The Transportation Research and Education Center (TREC) at Portland State University is home to the National Institute for Transportation and Communities (NITC), the Initiative for Bicycle and Pedestrian Innovation (IBPI), and other transportation programs. TREC produces research and tools for transportation decision makers, develops K-12 curriculum to expand the diversity and capacity of the workforce, and engages students and professionals through education.
Conventional four-step travel demand models are used by nearly all metropolitan planning organizations (MPOs), state departments of transportation, and local planning agencies, as the basis for long-range transportation planning in the United States. A flaw of the four-step model is its relative insensitivity to the so-called D variables. The D variables are characteristics of the built environment that are known to affect travel behavior. The Ds are development density, land use diversity, street network design, destination accessibility, and distance to transit. In this seminar, we will explain how we developed a vehicle ownership model (car shedding model), an intrazonal travel model (internal capture model), and mode choice model that consider all of the D variables based on household travel surveys and built environmental data for 32, 31, and 29 regions, respectively, validates the models, and demonstrates that the models have far better predictive accuracy than Wasatch Front Regional Council (WFRC)/Mountailand Association of Governments’ (MAG) current models.
In this webinar, researchers Reid Ewing and Sadegh Sabouri will demonstrate the effectiveness of the new travel demand model and how to implement it by integrating it into the traditional four-step process.
Friday Transportation Seminars at Portland State University have been a tradition since 2000. You can join us in person at 11:30 AM, or you can also watch online.
The Southwest Corridor Light Rail Project is an expansion of the MAX light rail system into Southwest Portland, Tigard and Tualatin. Not only will the project add 11 miles of light rail track and 13 stations to the system, it also includes new bicycle facilities, sidewalks, safer crossings, improvements to local bus service, and significant upgrades to stormwater treatment infrastructure. As a cooperative effort between regional partners, the project is seen as a catalyst to help realize broader shared goals of fostering equitable communities, ensuring healthy environments, and providing robust mobility options for all modes. Currently in the planning and environmental review process, the project expects to start early construction in 2022 with service beginning in 2027.
This presentation will provide an overview of the partnerships, funding, conceptual design, and benefits of the project. It will explain the project’s guiding principles and walk through how the preliminary designs of station areas, structures, and other key corridor elements help achieve these goals....Read more
This study used a community-engaged interdisciplinary approach to assess the gaps between economic growth and transportation infrastructure development, and the impact of potential gaps on access to opportunities for environmental justice populations within North Central Texas, where population growth has increased over 100% since 2000.
The interdisciplinary team, comprised of social work and civil engineering researchers, in partnership with the regional homeless coalition, measured residents’ perspectives of:
- the economic growth in the area over the past decade,
- the extent to which transportation infrastructure has matched the economic growth, and
- the implications for access to affordable quality housing, employment, quality public education, as well as engagement in cultural and social activities.
The team utilized a mixed-methods (focus groups and survey data), exploratory design to collect responses from a diverse sampling frame. The study results produced an infrastructure profile for the region, in which increased infrastructure from toll ways have improved job and population density, but with major challenges for usage of public transit.
The results can inform public policies that support targeted transportation infrastructure development. Moreover, study results can inform the knowledge base regarding the relationship between economic growth and...Read more
This four-credit (CE 495 / 595) Portland State University course creates an immersive experience to explore the Dutch approach to cycling, transit, innovative mobility and land use. The curriculum will feature material that provides a comparison between U.S. and the Netherlands problems, priorities, and solutions. Specific emphases on planning and engineering principles, policy, and practice will be explored through field trips, tours and guest lectures, while visiting Utrecht, Amsterdam, Delft, and Houten. Students completing this course will develop a broader understanding of sustainable transportation issues and expand their toolkit for context-sensitive solutions. This study abroad program will examines how the urban areas and transportation systems of that nation have been designed to promote transportation by foot, bicycle, and public transportation. You'll learn:
- Design of bikeways, safe pedestrian crossings, and transit systems;
- Urban expansion and land-use policies to promote travel by foot, bike, and public transport;
- Smart cities programs and projects;
- Roadway system design for safety and to prevent roads from becoming barriers to walking and cycling;
- and design for transit priority on roadways and for high-quality rail, tram, and bus service.
- No previous language study required.
Practitioners are invited to attend this one-week, 36-credit study abroad course biking in the Netherlands. Curriculum will compare U.S. and Netherlands problems, priorities and solutions with specific emphasis on design and engineering principles. Leading bicycle professionals responsible for creating and maintaining the Netherlands' world-class bikeway system will teach the Dutch approach to bike and pedestrian planning and design through an intensive week of classroom sessions and tours. The instruction and interaction with other participants will bring you up to speed on innovative practice and research and teach you the skills and techniques you need to start incorporating Dutch principles into your next project, and adapting them for a North American context.
Upon completion of the course, participants will be able to:
- Select the appropriate bicycle facility design based on urban form, traffic conditions and multimodal context
- Identify various options for treating intersections that incorporate bicycle facilities
- Network with international experts from the various facets of bikeway design
- Leverage land uses to better support active transportation
- Feel rejuvenated and excited to go back to work and make an impact!
- No previous language study required.
