Re: [sumo-user] Teleporting

Hello,

The issue you describe is a common occurence with OSM-derived networks.

What netconvert options did you use?

There are a number of options that may be set to improve the OSM data heuristically.

Take a look at

http://sumo.dlr.de/wiki/Networks/Import/OpenStreetMap#Recommended_NETCONVERT_Options

http://sumo.dlr.de/wiki/Simulation/Traffic_Lights#Improving_Generated_programs_with_knowledge_about_traffic_demand

A core issue with OSM networks are complex intersections. A number of improvements have gone into the latest development version of netconvert in regard to importing these intersections.

You can already try it out at http://sumo.dlr.de/wiki/Downloads#SUMO_-_Latest_Development_Version

regards,

Jakob

Hello,

I’m currently generating a SUMO scenario using a well-known city in the UK. I used OSM to obtain the .osm file and used netconvert to convert it to a .net.xml file. However, I am getting quite a few teleportations and I’m worried this may skew the results. The 2 main warnings I’m getting are 'Warning: Teleporting vehicle '44'; waited too long (yield)’ and 'Warning: Teleporting vehicle '1851'; waited too long (jam)’.

>From my research, I’ve come across the option 'time-to-teleport value="-1”’, however, I have found that this causes indefinite deadlocks where no vehicles are able to move (even with a seemingly visible clear path in some instances). I believe that this may be caused by the netconvert process, leaving in some intersections which don’t allow clear passage, I am also unsure about traffic lights - are there any options to improve these? Are there are further options to netconvert which would allow less collisions/vehicle jams & yielding?

Kind regards,
Jonathan
