The more linear, the worse the traffic flow.

[–] Glowstick@lemmy.world 16 points 2 months ago (1 children)

Is that your guess, or is there a specific source that says that?

Its not entirely clear, but it can be seen that traffic is worse when you have 20 traffic lights for crossroads in a row... Or at least its logical. The cities that grew over time with circular planing have better capacity even on thinner roads, meanwhile grid cities have up to 8 lane roads (4 in 4 out) very often as their main road.

Its not 100% clear but its pretty likely that its one of the factors. Another one is public transport.

Charlotte laughs at that.

Probably wouldn’t be so bad if they actually built the fucking light rail.

[–] woodytrombone@lemmy.world 2 points 2 months ago

you take your half-built light rail that exists to ferry people into Tepper's stadium and you'll like it!

Who?

She's stuck in irregularly shaped traffic.

[–] Cube6392@beehaw.org 3 points 2 months ago (1 children)

The city that's the least linear. Charlotte is a constant log jam because for major metropolis cities you do actually want a directional grid specifically for making the city easy to navigate with multiple outlets for traffic to flow in the event of a conflict (break down, accident, road work, etc). A city that doesn't prioritize navigability will be filled with culs-de-sac which are horrible for traffic and navigability

[–] YourPrivatHater@ani.social 1 points 2 months ago

Navigation doesn't mean you have to have a gridiron Pattern... As said, its the opposite.

@YourPrivatHater try explain that to the good peeps of Sao Paulo ... Rome, etc. ... @Blaze

[–] lvxferre@mander.xyz 4 points 2 months ago* (last edited 2 months ago) (1 children)

São Paulo city is a messy case. It started out roughly circular, then that circle was distorted into a grid plan, then that grid plan was tied to a bunch of mismatching grids. Picture related:

As such it's hard to reach any conclusion taking its general layout into account.

@lvxferre many of these cities shown here have external constraints (rivers, harbours, mountains, valleys, etc.).
