The city of Portland is using research and expertise from TREC researchers to change how it calculates fees for new development. Developers pay the fees, called transportation system development charges, to offset some of the costs of providing transportation infrastructure.
 
The foundation for those fees has been cars: that is, how many car trips a development will generate. In December, the Portland City Council voted to instead use “person trips” as the basis for those fees.
 
Researchers Kelly Clifton and Kristina Currans have assembled an impressive portfolio of research projects on trip generation. Their research caught the attention of city officials, who brought Clifton and Currans in as consultants to help them rethink the way they assess new fees for development.
 
Their work found a receptive audience of practitioners at TREC’s flagship conference, the Transportation and Communities Summit, last fall. Clifton and Currans held a workshop on improving trip generation methods to better represent the mix of modes found in livable communities. That led to a collaboration with transportation consultants...

A new NITC report offers a multimodal framework for transportation impact analysis – a welcome tool for professionals in many cities seeking more detailed data about non-drivers.

Improving Trip Generation Methods for Livable Communities, a research project headed by Kelly Clifton of Portland State University and Nico Larco of the University of Oregon, is the latest effort in an ongoing collaboration to create more open sourced, widely available data about non-motorized road users.

Over the last decades, cities have become more invested in fostering the conditions to support walking, biking and public transit.

The land development process presents a unique challenge.

Prior to a zoning change or new development, someone has to determine what its impact on the transportation system will be, and whether upgrades will be necessary to accommodate travelers to the new destination. Trip generation is the first step in the conventional transportation forecasting process.

Current trip generation methods used by engineers across the country tend to focus on motorized modes.

Without reliable trip generation rates for anyone but drivers, the transportation impact is difficult to predict. Certain land uses will draw far more walkers,...

Oregon State University’s student ITE chapter is the reigning Western District ITE chapter after taking the Student Chapter Award at the district’s annual meeting in Anchorage, Alaska. The award honors the outstanding chapter for the entire 13-state region, which encompasses 34 student chapters.

The award marks a quick turnaround for a chapter that was dormant a few years ago. Faculty adviser Karen Dixon restarted the chapter when she arrived at Oregon State in 2005. “Another professor, David Hurwitz, came from an active chapter and shared insights he had as a student,” Dixon said. “That helped give us that push.”

Applying for the honor requires a thorough accounting of all the chapter’s activities, Dixon said. “You have to document every tiny thing.”

And having a lot to document was one of the reasons Oregon State won the award, said student chapter President Lacy Brown. “We did a lot of activities out in the community,” Brown said. “A lot of outreach to other students on campus who weren’t necessarily in our chapter.”

The chapter brought in speakers from private consultants and public agencies, took field trips across the state and attended conferences in the Northwest and beyond, including the Transportation Research Board...

Over 60 students from eight universities around the northwest visited PSU on November 16 to participate in a transportation research conference organized by and for students. Following a welcome breakfast, a panel consisting of representatives from TriMet, CH2M Hill, Port of Portland and Kittelson & Associates discussed “big picture” transportation issues with students. Ten students gave presentations about research or practice, and many of the students presented posters. The conference concluded with a keynote address from Professor Brian Taylor from UCLA on the topic of “Rethinking Congestion.” Many of the students who arrived the evening before also participated in the Oregon Section ITE Traffic Bowl at McMenamins Edgefield. Thank you to graduate student Oren Eshel, who led the conference organization and did an outstanding job.
