On: Microsimulation of Traffic Flow

Roundabouts with arms priority lead to deadlocks, I never thought about this.

Interesting to see this in practice and to just give the rule "ring has priority" for granted.

There's a big roundabout in my city that's in construction so some lanes are closed, when there's no traffic cops, people entering it cut you off, creating deadlocks, I've been stuck in that roundabout for >15min some times.

Aren't you describing the difference between roundabouts and traffic circles? Maybe this is US-specific terminology.

[Sohcahtoa82 → ghostly_s]

Roundabout and traffic circle are different terms for the same thing.

As described in the section you've linked to, they are not synonyms as far as how the USDOT uses them.
