Capstone students take on transportation challenges

Jun 18, 2014

Five teams of Portland State University seniors worked on projects in the transportation arena, as the final outcome of their Capstone course.

The transportation Capstone projects were completed under the advisement of Dr. Robert Bertini, a professor of Civil and Environmental Engineering at Portland State University and OTREC’s founding director.

Senior Capstone projects in engineering are about more than just technical aspects of design. They are an opportunity for students to meet with clients and consult with professionals, to develop the communication and collaboration skills which will be necessary in future careers.

John Edwards, a student team leader, described the project as a great opportunity. “We learned a great deal about project management and communication in working with professionals,” Edwards said.

In each project, students met with clients under the guidance of faculty to come up with solutions to problems that the clients were facing.

A group led by Krista Hager worked on a concept design for bicycle parking at the Goose Hollow eastbound MAX Station in southwest Portland, Ore.

PSU student team finds transit solutions for Salem-Keizer

Jun 16, 2014

Portland State University students in the Master of Urban and Regional Planning (MURP) program came up with some innovative transit solutions for the Salem-Keizer area, just south of Portland, Ore. in the Willamette Valley.

The Salem-Keizer transit provider, known as Cherriots, requested that a planning group come up with alternative forms of transit that would be a better fit for the study area. MURP students Darwin Moosavi, Brenda Martin, CJ Doxsee, Mike Sellinger, Lauren Wirtis and Matt Berggren took on the challenge as their capstone project.

The bus service currently provided by Salem-Keizer Transit is inefficient in the low-density neighborhoods of West Salem, South Salem, and Keizer. Buses in those neighborhoods often run half-full, or nearly empty, along looping, circuitous roads that lack an interconnected grid pattern.

The student team, Paradigm Planning, proposed a “flexible transit” system which can better serve this type of low-density suburban area.

Fixed-route transit is typical bus service, in which buses come to predefined stops at regularly scheduled intervals. Demand-responsive or paratransit, the opposite extreme, is an on-demand service typically reserved for the elderly or disabled, in which a rider calls to be picked up by a bus at home....

Case studies explore TOD and social equity

Jun 09, 2014

Historically, large-scale transportation infrastructure projects have had devastating outcomes in communities of color. With twentieth-century urban renewal efforts often came the displacement of underprivileged communities, the loss of low-income neighborhoods and their replacement with affluent housing and freeways.

According to new OTREC research from the University of Oregon, transit-oriented development, or TOD, can offer a different trajectory. Rather than displacing residents, TOD has the potential to improve neighborhoods for the benefit of those who live there.

OTREC researcher Gerardo Sandoval grew up near MacArthur park, one of the two sites studied, and has witnessed firsthand the neighborhood’s dramatic change. “I think the coolest thing about MacArthur Park is that now it’s considered a national model for TOD. When I was growing up there … nobody saw it like that. It was thought of more as a low-income area,” Sandoval said.

The project examined two California neighborhoods: MacArthur Park, in Los Angeles, and Fruitvale, in Oakland. In both neighborhoods, the majority of residents are recent immigrants from Mexico and Central America, many of whom have significantly lower incomes and rely heavily on public transportation.

In the last few decades, both sites have seen TOD coincide with neighborhood...

Policymakers meet with youth for discussion on transit justice

May 27, 2014

The Multnomah Youth Commission, or MYC, held its first Youth Summit on Transit Justice on May 17, 2014 at David Douglas High School.

The MYC, a group of young people ages 13-21, plays an advisory role for local government in Multnomah County and the City of Portland.

The summit held on Saturday the 17th was an entirely youth-led event, with members of the MYC meeting at David Douglas at 11 a.m. After they spent the morning organizing their materials and preparing their arguments, they opened the doors for adults.

PSU professor Lisa Bates, who is studying the transit-dependent population for NITC, was in attendance with her capstone students. As part of a capstone course where students are required to conduct research that leads directly into social equity, Bates’ students worked with the youth of the MYC on transit justice. They applied a social science research foundation to their ideas and assisted them with using some best practices in the field.

At 2:30 p.m., transit policymakers and community leaders began to enter the high school. Following a brief introductory presentation, the young people split up the group into breakout sessions.

Rethinking transit-oriented development

Jan 10, 2014

Note: In advance of the Transportation Research Board's annual meeting, the biggest forum on the transportation research calendar, OTREC.us is profiling some of the researchers who will present their work.

In transit-oriented development, planners typically focus on the neighborhood within a quarter of a mile of a transit stop.

Housing and commercial developments within this "walkable zone" are thought to be the ones primarily affected by, or dependent on, the transit stop.

