if you put bike lanes off arterials - they need to be prioritized at the intersection of arterials. the problem? this is exactly the issue US cities don't want to deal with. just put the bike lanes on arterials. it's where the stuff is people are going to. www.theurbanist.org/2019/06/07/b...

Bay Area transit friends: I have thoughts about how to fix Caltrain in Santa Clara County.

OK i read SB 79 amendments in full. It separates counties with 15+ rail stops. 15+ stops allows homes up to 6/7 stories within 0.5/ 0.25 miles of a station If under 15 rail stops, its only 4/5 stories 0.5/0.25 mi from a station. Cities can introduce their own plans if its equal in capacity to SB 79

@bart.gov the lights over the Downtown Berkeley atriums are burned out and too high to replace in routine maintenance. There's a 32ft scissor lift on the platform for the Station Fire Alarm project. Could Capital Projects loan Facilities Maintenance this lift to put in some LED T8 bulbs?

every analysis of transit safety should take a holistic, systemic approach to the issue. In this case, automation is 99.99% reliable and even rare errors are not dangerous. additionally, automation enables more service, increasing ridership and saving lives that would have been lost in car crashes

This is basically correct. Housing markets, transit networks and labor markets are all regional in nature, and so metropolitan regions are the appropriate administrative scale for making policy in these areas.

👀 It looks like there were banner drops all over the state this morning calling on @gavinnewsom.bsky.social to properly fund public transit. I am here for it. Newsom announced the May state budget revise drops tomorrow. That would be a good time make it clear he intends to, indeed, fund transit.

Another example - Caltrans is a big hurdle to housing development at Orinda BART, as Caltrans is requiring the land to be sold at fair market value. Both Orinda and BART have wanted to build housing on the massive parking lot. Newsom easily could have stepped up to solve this. From a 2023 report:

Raised crosswalks, when designed properly, don’t just slow motorist speeds, they give people on foot and bike a sense of belonging. Design shapes behavior. Signs just plead for it.

As far as I am aware, there is no provision for public transit in this highway widening project. Instead, this will double down on a road that faces flooding risk over the next several decades, inducing more traffic in the meantime, and providing no sustainable transportation solution.

Mid-rises rock and we should legalize more of them — but the idea that taller buildings are bad because they put you in the realm of birds and planes is poetic BS that doesn’t really mean anything. It’s like saying we shouldn’t build subways because “what are you, an underground mole person?”.

Like a lot of things this is downstream of weak state/strong corporate power. CA has struggled to force a ZE transition in the logistics sector, but it's easier to impose mandates on the public sector, so transit agencies are forced to test emerging tech for the heavy duty trucks, riders be damned.

A gutting of the public service is the path toward increased project costs & longer project timelines. I suspect that the short-term labor savings will translate into long-term capital costs.

Amtrak's management has a lot of problems, especially around cost-effective project design and delivery. But if the other frankly insane cuts that have been made over the last few months are any guide—and they almost certainly are—this will only make the problems worse.

Just asked a California transit manager if the state's Zero Emission Bus mandate is causing them to run less service than they otherwise would. He said: "Yes, definitely." A diesel bus only has to get 4 ppl out of cars to be better for the planet than an electric bus. Hmm.
