So yeah that comes at the trade-off of the screen's 'accuracy' and 'live-ness' being dictated by how much margin do you want given your solar and battery kit
We've throttled down the refresh to every 30 seconds, which is good enough most of the time
Ultimately, solar isn't magic; e-ink isn't ideal

Yes, it's considerably less — that's the point of e-ink b/c solar simply doesn't have the same output as a utility connection. Our 50W solar/140Ah battery package gives us ~2 weeks of life w/o sun
Lower power draw also means the screens are considerably less dynamic and arguably less conspicuous

It's just like a TV at home except this needs to achieve 2-3k lumen brightness to be visible in direct sunlight
Our 55" LCD screens are spec'd at 350W max
You're talking about needing 7.7KWh/day to run it 22hrs if you shut it off for the 2 hours when there's no service. Solar is impractical

I can see that coming southbound from the block one-way blocks north!

Yeah I imagine we have similar constraints in Boston and that cost will vary based on how far the closest utility connection is
I've never worked very closely on a shelter project before; only told second-hand that most new shelters were made solar. Advertising vendors will pay a lot for line power

Exactly, which ironically is really done well two blocks south! This is also a very decently protected intersection and bike infrastructure (pics from one block south)
The fact that right turn and bike light can show green at the same time is also problematic...

Even then, it's not like this street has many obstructions or is high speed. Whenever I've walked here, cars are fairly slow. Driver would've had time coming up to the intersection to pass a person in the bike lane or coming from the opposing direction
This was pure IDGAF negligence on the turn

Yeah that's just the rough all-in number for the sidewalk work and utility connection. I could check with other colleagues what that cost breakdown is. Part of me thinks that a not insignificant portion of that is labor and permitting
Usually it's also in the context of building a new shelter

Oh yeah I absolutely have no sense for cost structure and I'm dubious English language LLMs could help me find those numbers in Korean
The magnitude of work is still the same, though may be made easier if they manage utility conduits differently in Korean cities

Oh that's nice. A pretty typical stacked 13" dual display like the ones we deploy
There are like 4 or 5 vendors who produce units like this
This is easy to power with solar and this is what NYCDOT is trying to deploy at scale because it doesn't require utility work and owned by them

Where? Utility work? Or the display enclosure?

I vaguely remember seeing this and think my NYCDOT colleague talked about it. The shelters were built for provision of LED boards but I don't remember why JCD has only installed a few
I can ask. I suspect the issue is somewhere between city staff capacity and the JCD contract

*run power to many stops
The street furniture program with JCDecaux that added the shelters is over two decades old (adding another 100 with the 2023 contract extension) and these screens could probably be easily retrofitted to the shelter structure

Actually this reminds me I need to follow up on an email from my NYCDOT colleague managing this program. We're all on an email chain following CTA's e-ink pilot similar to the one he's running for NYC
Right now, that utility cost to crack the sidewalk and run power to shelters is the biggest hurdle

The design is hurting my eyes a bit but you can always do that better
Hardware looks like a 46" LCD display which runs about $6-10k depending on the vendor and support/warranty
The bigger cost is getting utility power to the shelter (~$20k/stop). Curious if this was a specific capital program

First screen also looks very typical of Korea in a way that does not translate well to the US: effectively a commercial screen inside an enclosed bus shelter which reduces cost
The screens we deploy cost probably 2x or 3x this to be built as street furniture with impact resistant glass/enclosure

That second screen looks really nice! Was it e-ink or some other display tech?
Third screen is nice and it works out that Korean is an ideographic language that squares off pretty well for an LED screen
Fourth screen has the same maintainability problems as NYC's custom legacy realtime screens

Even at public meetings it felt like I was embodying those strawmen for them
As a YIMBY, I was fighting my young left liberal neighbors in ways that made it sound like I was glorifying capitalism and gentrification as a method of displacing black and brown neighbors
