Re: [sumo-user] Realistic Simulation with traffic data and calibration

[Jakob Erdmann <namdre.sumo@xxxxxxxxx>]

Hello,

1) due to some unusual geometry (possibly related to the footpath), the connection is incorrectly classified as a partly-left turn rather than a turn-around and so get created despite the no-turnaround options. You could try importing with option '--keep-edges.by-vclass passenger' to get rid of the footpath.

2) Yes. It's common for the lane numbers in OSM to be incomplete. See 'remark for data consumers' at https://wiki.openstreetmap.org/wiki/Key:lanes#Description

Obviously, this can be a major source of jamming in the simulation.

regards,

Jakob

Thank you, I will try this.

Furthermore I got data for the traffic lights to set the tls programs more
accurate. I used tls_csv2SUMO.py and got warnings like that:
"Warning: No link definition for connection (24654535#0_1, -24678549#1_1)!.
Using 'g' by default."
But this connection really shouldn't have any traffic on it. This would be a
turnaround on an intersection. I already used --no-turnarounds and
--no-turnarounds.tls.

I also noticed that there was one lane missing in the network. The road has
3 lanes in google maps. But somehow openstreetmap exported only 2 lanes. Is
that a common bug?
