Re: [sumo-user] links priorities

[Jakob Erdmann <namdre.sumo@xxxxxxxxx>]

You need to set another junction type for this.

- in Europe, a common symmetrical type is "right_before_left" (which gets flipped for left-hand networks automatically)

- in the US, the typical type for this is "allway_stop"

See https://sumo.dlr.de/docs/Networks/PlainXML.html#node_types

Note, that neither type works too well in heavy congestion. Traffic engineers would consider putting in traffic lights for such intersections.

Thanks Jakob

How can I set equal priority for north-south and east-west axis? I mean, I have 120 edges with equal priorities (= -1), equal number of lanes and equal max speeds, I want my cars to have equal chance for passing the junction when its congested but as you say now when the junction is congested, all the cars in north-south axis have priority over cars in east-west axis.

The priority is resolved by number of lanes and speeds as well. All being equal, the nort-south axis gets priority over the east-west axis.

Priorities are simply sorted so negative values are lower than positive values and (-1 isn't special).

i have a question about the priorities of links. in an intersection, if 2 or more edges have same priority how sumo decides to allow cars first? and another question is about priority = -1 what does it mean?

thanks
