Tuesday marks another busy day of lectern and poster presentations at the annual meeting of the Transportation Research Board in Washington, D.C., with presentations from core TREC faculty along with current and former NITC student of the year recipients. The day concludes with the annual NITC reception, which all are welcome to attend. More information on the reception is at bit.ly/nitc-trb2015.

TRB helps mark the 10th anniversary of Portal, TREC's multimodal transportation data archive, with a presentation at 10:15 a.m. in room 151A. Kristin Tufte of Portland State, who manages Portal, presents her paper on the history of the program and some of the ambitious changes it's undergoing. Portal was founded in 2004 by Robert Bertini, who also co-authored the paper with Morgan Harvey. Portal started with a single data source, freeway loop detector, and has grown in ten years to contain freeway data, arterial signal data, travel times from Bluetooth detection systems, transit data and bicycle count data. Portal has also grown geographically, and Tufte will offer examples of how Portal data has been used by regional partners – with a focus on measuring the performance of the multimodal transportation system, but also including educational elements and research.

Sunday, Jan. 11 is workshop day at the annual meeting of the Transportation Research Board in Washington, D.C.

Krista Nordback of TREC presents at the 1:30 p.m. (all times Eastern) workshop "Making Bicycle and Pedestrian Data Programs Count."

Nordback's will offer her portion of the workshop, "Data Sharing: A Count is a Terrible Thing to Waste," with Jeremy Raw of the Federal Highway Administration. The presentation covers the state of the practice for data warehousing of bicycle and pedestrian traffic data. It's in room 150B.

Patrick Singleton of Portland State University presents at a workshop showcasing the work of second- and third-year Eisenhower doctoral fellowship recipients from top universities across the country. Singleton presents "The theory of travel decision-making: A conceptual framework of active travel behavior." The workshop begins at 9 a.m. in Room 202A.

Check out a quick summary of our activities each day at TRB:

Researchers at campuses affiliated with the National Institute for Transportation and Communities, or NITC, will present 86 papers at the annual meeting of the Transportation Research Board of the National Academies. That's a record number for the Portland State University-based university transportation center, dating back to the 2006 founding of OTREC.

The NITC program is led by Portland State with partners University of Oregon, Oregon Institute of Technology, University of Utah and University of South Florida. The five universities had the work of 93 researchers, as author or coauthor, accepted for presentation Jan. 11-15 at the meeting, the preeminent national conference for transportation researchers. Around 12,000 people from around the world are expected to attend.

To present at the TRB meeting, researchers must submit full research papers for peer review. Only around half of the submitted papers are chosen for presentation at the meeting.

The researchers from NITC campuses will present 25...

Despite the many connections between transportation and public health, many agencies tasked with long-range transportation planning have yet to completely consider effects on health, a Portland State University research team found. The research will be presented at the annual meeting of the Transportation Research Board in Washington, D.C. Jan. 11-15.

Patrick Singleton, a Portland State graduate student researcher, will present the paper “Incorporating public health in U.S. long-range metropolitan transportation planning: A review of guidance statements and performance measures,” during a poster session Tuesday. The paper grew out of concepts developed in a Portland State course on transportation and health taught by Prof. Kelly Clifton, who is a coauthor on the paper.

Individually, transportation and public health each have a wealth of research. That research doesn’t always cross over, Singleton said.

“The integration of these disciplines is in its infancy,” he said.

If transportation planning agencies were to fully consider transportation and health connections, those considerations would show up in their long-term plans, the research team reasoned. Performance measures would point to the potential effects of a health focus.

The researchers focused...

Bryan Blanc will present findings at TRBA study showing surprisingly high numbers of pedestrians using a congested suburban intersection draws national attention as its researchers present their findings at the annual meeting of the Transportation Research Board Jan. 11-15 in Washington, D.C. The number of pedestrians was recorded, not with a specialized counting machine, but using the technology that was already in place at the intersection.

Knowing how many travelers use a transportation system is important for a number of reasons. Engineers and planners need to be able to estimate travel demand, and to do so they typically count the vehicles. Annual average daily traffic (AADT) counts have been collected for decades in the United States. 

In recent years the demand has increased for non-motorized counts. For a multi-modal transportation system it is just as essential to know the number of road users who aren’t in vehicles, but traveling by bicycle or on foot. This research offers DOTs an approach for counting these travelers that doesn’t require...

Liming WangTransportation Cost Index: A Comprehensive Performance Measure for Transportation and Land Use Systems and its Application in OR, FL, and UT” is a Portland State University research project that will be presented at the 2015 annual meeting of the Transportation Research Board.

Portland State University researchers Liming Wang and Jenny Liu are developing a comprehensive performance measure that enables planners and the public to evaluate the performance of transportation and land use systems over time and across geographic areas.

Transportation engineers have a long history of using performance measures such as the Highway Performance Monitoring System (HPMS) to evaluate the operation of the transportation system. Traditionally, such measures heavily focus on the traffic condition, especially for drivers. 

Since the last decade, especially with the...

Toward a Spatial-Temporal Measure of Land Use Mix 

Summary: Urban policies have emphasized the importance of mixing land uses in a neighborhood as an intervention beholding of lasting planning and public health benefits. Transportation planning research has identified the potential of efficiency gains achieved by increasing land use mix and the subsequent shortening of trip lengths; whereas, public health research has accredited increased land use mixing as an effective policy for facilitating greater physical activity. However, despite the purported transportation,...
