Today, the Trump administration repealed the endangerment finding: the ruling that served as the basis for limits on tailpipe emissions and power plant rules. Without it, we’ll be less safe, less healthy and less able to fight climate change—all so the fossil fuel industry can make even more money.

Such a thought-provoking piece to transit planning by renowned transit consultant Dr. Walker (PhD, Stanford, Humanities)!
I do think American transit planners tend to underestimate the value of proximity (and frequency), and prioritize the faster commutes to Downtown over more local destinations.

For Bay Area peeps about the potential consequences of failure of Connect Bay Area Transit Funding Measure
BART's newly released concepts for what they'll do if Connect Bay Area transit funding measure fails are terrifying.
Phase 1: 63% train hours cut & 10 station closures
Phase 2: Cumulative 70% train hours cut, 15 station closures
Phase 3 (if required): END BART SERVICE
We must pass the measure!

ICE detained multiple kids (all under the age of 10!) in the last week alone. Still kidnapping people based solely on the way they look. Still arresting parents at school pick up.
Nothing has changed in Minnesota. Nice words from the Admin won’t change that. ICE leaving will.

I’m thankful you weren’t around in 1870, 1880, 1890 when the NYC Subway was being contemplated on being built.
Because then you, your children, your friends, and millions of others would not be benefitting from a subway that was built over a century ago and still are benefitting to this day.

Folks, if you're into public transit, and you're not following Prof. Eric Goldwyn of NYU, then you're not doing Transit Sky right.

41 miles of new subway for the cost of free buses. Here’s an audacious, expansive plan to expand the subway’s reach & catalyze housing to attack the affordability crisis. An incredible effort from NYU Marron team. Excited for this to be out in the world:

I love Kathy Hochul! She is the best governor for transit in the country right now and in some time for New York State!
I love Gov. Hochul's level of transit expansion ambition! It's what we should be expecting in politicians.

So how did Hochul move to become, as one advocate sez, “the best governor for transit in more than a generation”?

Trump then pardoned the attackers.

The Cambridge side of the BU Bridge should be rebuilt with a bike/ped flyover to replace the Reid Overpass. Local topography means it doesn't introduce new climb. If we're going to build a bridge, let's prioritize people walking and biking (it would be cheaper, too).
