Visualizing low-traffic neighborhoods and gated communities #660

Closed dabreegster closed 2 years ago

dabreegster commented 3 years ago

Today, there are two types of roads colored pink.

Screenshot from 2021-05-21 14-06-49 This is a gated/private community in Seattle called Broadmoor. There's a physical gate surrounding this neighborhood; you have to show an ID to a guard to walk or drive in.

Screenshot from 2021-05-21 14-08-40 This is a Stay Healthy Street in Seattle. Also called "play street", "living street", "low traffic neighborhood" in different parts of the world. People can drive through there only if they live on that street, or they're making deliveries. Pedestrians and bicycles and people playing outside are supposed to be the main use. They usually have some kind of sign or barrier at the entrances: 960x0

We should probably depict these differently. The pink color isn't meaningful at all. We have the unzoomed view, shown above, and also the zoomed-in detail view like this: Screenshot from 2021-05-21 14-11-20

Maybe we could have a simple 2D top-down rendering of a barrier or a gatehouse? For the unzoomed view, I'm not sure what to do.

I started #770 for more general discussion. I'm enjoying the conversation and learning lots, but yeah, let's stay focused in this issue on rendering/viz please

@trangeriale, I think the color scheme you've chosen for the different LTN-related elements works really well on this image. We currently use a different scheme for the unzoomed view. Do you think we should switch to something closer to this example for the LTN tool? It should be hopefully be simple to try it in https://github.com/a-b-street/abstreet/blob/master/map_gui/src/colors.rs... figuring out how all of this works in the zoomed-in view is another matter, though. I like Robin's transparent green tarmac layer idea for that.

Lots of awesome discussion here, but nothing actionable anymore. #856 has some ideas for improving what we've got further
