-> sounds like a bug in the car following model. This was an issue with Wiedemann.

Hello again,

I have now tried the same simulation with the standard kraus-sumo
algorithm and this problem doesn't occur so often, but it does neither
the less.
The reason is that the vehicle are on their destination edge but are
stopping before they are arriving the destination position. So after the
time-to-teleport ends they are teleported.

Is this a bug in Sumo?

With best regards
Claudius Heine

Hello SUMO users,

I am using IDM to simulate the traffic in Augsburg, Germany and got a
strange problem while simulating with SUMO.
The vehicles, that arrives on their destination edge, stops and waits
for some time. This behaviour creates lots of traffic jams all over the
map.

Is there any parameter or something to change this behaviour?

With thanks and best regards

Claudius Heine

I could not confirm this for the default carFollowing Model. It appears to be specific to IDM. Futhermore it is highly dependent on the IDM parameters.

  • @namdre changed milestone from "0.15.0" to "1.0.0"
  • @namdre changed priority from "critical" to "minor"
