Some advice from SF: 1) Don't let perfect be enemy of good 2) Start with quick-build 3) Focus on all aspects of delay and reliability, esp congestion, signal and dwell delay, plus headway management 4) Make continuous progress Links: www.sfmta.com/projects/mun... www.sfmta.com/reports/fast...

What if I need to pass a dangerous driver on my ebike to get out of danger? Or get to the hospital? If these sound ridiculous, it’s because people have normalized those excuses for cars. Speed limits for both.

The high-speed rail authority can't force PG&E to move it's stuff out of the way of the people's rail project.... But the governor and state lawmakers do have that power. They can pass laws and regulations that make PG&E play nice. The lack of movement is on the politicians, not the engineers

California’s high-speed rail authority made a legislative wishlist. It mostly stalled out
California’s bullet train agency said timely construction of the rail line depended on these reforms. They mostly failed.

This circulation-focused design provides stronger bus priority than signal timing tweaks, without requiring a $100M street reconstruction or extra-wide right of way.

Infrastructure Weak @infrastructureweak.bsky.social · 24/09/2026
The Tremont Ave design allows cars to turn left or right to enter the one-mile busway extent, but they must turn right to exit at the first opportunity. This provides full car access to the street, while shifting through traffic away to speed up buses.
Same image from above.

"Busway Turn Map" of Tremont Ave in the Bronx. The busway extent is a one-mile stretch of Tremont, across ~11 one-way cross streets. Cars are permitted to enter Tremont by turning right or left from the one-way cross streets approaching it, or to cross Tremont on the same streets. However, they must turn right to exit Tremont at the first opportunity along it.

Circulation planning is what we need to do to make pedestrian crossings shorter and safer, add room for bikes, and speed up buses while accommodating car access. It works where you don't have an 60ft-wide street to put all of these things.

We should reform our current planning paradigm to do a better job of surfacing projects like this that improve service with targeted investment, and our project delivery systems to require fewer grant applications and consultant bid cycles, so that improvements can be made in a timely manner.

Other solutions could be new rolling stock with faster acceleration, or skip-stop service at a couple of strategic stations. But those have obvious cost and service quality drawbacks, respectively.

North Bay Transit Riders (especially @dereksagehorn.bsky.social) have been pushing SMART to prioritize a siding extension project that would enable 30-minute service, unlocking good transfers to buses up and down the line. SMART is studying it with Caltrans, but there's no commitment to build.

Infrastructure Weak @infrastructureweak.bsky.social · 24/09/2026
You can see here (in my insane chicken scratch) that this mismatch between SMART's 32-minute and GGT's 30-minute headways causes the transfer time at San Rafael to grow by two minutes every cycle. They do their best to mitigate it, but some of the transfer windows are very bad.
Photo of a sticky note with messy pen writing laying out a table of the waiting time for transfers between SMART and the Golden Gate Transit 101, as of April this year. 

In the southbound direction, SMART trains 1, 3, 5, 7, and 9 have transfer wait times of 7, 8, 6, 19, and 17 minutes. Trains 11, 13, 15, 17, and 19 have wait times of 15, 13, 11, 7, and 33 minutes (that last one has a window of 3 minutes, but that's not enough time for everyone to make it). Trains 21, 23, 25, 27, and 29 have wait times of 29, 25, 6, 19, and 17 minutes.

Northbound, there is no 101 bus transfer for Train 2. Trains 4, 6, 8, and 10 have wait times of 14, 16, 18, and 5 minutes. Trains 12, 14, 16, 18, and 20 have wait times of 7, 9, 11, 5, and 9 minutes. Trains 22, 24, 26, 28, and 39 have wait times of 13, 17, 16, 18, and 20 minutes. Continuation of the previous table, on a second sticky note. 

Southbound, trains 31, 33, 35, 37, and 39 have wait times of 15, 13, 11, 9, and 7 minutes. Trains 41, 43, 45, and 47 have wait times of 33 (3), 29, and 25 minutes. 

Northbound, trains 32, 34, 36, 38, and 40 have wait times of 7, 9, 11, 13, and 15 minutes. Trains 42, 44, 46, and 48 have wait times of 32 (0), 9, 13, and 15 minutes.

Yep. MASCOTS has been a great service improvement, but it would ideally have generated a list of capital projects to go even further. SMART is currently limited to a 32-minute headway by single-track segments (after the originally-planned 30-minute schedule did not pan out).

The bougiefication of Rockridge, Oakland, fueled by single family zoning. These are the same three homes in 2019 and today. With different zoning, capital would go toward converting these 100-year old homes into multi-family housing, a 2-block walk from BART. Instead, people are just upgrading.

A satellite view makes the advantage of the Vine Street site clear. This isn't a 5- vs 7-minute walk as the Mayor claims; it's a 10-minute walk vs basically no walk.
Satellite view of Healdsburg, with two SMART station location alternatives marked in red. The one on the right, at the historic depot on Hudson, is flanked by a self-storage facility, train right of way, and single-family homes, without much parking. It is a ten minute walk to Healdsburg Plaza in the center of downtown. The one on the left, at the Vine Street parking lot, is two blocks from Healdsburg Plaza, within the more urban part of the city.Excerpt from the article. 

Healdsburg Mayor Chris Herrod said that although preferences for the depot site had a tinge of nostalgia, it was also rooted in the belief that downtown Healdsburg is broader than the area immediately around the plaza. Pedestrians leaving a Hudson Street station could pass ample tasting rooms, restaurants, antique shops, music venues while walking toward the city’s core, he said. 

“To have them come up now and ask to rethink at this fairly late time in the game is flabbergasting,” Herrod said. “I’m going to be open minded, but honestly I doubt there’s anything there that’s going to shift us.”

Herrod said he once timed the walk to the plaza from both potential station sites and the difference was minimal: five minutes from the Vine Street site and seven minutes from the Hudson Street location. 

The city council last reaffirmed Hudson Street as its preferred site in 2024. A city report produced that year estimated that a downtown station could require reducing parking spaces in a nearby lot from about 350 to 300 and could potentially require removing trees and realigning a portion of a trail.

To the candidates who said they support bus lanes but not a bikeway on San Pablo, note that right side bus lanes w/o dedicated bike infrastructure are legally bikeable, so people WILL bike there if no other facility is provided.
