Yes, we don’t want AI generating fake research, & AI is being misused in terrible ways. But “AI” is a very broad term. What about grammar-checking tools? Machine learning models for data analysis? LLMs for qualitative analysis of large datasets? It’s a complex topic.

As someone who grew up in the 70s in San Diego, when bald eagles were threatened with extinction, I am still in awe every time I see one in my now home of Portland, OR. Today I spotted one on a cell phone tower above the car wash. Lousy cell phone photo seems fitting #birds

As traffic deaths among people walking and biking continue to rise—and as new mobility technologies rapidly reshape how we all move—Portland State University has been selected to lead a major national effort to improve roadway safety and accessibility. Learn more: trec.pdx.edu/news/new-roa...

Travel behavior researchers are always asked about transferability of findings, but we rarely get an opportunity to put it to the test. A fun piece of research with @smkothuri.bsky.social & @nwurban.bsky.social at @trecpdx.bsky.social is finally out! journals.sagepub.com/doi/10.1177/...

Um, no thank you.

"Storywork: The Prints of Marie Watt" is on exhibit through Dec 6 at PSU's Jordan Schnitzer Museum of Art. Stop by any Friday this month (except Thanksgiving) to see the free exhibit before or after our Friday Transportation Seminar in the same building. This Friday: trec.pdx.edu/events/psu-t...

Looks like I have a new route home today. The new protected bike lane on SW 4th is open, at least this part through Portland State Univ. Thank you @pbotinfo.bsky.social

Are you at #MpactPDX? Stop by the @trecpdx.bsky.social booth for some fun swag. Better yet, come by Tuesday at 1 pm for office hours with former congressman and Railvolutionary Earl Blumenauer.

The amazing Bev Scott revs up the #MpactPDX crowd Democracy is not for spectators. We need courage, not working under the radar. Don’t focus on ROI. Slavery had an ROI. Invest in people so that we can say “all the children are fine” We need to plan for opportunity, not just emergency

Rep. Earl Blumenauer at #MpactPDX sharing some Portlandia insights, calls on us to focus on what we can control, since “this administration will only do the right thing by accident.” @mpactmobility.bsky.social

Portland Metro Councilor Christine Lewis welcomes the crowd at #MpactPDX highlighting Metro’s focus on affordable TOD housing, and a tip about reservations at Kann @mpactmobility.bsky.social

Tens of millions of animals are injured or killed on Oregon’s roadways each year. This Friday, Rachel Wheat of ODFW shares opportunities to mitigate this, including the use of wildlife crossing structures, autonomous animal detection systems, and smarter project siting: trec.pdx.edu/events/psu-t...

This explains the trombone player in a banana suit I saw on the way to the bus tonight! Though, this is Portland, so it didn’t seem out of the ordinary.

I’ve received four fundraising texts in a few hours for this campaign. So annoying, though hard to know how many are really from the campaign.

What an unforgettable afternoon with #BensonBoone on the #BikeBus! The energy, the smiles, and the singing made it a ride we'll never forget.

Judge Karin Immergut’s ruling capped a dramatic weekend that included President Trump sending California National Guard members to Oregon and ordering others from Texas.

Judge Immergut in Oregon v Trump now: "I grant plaintiffs second motion for a TRO." Federalized Texas and California Guard to Portland is a "DIRECT CONTRAVENTION" of court's TRO from Saturday. Both on 12406 statute and Tenth Amendment grounds.

HAPPENING NOW: Judge Karin Immergut hears emergency arguments as California and Oregon seek to block President Trump's deployment of federalized California National Guard troops to Portland. 🧵

Apparently inspired by yesterday's embarrassing loss in court, Trump has ordered California Gov. Gavin Newsom to send 300 of that state's National Guard members to Portland. Oregon Gov. Kotek says 100 have already arrived, while at the ICE facility, federal agents are growing more violent.

“I always thought people must be provoking them or something, that they would never do this unprovoked. Obviously, I was wrong.” 84-yo woman knocked over by federal agents, resulting in concussion. “People have to know that we are not Antifa…We’re just regular Portlanders who love our city”

Dear NPR. No. Just no. This is not how you help. One of the several thousand actual road safety experts here. We are easy to find. Maybe give one of us a call next time, ok?

We will see you this Sunday at #SundayParkways downtown! (Look for the TREC cargo trike, stop by and say hello!)

Are you doing interesting work in transportation? Share it in a poster or lighting talk at the PacTrans conference in October. Practitioners, consultants, researchers, public/private/nonprofit - everyone is welcome to present! The deadline is August 27: pactransconference.com/call-for-pos...

Speaking of street transformations, the new restrictions motor vehicles on Pike Place outside the market made me enjoy the place far more then my visit in 2008. The pilot project was a window of opportunity (street repair work), a common origin for street transformations.(repost with gif)

I love wandering around cities. In Seattle today I randomly walked down Terry Ave., about 1/2 mile NE of Pike Place. It was a little oasis. Of course I had to find out what it was before, and Google Streetview answered.

Safe mobility Infrastructure is critical in tribal communities, which experience a disproportionately higher rate of pedestrian fatalities. Learn more about the Pueblo of Jemez quick build and community engagement by joining our Aug. 28 webinar ➡️ buff.ly/B1KxZZK

Research from Tim Althoff and coauthors links moving to more walkable cities to more walking, and vice versa. This type of "natural experiment" research is rare and very valuable.

Are you working on something interesting you want to share with other transportation professionals and researchers? Submit an abstract for a poster or lightning talk at the PacTrans Conference in Portland, OR, October 10, 2025. Abstract Deadline: August 20. @trecpdx.bsky.social

We had a great time last week at the @trecpdx.bsky.social transportation camp. OPB’s Tiffany Camhi captured it well.

I’m spending this week with 24 Oregon high school students, leading a transportation camp. It’s what all older transportation geeks (like me) wish they could have done in high school. Today @trimet.org gave us a tour of the Robertson Tunnel! @trecpdx.bsky.social
