Any curb-cut, drive-thru or "sit in your car" style business should be heavily limited or outright not allowed in any area with many pedestrians (i.e. basically all of the city)

Streetcars should be equipped with a 3 body problem-esque nanowire to bisect parked cars exactly where they cross the right of way. I have fantasized about this for sidewalk/crosswalk parkers too, especially when I used crutches

Agree - I love the variability we get in holidays based on weather. Everyone in my neighborhood was out walking around as we strolled and it was lovely to see.

IIRC Ashland BRT failed because of pushback against getting rid of parking. So I guess don't bow to that pushback?
Also of course American infrastructure cost disease is a barrier to every transit project

I wonder what on earth is gonna happen to all these data centers under the pretty likely scenario that the glorious AI future companies are selling does not become 100% reality. And all the industries that are being buoyed by spending on them

Buses need to be faster it's so embarrassing. It's disrespectful of bus riders' time and decisions around stop spacing, fare payment and stop design are done with this implicit "you only ride the bus if it's your last resort" mindset which is so fucked

Personally i have done successful ferments with iodized salt so I suspect its "sterilizing properties" are a bit overstated.
Maybe a non-food use? Drying out water damaged flooring or something?

Interestingly express buses are least effective during rush hour. Still effective but the speed difference is biggest when there's less traffic

I'd be for 1 and/or 2. I think our standard spacing should be 1/4 mile, not 1/8 mile. I also think 1/2 mile spacing express buses save a lot of time for people with long stretches to travel

I did the data scraping and analysis for this graph and to be fair this is based on one week of data so the biggest peaks I would not show because they're based on fewer buses (since express buses are scheduled basically only during rush hour)

Express buses are definitely faster - the difference is smaller during rush hour but still >=10% for the most part, and outside of rush hour increases to as high as ~25%

Here's the map of average (express) speed by location overlaid on the route shapefiles - agrees with you assessment of 9 route, there are many things slowing it down in addition to stop spacing on the north half, but I'd say stop spacing still makes a difference there. Could break it down hourly too

I did the data scraping and analysis of express vs. standard - I basically hit the CTA bus tracker API for the express routes and their normal equivalents - during rush hour the difference is the smallest, maybe ~10%, outside of rush hour it can be much higher like 25%. That holds for 4, 9 and 49

Sharing this plot from somewhere - our bus stops are too close together!!

So my takeaway is that express spacing is free and effective, but we only deploy it when it makes the smallest difference and only on 3 routes. I'd love to see more routes running express and over a longer timespan.
Anyone have other ideas/questions about methodology?

So for example over the last 3 hours there have (obv) been no express buses, here are the average speeds:
I'm also thinking of looking at particular bottleneck locations once I have a couple days of data
