[sumo-user] Person is jammed on empty edge and colliding with themselves

["Albiston, Gregory 2012 (PGR)" <gregory.albiston2012@xxxxxxxxxxxx>]

Hello,

I have a scenario which involves a lot of pedestrians moving about on defined sidewalks. The plans have a number of stops which the persons wait at for prolonged periods. When executed for a small number of people there are no problems. However, in the larger example (see attached) there are warnings of "Person #### is jammed on edge".

In the attached scenario, an early example of this is "Resident1773" at time 28418 on edge "-121". When viewed in SUMO GUI, the person can be seen to walk along the edge and arrive at/near the arrival position, stop and then continuously switch from sub-lane to sub-lane on the sidewalk. The exact arrival position is occupied by one or more persons.

I've tried using the attribute "parking=true" from http://sumo.dlr.de/wiki/Specification#Stops but this didn't seem to work and isn't actually used according to http://sumo.dlr.de/wiki/Specification/Persons#Stops. I've also tried setting the person to teleport (which wouldn't be ideal) but this doesn't work either. Finally, I tried a small scenario with two people arriving at the same stop but one being first in, last out to see if they block the other but this didn't occur.

There are also several warnings of persons colliding with themselves, such as "Resident3723" at time 69069.

Running the scenario throws up a number of warnings relating to the arrival position being invalid. These aren't a concern for me (unless these are the cause of the problem) and are to do with the the plans being derived from a road network prior to conversion to SUMO's *.net.xml format.

Any help with resolving this would be much appreciated.

Thanks,

Greg
