Transportation systems researcher. The reason cities keep failing cyclists and pedestrians isn’t engineering. It’s deeper. It’s coalition politics and cultural signaling. That’s what I write about.

Vision Zero has had a mixed record in U.S. cities. Perhaps it's time to ask more fundamental questions about the purpose of our public spaces. The latest Infrastructure and Its Discontents essay is up: sethlajeunesse.substack.com/p/what-and-w...

Can we agree that satisfying legal definitions of “accessible” does not automatically render such places “usable?”

Milwaukee's mayor protecting "decades of established traffic patterns" from a boulevard that would free 16 acres and add $16M/year in tax revenue. Which patterns count as the unquestioned default, and which have to prove themselves? usa.streetsblog.org/2026/07/23/m...

Rebuilding the BQE costs 3x what removing it and building light rail would. Off-Ramp NYC ran the numbers. Street-level transit beats elevated highways every time: cheaper, pays for itself in tax and farebox revenue. We need to make highway removal a thing. www.nydailynews.com/2026/07/21/t...

The BQE’s broken math (and opportunity)For decades, the city Department of Transportation has asked, “How should we rebuild the crumbling triple cantilever of the Brooklyn-Queens Expressway (BQE)?”www.nydailynews.com

Surface parking has cratered 50% of Carrboro, NC’s downtown. Ergo, I walk 50% more steps than I would have if 0% of downtown was cratered by parking. Turns out surface parking is a public health win! 🏅

A freeway split Santa Monica's Pico Neighborhood 60 years ago. The city just funded a study asking: repair it, or undo it? Where else are we choosing the band-aid because removal feels too big to study? www.smdp.com/santa-monica...

Santa Monica Accepts $2M Federal Grant for I-10 Capping StudySanta Monica City Council unanimously approved a $2 million federal grant to study capping the Interstate 10 freeway with parks between 11th and 20th streets in the Pico Neighborhood.www.smdp.com

This is Greenville, SC’s Saturday farmers’ market. This is Downtown. This is Main Street. Nary a car passing through or edging into a parking spot in sight. This shouldn’t be exceptional.

Note the crossing signs on the side of this Main Street in Carrboro, NC. Also note the lack of a marked crosswalk. Question: when only ~20% of drivers yield to peds WITH a marked crosswalk at this location, what % are likely to yield WITHOUT a marked crosswalk?

BRT is often dismissed as the "cheap option." Guadalajara built one that serves 325K trips/day with universal accessibility across 46 stations. Maybe the consolation prize framing is the problem. itdp.org/2026/06/23/i...

In Conversation with Diego Monraz Villaseñor, Secretary of Transport for Jalisco, MexicoIn the metropolitan area of Guadalajara, located in Mexico’s State of Jalisco, the region’s newest bus rapid transit (BRT) corridor, Mi Macro Periférico, officially launched in 2022. It has become one...itdp.org

Worth remembering that a lot of people do not “prefer” to drive despite their driving behavior. No, these people drive because all alternatives have been made objectively unsafe, uncomfortable, impractical, or all three. Read: “revealed preference” is bs.

If we are serious about seeing more than 1-3% cycling mode share, we need to rally behind “minimum viable network density” policies. No more of these separated bike lane islands.

Not sure what those in power expect people, including those of us more and less able bodied, to do here, but…

A teenager can hear his classmates playing baseball from his stoop. The road between them has no crosswalk, no signal, trucks doing 40. He sometimes makes it across. When he does, someone tells him to get in left field. New essay ↓

The "right to the city" started as a radical demand. Now it shows up in displacement-inducing development proposals and community organizing campaigns against it. What happened to the concept and does it still impart critical force? www.tandfonline.com/doi/full/10....

Cities track every car parking space but often have no idea where cyclists can lock up. Las Vegas residents are fixing that themselves. This is both civic spirit and the city outsourcing its own planning failure. usa.streetsblog.org/2026/06/01/t...

International best practice (OECD/ITF) is to use three main indicators: Total road deaths (absolute scale of the problem) Deaths per 100,000 population (public health burden) Deaths per billion vehicle km travelled (risk per exposure). The USA is a notable outlier among developed nations.

California may gut its climate transit fund to hand free pollution permits to oil companies. Gas prices are the excuse. Transit riders, housing advocates, and the climate will no doubt pay the price. cal.streetsblog.org/2026/05/26/c...
