of various stakeholder organizations...

Abstract: Transportation planning for the 2010 Olympic Winter Games— Vancouver’s largest special event ever—was a complex challenge compounded by venue security road closures throughout the city. Through public engagement, careful planning and evaluation, and collaboration with transportation partners, the City of Vancouver developed a wide range of innovative strategies to create its Host City Olympic Transportation Plan. By almost every indicator, the transportation operations and transportation demand management (TDM) strategies of the 2010 Olympic Winter Games were an unqualified success. However, the goals of the Host City transportation plan were further verified the Host City Olympic Transportation Plan Downtown Monitoring Study in partnership with the University of British Columbia (UBC) to evaluate the transportation impact of the Games by using in-the-field data collection. The transportation legacy of the Host City Olympic Transportation Plan was a proven example of a large scale travel behaviour shift to sustainable modes, in unprecedented and record numbers.  The experience of the Host City Olympic Transportation Plan demonstrated that residents and businesses can be motivated to take sustainable modes of transportation if convenient alternatives to vehicle travel are available. This presentation will discuss the detailed results of the Host City Olympic Transportation...

Abstract: Urban arterials often represent complex venues of transportation operations, co-mingling non-motorized users with transit services and a wide variety of land uses and traffic patterns. This presentation presents results related to the evaluation of a new Adaptive Traffic Control System (SCATS) on Powell Boulevard in southeast Portland. The presentation will discuss challenges and opportunities associated with the evaluation of new technologies and the development of comprehensive urban arterial performance measures.

The transportation engineering community is advancing methodologies to encourage active transportation. Adoption of new methodologies and standards has not been widely accepted because there remain gaps in the standards by which we determine facilities are adequate, particularly in the development review process. This is highlighted in the vocabulary we use on a daily basis, we continue to consider auto traffic congestion as something that should be reduced, when in reality it can support the encouragement of active transportation. This session will describe these challenges and identify technical procedures that would allow the development of a more balanced transportation system supportive of the local policies of the community. The case study of Portland will be used to describe specific actions where the City has acted consistent with the local policy rather than blindly accepting the national Level of Service thresholds identified in the Highway Capacity Manual.

Topic: Four Types of Cyclists: What do we know and how can it help?

Labeling or categorizing cyclists has been occurring for over a century for a variety of purposes. Dr. Dill's research aimed to examine a typology developed by the City of Portland that includes four categories: Strong and the Fearless, Enthused and Confident, Interested but Concerned, and No Way No How. Unlike several other typologies, this widely referenced typology is intended to apply to all adults, regardless of their current cycling behavior. This seminar will present her findings, focusing on differences between the four types and a better understanding the market for increasing cycling for transportation.

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...

Summary: The declining rates of physical activity among children, particularly adolescent girls, are well-documented, yet there has been insufficient research into the attitudes about health behaviors, particularly active travel, of the children themselves. Tara's research explores attitudes about active transportation among children aged 4-17 years and examines how perceived ability, self-efficacy, and sensitivity to certain environments or facilities vary across gender and age of the children. She utilises data from the Family Activity Study, a multi-year longitudinal intervention study in Portland, ORegon, in which 490 children answered surveys regarding their attitudes, perceptions, and behaviors about traveling by walking, bicycling, or being in a car.

Summary: Urban bicyclists’ uptake of traffic-related air pollution is still not well quantified, due to a lack of direct measurements of uptake and a lack of analysis of the variation in uptake. This paper describes and establishes the feasibility of a novel method for measuring bicyclists’ uptake of volatile organic compounds (VOC) by sampling breath concentrations. Early results from the data set demonstrate the ability of the proposed method to generate findings for transportation analysis, with statistically significant exposure and uptake differences from bicycling on arterial versus bikeway facilities for several traffic-related VOC. These results provide the first empirical evidence that the usage of bikeways (or greenways) by bicyclists within an urban environment can significantly reduce uptake of dangerous traffic-related gas pollutants. Dynamic concentration and respiration data reveal unfavorable correlations from a health impacts perspective, where bicyclists’ respiration and travel time are greater at higher-concentration locations on already high-concentration roadways (arterials).
