Re: [sumo-user] Meso Sumo

[Karl-Heinz Kastner <Karl-Heinz.Kastner@xxxxxxxxxxxxxxxx>]

Hello Sumo Team,

 

our net includes roundabouts. They are not marked as roundabout, only the priority in the middle is higher than the connected edges. If there are too much vehicles in the simulation, the roundabout will generate a deadlock. We add a Pic for this problem.

 

Would the simulation work better, if we use the roundabout tag or exists a function to protect about this deadlock?

<roundabout nodes="nodeID1 nodeID2 ..." edges="edgeID1 edgeID2 ..."/>

 

Best regards

Karl-Heinz Kastner

Hello,

By default there are no lanes in meso. By setting the option --meso-multi-queue, lane-specific queues are only created whenever an edge has multiple successor edges (this is meant to avoid left-turning vehicles impeding straight-going vehicles, for example).

At an on-ramp (1 successor) all vehicles are put into a single queue but this is not meant to represent lane usage (maximum throughput corresponds to the total number of lanes).

best regards,

Jakob

Hello Sumo Team,

we are testing the Sumo Meso Version 0.32. We generate a net with ramps and use it with a demand model. We detect a Bug on ramps for highways. All vehicles are on the right side, although the edge has 3 lanes. We add pics and the config file.

Can you help us with this problem?
