Credible speed camera program: 1. Focuses on ticketing the truly deviant - if large % of drivers are speeding, that's a design problem. 2. Is paired with an ethic of iterative engineering to reduce violations & improve safety. 3. Uses revenue near source for safety changes.

I've not lambasted things for not being perfect. I reject the simplistic reaction of many who, in their war on cars, want to have a war on drivers of cars. If this is about human prosperity, we're losing the plot thread.

Thank you, federal infrastructure bill. I'm sure one of the cities in this corridor can get a few million in a reconnecting communities grant someday.

Missouri's operating budget now includes a $2.8 billion plan to widen Interstate 70, instead of the originally proposed $860 million. Here's what else the proposed budget does and doesn't include: news.stlpublicradio.org/government-pol

A city that allows bulk storage to be built on a lot where public utilities (sewer/water) are available is being led by unserious people. If bond rating agencies were serious people (they are not), such a scenario would result in an automatic downgrade.
Quote Tweet
Any town in South Jersey that allows storage to be built in rare sewer connected roads is doing it wrong IMO. Anyone disagree? It’s almost impossible to build missing middle MF housing in non-sewered areas…

Local leaders need to create street design teams. Appoint a non technical person to run it. Make the engineers work for them, not be the person in charge (whose values and priorities dominate). You'll get their expertise where it's helpful, opposing views where it's not.

This is why we have to redirect traffic engineers, not expect them to evolve a new understanding on their own. They are overly sensitive to auto mobility by experience. Asking them to correct that is asking them to go against decades of experience.

Engineer opposed to bollards along the sidewalks because automobiles might get damaged. The only surprise is that this honestly and widely held belief among professional engineers was spoken publicly. It's usually just subtext.

Local reporting is tough. This reporter went the extra mile to not only grasp the message but convey it in a compelling way. Great summation of concepts.

I'm so looking forward to this! I've spoken many times on Original Green things across the country and abroad, but it's almost always a presentation with a bit of Q&A. This one will be an actual conversation with colleagues. Please join us! classicist.org/calendar/event

Give me a credible strategy for ridding the transportation system of the so-called "reckless". Won't we always have the "reckless" so long as we have humans? And, if so, don't we need to take that into account as we design streets?

Having us all pointing fingers at each other is a feature of transportation safety policy, not a flaw. Identify your adversary, blame them, and don't look behind the curtain (it's too hard to change the system anyway). We don't need to be so feeble.

Something I’m thinking about today: is it possible to effectively advocate for pedestrian and cyclist safety in a loving way? It doesn’t feel like it. twitter.com/kelseyhuse30/s…

Wrong again! Any city can start making their streets safer now -- to HUGE effect -- and they can do it on a shoestring budget. Start with launching your own Crash Analysis Studio and refocus your city's public works energy on what you can do right now. actionlab.strongtowns.org/hc/en-us/categ

Replying to @actfortransit and @Cruise
Respectfully disagree with NTSB on this one. We can try to design roads and cities to be safer, but this will take decades, which is an insufficient solution to the problem we face today. In a world without AVs, I’d take that incremental gain, but we can do better now.

This IS awful. Believe the myth of human error --> America of speed cameras and automated vehicles Recognize the role of design --> America of stronger, more prosperous cities PS - It costs less and builds more local wealth when we fix our streets.

This is awful. “Nearly 43,000 people died in U.S. traffic crashes in 2021, the highest number in 16 years” Almost all due to human error. This is what motivates us to work with urgency at @cruise. abcnews.go.com/US/wireStory/d

This street won multiple Complete Streets awards. It's a horrible & deadly stroad that separates a residential neighborhood from a DC Metro transit stop. Check out these before and after photos (I double checked -- we don't have this backward).

Just put up a speed camera -- a proven technology -- and this will be safer. After all, all drivers need to do to avoid a ticket is drive the speed limit LIKE A DECENT HUMAN! (All you speed camera advocates, is this what you truly believe? It seems like it. I find it absurd.)

When you don't understand that design influences behavior, you think a new sign will make the racetrack safer.

Great thread on our most recent Crash Analysis Studio. We make these sessions available to everyone with the hope that others will copy this approach. These crashes are tragedies. We owe it to society to learn the hard lessons. Don't be afraid of this kind of self-reflection.

Last week @StrongTowns held the 3rd Crash Analysis Studio for a crash that tragically killed VCU student Mahrokh Khan. Based on that analysis and comments I have taken a bit to illustrate the problems and propose how this intersection could be fixed. Thread: 🧵

I thought this was an April Fool's joke, but no. Try to find a Catholicism-based argument here. Even one. There is none. So, more accurate headline: Catholic makes the Libertarian case for cars.

I'll speak through my own (Catholic) faith for a moment: The very human reaction to want to punish those we are angry with, to see them get theirs, is a path that leads to many dark things. We need to struggle against this reaction, especially in local public policy debates.

Without these things, speed cameras are performative, predatory, and not going to result in any added safety, in most instances. However, they do seem to tickle the sanctimonious bone of those engaged in a war on car-drivers. Also unhelpful.

And this thinking suggests that, if you listen to the radio, or read a sign other than a traffic sign, or even talk to a passenger, you're being reckless because you're not "single-mindedly focused on driving." That's fanatically absurd. And unhelpful.

We can pretend this is true. Heck, we can even pretend this is humanly possible (it's not). Or, we can recognize that we must design streets for the humans we have, not the ones we wish we had. Engineer for slow speeds and you'll get slow speeds. Everything else is posturing.