New research from the University of Utah expands the traditional one-quarter-mile distance away from transit stops to a broader radius of about one and one-quarter mile from a stop.

The project's principal investigator, Susan Petheram, led a team of researchers who used the Salt Lake County assessor's database to analyze property values surrounding light rail stops. Petheram is a NITC doctoral dissertation fellow and the research stems from her dissertation.

"We were seeing a certain negative impact [on property values] right around the core station area for single family homes," Petheram said. Slightly...

What if the fare isn't fair? TRB 2014

Jan 06, 2014

Steven Farber, of the University of Utah, is conducting research for the Utah Transit Authority (UTA) surrounding its potential move to a distance-based fare system.

Typically, transit fares are a flat fee based on a given window of time: riders may pay $2.50 to ride anywhere they wish within a two-hour period, for example.

This system can negatively impact low-income populations, who as a general rule tend to travel shorter distances than people in higher income brackets. In a flat fare system, many low-income riders end up subsidizing the longer trips of wealthier riders.

The UTA is considering changing its fares to a distance-based system, wherein riders would pay a fee determined by how far they travel.

Farber, along with co-investigators Keith Bartholomew and Xiao Li of the University of Utah, Antonio Páez of McMaster University, and Khandker M. Nurul Habib of the University of Toronto, conducted a spatial analysis of data from the Utah Household Travel Survey collected in Spring 2012.

They were searching specifically for...

OTREC remembers Nohad A. Toulan

Oct 29, 2013

Nohad Toulan’s influence on Portland State University and the wider community can be seen not only in the school bearing his name, the Nohad A. Toulan School of Urban Studies and Planning, but also in the holistic approach to transportation research and education that would help cement Portland’s innovative reputation and shape its transportation center, OTREC.

Toulan, emertitus dean of the College of Urban and Public Affairs, and his wife, Dirce, both died Monday. He was 81 and she was 78.

Toulan helped pave the way for the creation of OTREC by stressing the value of human development, said Robert Bertini, OTREC’s founding director. “Our focus on emphasizing people, on building and encouraging the development of faculty, students and collaborators outside the university, that was directly influenced by the atmosphere created by Dean Toulan,” Bertini said.

Portland State’s Urban Plaza embodies Toulan’s vision of an urban university connected with its city. There, the college’s lessons spill out into a vibrant plaza interwoven with transit and the life of Portland.

OTREC’s—and Portland State’s—reputation for multidisciplinary, collaborative transportation research grew thanks in part to Toulan’s efforts. Toulan extended Bertini, an engineering professor, a joint appointment the College of Urban and Public Affairs. “He said, ‘I need an engineer in my college,’” Bertini...

OTREC researchers develop livability metrics for public transit

Oct 14, 2013

The U.S. Department of Housing and Urban Development has identified some “livability principles” which include healthy, safe and walkable neighborhoods and safe, reliable and economical transportation choices.

Transit agencies and local governments routinely use metrics to evaluate the performance of transit systems, but a uniform standard of transit data collection does not exist outside of the reporting requirements of the National Transit Database (NTD). Because of the types of data collected for the NTD, the focus of performance measurements is often on ridership and financial performance, leaving aside the question of livability.

In a new project sponsored by OTREC, Principal Investigator Marc Schlossberg, associate professor in the department of planning, public policy and management at the University of Oregon, along with co-investigators Jennifer Dill of Portland State University and Nico Larco, also of the University of Oregon, set out to create a set of tested and refined performance indicators that transit agencies across the nation can use to evaluate and improve their system performance in relation to livability goals.

Traditionally, transit systems are thought of exclusively in their wholeness: how the system serves a region,...

OTREC research looks into bus safety performance monitoring and analysis

Sep 09, 2013

Generally, public transit is safer than other personal travel modes. However, not all transit modes are created equal: compared with other forms of transit, buses have a higher safety incident rate.

For example, while buses in fixed route service accounted for 39% of the transit industry’s passenger miles in 2009, their associated casualty and liability costs accounted for 51% of the industry total. In 2010 TriMet, the Portland, Oregon region’s transit provider, formed a safety task force to review its bus operations.

The task force recommended that TriMet develop a comprehensive performance monitoring program to better integrate safety in its planning practices. Like other urban transit providers, TriMet was already sending safety performance information to the Federal Transit Administration’s National Transit Database. The task force recommended seeking a deeper understanding of the types of incidents that are occurring, and of when, where, and why they occur. The task force also recommended that operators complete a recertification program annually to ensure that safe driving practices remain fresh.

In addition to keeping operators current on their safety training, the annual recertification program presented researchers with a unique opportunity to gain a firsthand perspective of the safety risks that bus operators encounter on a daily basis. Thus a survey of operator...
