Higher Speed Limits Lead to Increase in Serious Crashes in Eastern Oregon

Speed limits on approximately 1,400 miles of highways and interstates in Eastern Oregon were increased by the Oregon legislature effective March 1, 2016. A new report by Christopher Monsere and Sirisha Kothuri, researchers in Portland State University's department of civil and environmental engineering, found a direct correlation between the increased speed limits and an increase in serious crashes. The Oregon Department of Transportation (ODOT) funded the study, which was the third in a series of reports conducted by Monsere examining issues in Oregon related to changes in posted speed limits.
A Summer of Bike-Ped Workshops: Registration Now Open

Last month we announced our week-long IBPI study tour of the Netherlands, and hot on the heels we've opened registration for our annual spread of three multi-day bike-ped workshops.

Transportation for the Next Generation: Summer Camps for Oregon High Schoolers

We're offering eighty full scholarships to four, week-long transportation summer camps in Oregon for high school students interested in urban planning, engineering, or transportation policy careers. Three of the camps are hosted at Portland State University, and one at Oregon Tech in Klamath Falls. Three of camps are only open to female / female-identified students. Women represent 50% of the workforce, but less than 15% in the transportation industry. We're committed to addressing this disparity by giving additional support to girls in STEM-related careers and the transportation workforce.
From the Blog: The E-Scooter Gender Gap
Blog by TREC director Jennifer Dill

Last summer, just as e-scooters were about to hit the streets of Portland, OR, I talked with a Wired reporter doing a story about e-scooters reaching a broader audience than bikeshare and other new mobility options – not just for "tech bros" was the headline. A survey of 10 cities had come out from Populus that showed more positive opinions of e-scooters among women compared to men. At the time, there was not any data out there. Fast forward to today and now we can do more than speculate. There is a gender gap in e-scooter riding, and it is not that much different from bicycling.
Friday Seminar: Words Matter: Recognizing and Addressing Modal Assumptions to Shift Transportation Culture
Friday, February 22, 2019 at Portland State University
Search #DriverNotCar or #CrashNotAccident on Twitter and you’ll find a vigorous discussion about the power of word choices to shape our understanding of what happens on the street and who’s responsible. When we directly examine and discuss the language we use, we acknowledge its power both to reflect existing attitudes and to shape developing attitudes. This presentation will uncover embedded biases or assumptions in common transportation terminology and provide tips and tools to help us broaden our inclusion as transportation professionals.
EFFECTS OF PEER-TO-PEER CARSHARING ON VEHICLE OWNERS’ TRAVEL BEHAVIOR: A paper published in Transportation Research Part C: Emerging Technologies by TREC researchers Jennifer Dill, Nathan McNeil and Steven Howland found that for some car owners, P2P car sharing was a catalyst to change their travel behavior.
