Hey wow Seoul Station has a giant LED screen in the main hall just like Moynihan Train Hall but also uses part of it for a fantastic animated train status and information display.
Imagine that.

Great news! Connecticut governor Ned Lamont, a noted coward, has finally located his big-boy pants and signed the legislature's amazing, ambitious housing bill. Among other things, it nukes parking mandates!

While NY is considering mandating two-person trains, the DC Metro not only already operates with one person, but recently reactivated its automatic train operation system.
Now, continuing to follow best practices, Metro has announced plans to move towards driverless trains.

The major impact:
On average, tracts on the North Side or downtown that were downzoned between 1970 and 1990 gained only 65 units between 1990 and 2010, while non-downzoned tracts gained 470 units on average, seven times as much.
This had cascading impacts on home prices and demographics.

What happens when you downzone?
Our new open-access research paper in @findingspress.org investigates effects of decades of downzoning in Chicago.
Findings:
—Downzoned areas added 1/7th of the new units as comparable non-downzoned areas;
—Downzoned areas became more white & were more expensive.

New from me (with @talimendelberg.bsky.social): are concerns about 'neighborhood context' real? (spoiler: yes, very much) Do people prefer traditional/brick buildings? (spoiler: no). And does changing style to "fit" boost support? (spoiler: only a tiny bit). doi.org/10.1177/1078....

NEWS! Looking likely that the housing related ballot measures will pass with over 1.5 million votes counted.
Prop 1 (upstate ski resort) and Prop 6 (moving election years) might be in peril
But people love digitizing the city map! (Prop 5)

Aaand that’s exactly what happened! Disappointing that he’s no on 6, I feel like that one might actually end up being the most impactful if passed. Why would government work at all in a democracy if people don’t vote?

Pre-registering my NYC election prediction (yes I think affective partisan polarization will prevail in Sliwa’s favor):
Mamdani: 52%
Sliwa: 21%

Anecdotally seeing a lot of Mamdani supporters pushing No on Ballot 6 (move elections to on-cycle), which is interesting because historically it seems like the NYC local election crowd is much more conservative than the typical general election voter
