Rick Krochalis, Federal Transit Administration (FTA) Region X Administrator, recently kicked off the Center for Transportation Seminar Series on January 8th with a presentation on the Regional Implications of the Federal Livability Initiative. The presentation touched on the federal interagency partnership in addition to FTA’s involvement in the effort. Smart growth and transit-oriented development are not new concepts. With growing congestion, energy use, greenhouse gas emissions, needs for maintaining a state of good repair on existing transportation systems in addition to a growing and aging and population in the United States; transit is playing a key role in helping address these issues.The seminar was followed with with a roundtable group discussion with TriMet and local partners; and meeting with faculty and students highlighting transit-related research. You can download the podcast or view the seminar if you missed the presentation. Livability is also the theme for the winter transportation seminar series.
Secretary of Transportation Ray LaHood proclaims “Portland is the transportation capital of the United States…” as part of his speech unveiling the Portland-made streetcar, the first to be built in the US in nearly 60 years. OTREC staff were present to witness this historic moment for Portland, in addition to having the opportunity to meet and talk with other leaders in transportation from Oregon.

Northeastern Universityís Peter Furth is known equally for his research in public transportation, bike planning and traffic signals. Furth brings his diverse interests to Portland for the holiday-shortened week of May 25th. On Tuesday, 5/26, there will be a seminar on his traffic signal priority work and on Wednesday, 5/27, there will be another seminar on his work regarding cycle tracks. In addition, Furth will have a variety of meetings with local transportation practitioners, including a bike tour by staff from the Portland Bureau of Transportation. The visit is co-sponsored by OTREC and IBPI. For more information about the seminars, visit PSU's Center for Transportation Studies.
Dr. Brian Taylor, Professor in Urban Planning and Director of the Institute of Transportation Studies at UCLA, was the guest speaker and OTREC Visiting Scholar for the CTS Transportation Seminar on November 16, 2007. Dr. Taylor presented "Transit’s Dirty Little Secret: Analyzing Patterns of Transit Use." Later in the day, he was also the keynote speaker at the fall TransNow Student Conference at PSU, presenting "Rethinking Congestion" to the group of students from around the northwest. Professor Taylor’s research centers around transportation policy and planning. In particular, his work explores how society pays for transportation systems and how these systems in turn serve the needs of people who have low levels of mobility.

Topic: Using "big data" for transportation analysis: A case study of the LA Metro Expo Line
Summary: Access to a comprehensive historical archive of real-time, multi-modal multi-agency transportation system data has provided a unique opportunity to demonstrate how “big data” can be used for policy analysis, and to offer new insights for planning scholarship and practice. We illustrate with a case study of a new rail transit line. We use transit, freeway, and arterial data of high spatial and temporal resolution to examine transportation system performance impacts of the Exposition (Expo) light rail line (Phase 1) in Los Angeles. Using a quasi-experimental research design, we explore whether the Expo Line has had a significant impact on transit ridership, freeway traffic, and arterial traffic within the corridor it serves. Our results suggest a net increase in transit ridership, but few effects on traffic system performance. Given the latent travel demand in this heavily congested corridor, results are consistent with expectations. The benefits of rail transit investments are in increasing transit accessibility and person throughput within high-demand corridors; effects on roadway traffic are small and localized.

Special Transportation Seminar:
Join us for a presentation by Projjal Dutta, NY Metropolitan Transportation Authority’s first-ever Director, Sustainability. He tries to reduce MTA’s environmental footprint and quantify carbon benefits that accrue to the region from transit. This unrecognized service, if priced, can generate substantial resources for transit.

Transportation mode choice is often expressed in terms of models which assume rational choice; psychological case studies of mode adoption are comparatively rare. We present findings from a study of the psychology of adoption for sustainable transportation modes such as bicycles, car sharing, and mass transit. Case studies were conducted with current and former participants in PSU’s ‘Passport Plus’ transit pass program, as well as a longitudinal cohort study of first-time winter bicycle commuters. Composite sequence analysis was used to construct a theory of the adoption process for these modes. Our findings suggest that mode evaluation is cognitively distinct from mode selection and has different information requirements. We conclude that public and private organizations could improve the adoption rate for these modes by tailoring their communication strategies to match the commuter’s stage of adoption.

WEBINAR SUMMARY
Traditionally the discussion about affordability has focused on housing, but HUD’s Location Affordability Index (LAI), released in 2012, helped to elevate the conversation by expanding the focus to include households’ transportation costs. In the...

OVERVIEW
Transportation and land use planning, as a field, is shifting away from segregated uses connected by highways and streets to more compact, mixed-use developments connected by high-quality transit. This new paradigm has brought special attention to transit-oriented developments (TOD), which are sometimes touted as being among the most affordable, efficient places to live. But how affordable are they, and who has the power to effect change? This study examines housing costs for households living in TODs.
KEY LEARNING OUTCOMES
- Learn how many TODs there are currently in the U.S. and what methodology was used to identify them.
- Learn what share of housing in TODs is affordable, what are the relative shares of designated versus naturally occurring affordable units and whether the level of affordability is the same for families of different sizes.
- Learn ...

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...
