Abstract: In transportation planning and engineering, market segments or groups of individuals with varying attitudes and travel behavior are often identified in order to define a set of policies and strategies targeted at each segment. Examples include residential location choice studies, electric vehicle adoption and the marketing of public transit options. Defining market segments is common in the marketing literature, typically based on observed socioeconomic characteristics, such as gender and income. However, in addition to these characteristics, travelers may also be segmented based on variations in their observed travel and activity patterns. The activity-based approach to travel demand analysis acknowledges the need to analyze the travel patterns of individuals, conceptualized as a trip chain or tour, as opposed to individual trip segments. This has implications for identifying markets segments based on travel patterns which needs to distinguish between the sequencing and timing of travel choices and activities, in addition to the actual travel choices and activities. One approach that holds promise is pattern recognition theory which has wide applications in image analysis, speech recognition and physiological signal processing. In this study, pattern recognition methods are applied to observed daily travel and activity patterns from Oregon to identify travel market...

Adam Moore: Bus Stop Air Quality: An Empirical Analysis of Exposure to Particulate Matter at Bus Stop Shelters

Congested traffic corridors in dense urban areas are key contributors to the degradation of urban air quality. While waiting at bus stops, transit patrons may be exposed to greater amounts of vehicle-based pollution, including particulate matter, due to their proximity to the roadway. Current guidelines for the location and design of bus stops do not take into account air quality or exposure considerations. This study compares the exposure of transit riders waiting at three-sided bus stop shelters that either: 1) face the roadway traffic or 2) face away from the roadway traffic. Shelters were instrumented with air quality monitoring equipment, sonic anemometers, and vehicle counters. Data were collected for two days at three shelters during both the morning and afternoon peak periods. Bus shelter orientation is found to significantly affect concentration of four sizes of particulate matter: ultrafine particles, PM1, PM2.5, and PM10. Shelters with an opening oriented towards the roadway were consistently observed to have higher concentrations inside the shelter than outside the shelter. In contrast, shelters oriented away from the roadway were observed to have lower concentrations inside the shelter than outside the shelter. The differences in particulate matter...

Abstract: The historic divide between spacial planning and transport planning has caused many crucial insights to remain stuck on one side of the divide. When dealing with public transit, Jarrett Walker argues that planners urgently need a clearer view of transit's fundamentals. These are often lost track of amid the excitement of a particular project, resulting in development where efficient (and therefore abundant) transit is impossible. This talk reviews the much-ignored principles of efficient transit networks, bus or rail, and argues that true "transit-oriented development" must be consist with those principles. These principles yield surprising conclusions both about many New Urbanist projects, and also about the potential of 82nd Avenue and similar "sprawl arterials."

Speaker Bio: Jarrett Walker is an international consultant in public transit network design and policy.  He has been a full-time consultant since 1991 and has led numerous major planning projects in North America, Australia, and New Zealand.  He currently serves as a Principal Consultant with MRCagney based in Australia.  He provides expert advice to clients worldwide

Abstract: Portland is planning to launch a bike share system. Bike share is a new form of public transit that is rapidly spreading through the United States. In 2009, bike share operated in two U.S. cities. Today, 20 US cities operate systems with another 15 in the planning stages. In several cities, including Denver, Minneapolis and Washington, DC bike share has demonstrated the ability to bring new people to bicycling while reducing single occupancy vehicle trips. How will bike share work in the nation’s most bike friendly city (doesn’t everybody already have a bike)? What challenges does Portland face, and what opportunities does bike share offer to reach the Portland’s Bike Plan for 2030’s ambitious goals?

Speaker Bio: Steve Hoyt-McBeth is a project manager in the Portland Bureau of Transportation’s Active Transportation Division. He has worked on bike share at PBOT since 2008. Steve also manages PBOT’s employer and commuter Transportation Demand Management program, SmartTrips Business. He has 15 years experience working with local governments and neighborhoods in Oregon and California on land use, energy and transportation issues. Steve is a graduate of the University of Oregon.

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...
