LA deliberately cut its housing capacity from ~10M to ~4M homes through single-family zoning. It hit that cap in the 1990s, then added 5x more jobs than homes 2010–2015. The result is one of the world's least affordable cities.

Real estate survey: "77% of Americans would pay more to live in walkable neighborhoods." Reply guys: "That can't be true because I wouldn't pay more."

I do not think it is fair to compare me to Adolf Eichmann because I work on making it easier to build ADUs and starter homes.

No, your identity is being the kind of person who will take money to lobby for Silicon Valley Eugenicists and corporate landlords, and have such a deficiency of conscience that you're self-satisfied and smug about it. A contemporary version of Hannah Arendt's Adolf Eichmann.

Vivir en barrios caminables se asocia con menor mortalidad, y el mayor efecto protector se observa en los grupos con menor nivel socioeconómico. Estudio con dos millones de personas a lo largo de 15 años.

Pasadena should permanently close this section of Green Street to cars and reclaim it as a community plaza.

The UK government plans to invest £4.5bn in active travel over five years, creating 5,000 new routes and 10,000 safer crossings. The strategy aims for 55% of short urban journeys to be walked, wheeled or cycled by 2035. gov.uk/government/news/cycli…

Elon literally builds the least efficient “transit”in the world. Even if I’m not hating I can give him the first 15 years of Tesla and all of SpaceX. His hyperloops are the dumbest, most useless boondoggles ever
If he’d hired Elon to build his high-speed rail project, it would have been finished by now, instead of moldering, unbuilt, as a symbol of government incompetence and waste

San Francisco NIMBY socialists are converting to straight up blood-and-soil fascists before our eyes. "San Francisco land for San Franciscans (and we get to define who is a 'San Franciscan')"

Public agencies, consultants, advocacy groups, teachers... they'd all benefit from having a digital library with explainer videos like this one. Any and every transportation topic.

I don't do a lot of posting here but today, I thought a story needed telling and some dots needed joining. It's about the most powerful health, cost-of-living and growth policy you've never heard of: linkedin.com/pulse/most-powe…

Building California's 1.8M needed homes in walkable, low-VMT neighborhoods could cut statewide driving 4.5% and avoid 8 million tons of climate pollution annually by 2033. Housing location is climate policy. cayimby.org/blog/did-someone…

Stockholm’s pedestrian fatality rate per 100k is 0.45. The U.S. is over 5x that. Like much of the EU Stockholm uses standards of 9.8’ for city street lanes, even narrower for residential ones, and allows for 10.8’ in bus and truck corridors. The U.S. sets 26’ as a minimum width for a two lane street and common lane widths on city streets are 12-14’. Yet when proposals are made to narrrow lane widths along dangerous streets, local fire departments are first in line to stop them.
Lots of cars in Stockholm. Lots of bicycles. Lots of pedestrians. Seems fine?

Parking reform is one of the most effective ways cities can reduce #traffic, improve safety, and make better use of public space. The NYT highlights options like more metered parking, residential permits, dynamic pricing, and better enforcement. The broader point is that curb space is valuable, and managing it better can make streets safer, calmer, and more enjoyable while generating revenue that can be reinvested in #publictransportation and other improvements that benefit everyone.

An awful lot of people insist both of these are true: 🚌 Distributing wealth to pay for transit infrastructure is communism. 🚗 Distributing wealth to pay for car infrastructure is capitalism.
