The Trump admin is causing chaos in transport research. Studies have been canceled, datasets have vanished, and experts have been fired. The Nat'l Academies’ Transportation Research Board has caved to Trump’s demands for censorship, triggering upheaval. Its future is in doubt. From me (w/scoops) 🧵

“So why would I go through the pretense of peer review if the process is ultimately outsourced to an algorithm? I do not care for the aesthetics of peer review. We are not children playing academics. We are supposed to be doing substantive, not performative work.”

I'm deeply saddened to share that Donald Shoup passed away last night. He was the ideal academic—curious, methodical, and concerned with turning ideas into real-world change. TAing his parking course these past few years has one of the greatest honors of my life. Rest in peace, Shoup Dogg.

Study explores women’s ‘personal safety burden’ in using public transport. Describes the five dimensions this take: cognitive, temporal, emotional, financial and social. Shocking (if sadly unsurprising) reading. What helps? Well-lit environments and the presence of staff. CCTV not overly effective

🚨 I have a new paper in @pnas.org! Big cities provide huge opportunities for workers to climb up the income ladder through their large number and diversity of jobs. Big cities also have higher racial wage inequality, which is getting worse over time. #geosky #econsky www.pnas.org/doi/10.1073/... 1/

I think it’s important to understand that they aren’t going to crater the economy as part of some 11-dimensional chess move. They are going to crater the economy because they are very, very stupid, and cannot handle being told “no.”

How would it look if we started afresh with allocating street space? "Car users, on average, had 3.5 times more space available than non-car users. While some allocation mechanisms are more plausible than others, none is without disputed normative implications" www.tandfonline.com/doi/abs/10.1...

Traffic evaporation is the opposite of induced traffic demand. “Initially, everyone thought it would cause gridlock. But people adapted. Now we can’t imagine the highway ever being here.”

The year is 2035. I meet President AOC in the Oval Office. "You've done well," she says. "By telling men to dress gay, you've lowered the population rate by 90%, thereby reducing carbon emissions." She slides me a manilla envelope. I can now afford a home in a walkable neighborhood
