Re: [sumo-user] Vehicles stopping instead of going through intersections

[Jakob Erdmann <namdre.sumo@xxxxxxxxx>]

The define connection layout does not conform to the simulation standard: As a general rule, connections from the same edge should not target the same lane. (Netedit makes you hold down a special key to make you aware of this).

In the case of cars coming from the morth, most likely they have determined to use the connection to the second-from-right westbound lane (which is full) for strategic reason further down their route (it's hard to tell without running the scenario). That connection should not be available from the right lane of the northern inbound road.

Jakob

In many of my simulations it seems that gridlock is worse than it needs to be (and probably worse than in real life) because often vehicles stop at an intersection and wait much longer than necessary even though there is an empty outgoing lane available to them. For example, in the attached picture, cars coming from the top are waiting an excessively long time to turn to their right (our left) even though there are outgoing lanes open to them. 

The intersections are of type priority, and all the roads are the equal priority. 

I hope the allowed turns and the cars' turning signals are sufficiently visible.

Thanks in advance for any help.
