The Initiative for Bicycle and Pedestrian Innovation hosted its first Webinar Feb. 27, with OTREC researcher Krista Nordback providing an overview of bicycle and pedestrian count programs for the 250-plus registered participants.
The Webinar marks an expansion of IBPI’s professional development offerings, which now also include a sustainable transportation study-abroad program and a wider selection of workshops geared toward transportation professionals and university instructors. Webinar participants were eligible to receive continuing education credits, new this year for IBPI live Webinars and in-person workshops.
While the title of the Webinar, “We are Traffic: Creating Robust Bicycle and Pedestrian Count Programs,” asserts a place for walking and bicycling in traffic discussions, Nordback began with a question: If we really believe that bicycling and walking are modes of traffic, how is that going to change how we measure those modes?
Nordback outlined the Federal Highway Administration’s Traffic Monitoring Guide, published last year. She covered why counting and understanding bicycle and pedestrian...
Read morePortland State University engineering doctoral student Alex Bigazzi has developed a new course aimed at giving transportation engineers experience running emissions models. The course, Transportation Emissions Modeling, is offered through the Department of Civil and Environmental Engineering.
The practical nature of the course sets it apart from the few emissions courses offered at other universities, Bigazzi said. “Those tend to be on the policy side or the environmental side,” he said. “This is unique in trying to help engineers more than policymakers or future policymakers.”
The course fits with both Bigazzi’s own experience and Portland State’s faculty research strength in emissions and modeling. The university already offers an air quality course, but Bigazzi’s offering focuses narrowly on emissions from motor vehicles.
Students spent the first half of the inaugural course learning context for the models, including when they are used and what they can do. “There are federal requirements to do these models for all serious transportation projects,” Bigazzi said. “People need to understand what goes into them and how accurate they can be.”
Because emissions models aren’t as complex...
Read moreThe National Institute for Transportation and Communities, or NITC, program invites proposals for a third round of research, education, and technology transfer projects. The NITC program supports innovations in: livability, incorporating safety and environmental sustainability. This grant is part of the University Transportation Center program, funded by the U.S. Department of Transportation’s Research and Innovative Technology Administration, and is a partnership between Portland State University and the University of Oregon, Oregon Institute of Technology and the University of Utah.
The NITC program will award at least $750,000 in this funding round to research, education and technology transfer projects that support NITC’s theme. Projects should range from $30,000 to $150,000. Projects can focus on research, education, or technology transfer. All projects submitted for this request for proposals (RFP) will undergo peer review. All awards require one-to-one non-federal match in the form of cash or in-kind services from project partners—to include universities, transportation and other public agencies, industry, and nonprofit organizations. Please refer to Section 3 of the linked document below for specific details. Projects awarded under this RFP may start as soon as August 1, 2014 and must be completed by December 31, 2015, including the final report.
Successful research proposals will fit the NITC theme, linking to articulated USDOT priorities:...
Read moreOTREC researcher Miguel Figliozzi details some of the work on an Oregon Department of Transportation project, "Design and Implementation of Pedestrian and Bicycle Specific Data Collection Methods in Oregon," in this video produced by the Federal Highway Administration.
The project reviewed collection methods such as tube counters and loop detectors for accuracy and looked at using count numbers to deterimine average annual pedestrian and bicycle traffic at intersections.
Figliozzi was lead researcher on the project, with Christopher Monsere. Both are associate professors of civil and environmental engineering at Portland State University.
OTREC's Krista Nordback was also involved in the project, as were graduate students Pamela Johnson and Bryan Blanc. More information on the project is at:

Krista Nordback, an OTREC staff researcher, won the Outstanding Paper award from the Transportation Research Board's Bicycle Transportation Committee. The award honors Nordback's paper, "Measuring Traffic Reduction from Bicycle Commuting," which was also featured here:

The paper marked the first research to document a statistically significant drop in motor vehicle traffic during a bike-to-work event. The paper is available to download here or through the link above.
The award is given to the best paper submitted to the Committee on Bicycle Transportation for the 2014 TRB annual meeting, held Jan. 12-16 in Washington, D.C. The committee reviewed 85 papers, using anonymous peer reviewers and committee members.

A new tool added to Portland State University's regional transportation data archive can help transit agencies and riders alike make better decisions. The Portland State-based team presented its work at the Transportation Research Board annual meeting Monday in Washington, D.C.
The team worked with the Portland regional transit agency, TriMet, to make the transit data richer and more useful. Starting with an offline, GIS-based protocol for mapping ridership and service metrics, the team developed an online, interactive map that offers myriad possibilities for users of all types.
Many applications offer schedule data for passengers or operational data for agencies, but none join both types of data in a customizable, Web interface, said project leader Jon Makler. "People would look at this and say, 'It would be amazing if we could put all of this stuff in the same system,'" Makler said. "But they see the work that it requires and they back away."
Here's one way the archive can help transit agencies: Managers receive complaints about bus crowding at certain times on certain routes. They ask an analyst to pull the data, and the analyst returns with a spreadsheet of arcane route and stop numbers. "The managers say, 'That doesn't mean anything to me,'" Makler said.
With the transit archive, those managers can now pull up a route map online and see all the segments that...
Read moreNote: 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...
