Abstract: The Columbia River Crossing (CRC) is a long-term, comprehensive solution to address problems on five miles of Interstate 5 between Portland and Vancouver. The project will replace the I-5 bridge, enhance pedestrian and bicycle paths, extend light rail to Vancouver and improve closely-spaced interchanges. Earlier this year, Oregon Governor John Kitzhaber and Washington Governor Chris Gregoire directed their transportation departments to evaluate three feasible bridge types suggested by an expert bridge review panel - composite deck truss, tied arch and cable-stayed. The seminar presentation includes a general overview of the project, its current status and next steps.

Abstract: This seminar describes the results of a recently completed research project for the Strategic Highway Research Program (SHRP), related to capacity enhancements, as well as ongoing research underway to test the results of this research and to address economic and environmental benefits to progressive approaches to mitigation.
The SHRP 2 CO6 project was designed to provide transportation practitioners with guidance, tools and methods for conducting an integrated transportation planning process - utilizing an ecosystem approach to decision-making that improves and expedites transportation planning and project delivery. To do this, the research team developed a nine-step Integrated Eco-Logical Conservation and Transportation Planning Framework (“the Framework”), that addresses the partnership building as well as the technical and scientific aspects of an this integrated, ecosystem approach to transportation decision making advocated by Eco-Logical: an Ecosystem Approach to Developing Infrastructure Projects, and more recent refinements to watershed permitting and strategic habitat conservation planning.
The seminar will briefly outline the problem statement and the early but critical step of partnership building and process changes. The majority of the talk will focus on utilizing an ecosystem approach to the assessment of cumulative effects and alternatives,...Read more

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...Read more

With the advent of the alternative fuels, it’s very appropriate that gasoline is based on fossil fuels and becoming ancient history. As the gas tax becomes less and less pertinent to adequately funding infrastructure, electronic cashless non-stop tolling options are a more viable solution to financing new projects and providing mobility to existing infrastructure. There are a number of technologies being evaluated for the future; including global position systems (GPS), existing proprietary radio frequency (RF) systems, open standard dedicated open standard dedicated short range communications (DSRC) systems, or the existing cellular networks are also being considered. This presentation will focus on what technologies are available and what emerging technologies are the most likely to emerge as an effective and affordable approach to funding user fees and infrastructure needs. This presentation will also describe how user fees and tolling systems can help the environment, reduce congestion, and provide effective cashless transportation systems based on equitable user fees.
Abstract: Traffic safety engineering continues to rely on the traditional methods of design and operational guidelines, correlated to post-crash outcomes, in an attempt to understand the safety attributes of our roadway system. The recently published Highway Safety Manual provides the newest source of methodologies and statistical models that can be applied to help predict or modify safety outcomes. Additionally, Road Safety Audits are a commonly used practice to gain the insight and experience of traffic and safety experts in an effort to avoid or solve a perplexing and/or unexpected safety problem. Although none of these activities are completely void of human factors considerations, the ability to directly consider driver behavior, driver comprehension, and the impact of driver decision making in the analysis is incredibly complex and often omitted. The use of full-scale driving simulators as a research and analysis tool may help significantly reduce the complexity of human factors-based consideration in the context of safety analyses and provide a new and effective tool to improve the safety of our roadway system. This lecture will consider several safety issues facing transportation agencies, namely median crossover crashes, permissive left-turn crashes, and roundabout safety, presenting thoughts and findings on related research. Additionally, this lecture will integrate the attributes...Read more

Abstract: Portland will soon have three different kinds of car sharing companies: fleet-based (Zipcar), peer to peer (Getaround), and point to point (Car2go). These companies are all seeing very rapid growth, reflecting an explosion of interest car-lite lifestyles that rely on public transit and bicycles for daily commuting complemented by occasional, hourly car rental. Living "car lite" is a growing trend not only in US cities, but also in Europe and Japan. Today's discussion will explore why car sharing is suddenly growing so fast, why venture capitalists, automakers and insurance conglomerates are all paying very close attention -- and investing -- and what this trend could mean for the future of urban living.
Steve Gutmann has been involved in the car sharing industry since 1998, when he was a young car-free banker who needed access to a car to visit clients. He joined Car Sharing Portland that year, took a job at Flexcar a few months later, and eventually became the company's National Sales Manager until Flexcar merged with Zipcar. He has consulted on car sharing for a major European automaker and a top-three insurance company, and he currently works for Getaround, the nation's leading peer to peer car sharing company. He lives in SE Portland with his wife and two young daughters.
Special Seminar: Room 471 Cramer Hall on the Portland State University campus
Abstract: Across the globe wildlife crossings are becoming an accepted mitigation to adapt roads for wildlife movement. With over 800 crossings in the U.S., there are efforts to create new wildlife crossings and retrofit existing structures for wildlife in every state. Science plays a critical role in designing wildlife crossings. Research can show how well different bridge, culvert, and fence designs work at passing wildlife safely under the road, and areas that need adaptive management. This talk will give viewers an overview of wildlife crossings in North America from the speaker's National Academies study, and how research in the western U.S. is helping departments of transportation design, place, and retrofit wildlife crossings that allow multiple species to move under and over roads safely. Dr. Cramer will speak about the ongoing and past wildlife and road studies she has conducted in Utah, Montana, Idaho, Washington, and soon Oregon.
Congressman Earl Blumenauer called together a group of transportation policy makers on Monday, August 4, for a “Rebuilding and Renewing” forum.
Transportation professionals and officials from every level of government, from the federal to the local, met at Portland State University to discuss how to maintain and revive America’s transportation infrastructure.
Blumenauer, the representative for Oregon’s 3rd Congressional District, advocates fuel taxes and VMT taxes to pay for infrastructure needs.
As the Highway Trust Fund rapidly shrinks and America’s deteriorating roads and bridges silently cry out for maintenance, Congress is in the process of trying to determine the best, most sustainable path forward.
During Monday’s forum, a variety of voices were sought out and listened to. Bill Wyatt, executive director of the Port of Portland, gave opening remarks and introduced Blumenauer, who spoke about dwindling highway funds and the need for investment in infrastructure to keep the nation’s economy alive.
He was followed by Tamara Lundgren, CEO of Schnitzer Steel and Chair of the U.S. Chamber of Commerce, who described infrastructure maintenance as both an...Read more
