In recent decades, cities have become increasingly motivated to invest in infrastructure that supports multimodal options like walking, biking and public transit. Trip generation, the first step in conventional four-step forecasting models, is a central figure in determining how those investments are made.
However, when considering pedestrian and bicycling travel, the current practice is usually to either leave those trips out of the model altogether, or to simply present them as a mode choice option that is not analyzed further. In short, they’re car-centric.
Without reliable trip generation rates for anyone but drivers, an accurate transportation impact is difficult to predict. Certain land uses will draw far more walkers, cyclists and transit riders than drivers. Cities lack enough information to strategically plan for multimodal investments.

Addressing Bicycle-Vehicle Conflicts with Alternate Signal Control Strategies -and-
Improving Bicycle Crash Prediction for Urban Road Segments
Sirisha Kothuri, a Portland State University research associate, has recently completed two distinct studies taking different approaches to advancing bicycle safety. Kothuri will lead a Sept. 13 workshop on Bicycle/Pedestrian Focused Signal Timing Strategies along with Peter Koonce, the division manager of Signals & Street Lighting for the City of Portland. The half-day workshop will be part of Transportation and Communities 2018, a two-day intensive training event for transportation professionals.... Read more
Quickly regaining use of a city's transportation system after a major disaster is critical to relief efforts. To help cities recover from emergency situations, TREC is working to develop a transportation recovery plan that includes transit, travel demand management (TDM), social media, and intelligent technologies.
The plan is supported by a research grant awarded to Portland State University by the Federal Transit Administration (FTA), an agency of the U.S. Department of Transportation (U.S. DOT), as part of its Innovative Safety, Resiliency, and All Hazards Emergency Response and Recovery Demonstration program. The project, led by TREC...Read more
If more drivers switched seats to a bicycle, there would be immediate and tangible benefits on the road. Widespread adoption of bike commuting could improve public health through increased physical activity and reduced carbon emissions, as well as ease the burden on congested roads. However different lifestyle demands, physical ableness, and varied topography create an unequal playing field that prevents many from replacing their car trips.
Electric bicycles (e-bikes) are a relatively new mode of transportation that could bridge this gap. If substituted for car use, e-bikes could substantially improve efficiency in the transportation system while creating a more inclusive biking culture for people of all ages and abilities.

Last month, the Transportation Research and Education Center (TREC) hosted a free one-day workshop at Portland State University (PSU) teaching spatial mapping and GIS software to high school girls.
This is the third year that the workshop has been offered in partnership with ChickTech, a nonprofit founded in 2012 to engage women of all ages in the technology industry.
Lisa Patterson, TREC's Workforce Development Program Manager, coordinated the event, which was attended by 16 students. She brought with her eleven volunteer instructors, including PSU students as well as professionals from ChickTech, Angelo Planning, the PSU Bike Hub, and the City of Vancouver, Washington. Her goal was to give the students a unique educational experience with the dedicated attention from so many seasoned instructors.Read more
At the National Bike Summit, U. S. Secretary of Transportation Elaine Chao announced the publication of the Federal Highway Administration’s new resource on Measuring Multimodal Network Connectivity. The guidebook focuses on pedestrian and bicycle network connectivity and provides information on incorporating connectivity measures into state, metropolitan, and local transportation planning processes. Alta, in partnership with ...Read more
Four Portland State University graduate students received Eisenhower Fellowships presented by the U.S. Department of Transportation at this year's annual meeting of the Transportation Research Board (TRB): David R. Soto Padín, Travis Glick, Gregory Norton and Jael Wettach-Glosser are all civil engineering students in the Maseeh College of Engineering & Computer Science at Portland State University.
David Soto Padín, current President of Students in Transportation Engineering and Planning (STEP) at PSU, presented his research in a poster, "Bikeshare + Transit Integration: Best Practices for Increasing Ridership (PDF)," during TRB's Eisenhower Fellowship poster session. He will be working on researching bike share as a "last mile" mode choice for rail rapid transit in the American context. He also presented research on bicyclist positioning behavior at signalized...Read more
This summer we're hosting three workshops through our program, the Initiative for Bicycle and Pedestrian Innovation (IBPI).
These are small group (20 - 25), hands-on, multi-day workshops taught by local experts from the Portland Bureau of Transportation (PBOT), Portland State University, Alta Planning + Design, Toole Design Group, Nelson\Nygaard, Washington County, and more.
A limited number of scholarships are available to help offset the costs of travel and registration. Scholarship applications will be accepted on a rolling basis for the June faculty workshop, so apply early! Scholarship applications for the two August workshops are due by Friday, April 6.
June 19–20, 2018 at Portland State University
This two-day course is designed to help transportation planning and engineering faculty integrate a holistic approach to bicycle and...Read more

To help maximize the implementation of U.S. DOT’s commitment to livable communities, the National Institute for Transportation and Communities (NITC) has launched its third round of pooled fund research funding in 2018. Agency partners are invited to submit problem statements by May 15, 2018.
The pooled fund program offers a process by which cities, counties, MPOs and other regional or local agencies can pool relatively small pots of research dollars to then leverage NITC matched funds for a single, collaborative project.
We held an online information session on February 28, 2018. Watch the video to learn more about the funding process, identifying partners, and crafting an effective problem statement:Read more
