Dear All, I have a couple of question on the tripinfo [ https://sumo.dlr.de/docs/Simulation/Output/TripInfo.html]
1) Is it possible to enable or disable the tripinfo device [ https://sumo.dlr.de/docs/Developer/How_To/Device.html#msdevice_tripinfo] using traci? I need the tripinfo data only from a subset of vehicles and people (the one I'm creating and inserting on the fly) in a very large simulation. 2) I'm using the lxml python library to process the tripinfo file as it's done in xml2csv.py. When I'm enabling the validation using the XMLScchema provided in https://github.com/eclipse/sumo/blob/master/data/xsd/tripinfo_file.xsd i get error such as "lxml.etree.XMLSyntaxError: Element 'walk', attribute 'duration': [facet 'minInclusive'] The value '-1' is less than the minimum value allowed ('0')." This kind of errors are happening with and without the option "tripinfo-output.write-unfinished" enabled. I don't think that this is how it sould work, otherwise I don't see the point tin the XML validation at all. I cannot attach the tripinfo output because it's too big, but I can send it if someone is interested. Anyway, entries like this are the issue: <personinfo id="4283341_4283342_72" depart="29986.40" type="pedestrian"> <ride waitingTime="-1" vehicle="4283341_4283342_72_tr" depart="-1" arrival="-1" arrivalPos="50.07" duration="-1" routeLength="1.00"/> <walk depart="-0.00" departPos="50.07" arrival="-1" arrivalPos="44.18" duration="-1" routeLength="215.75" timeLoss="0.00" maxSpeed="1.27"/> <stop duration="0.00" arrival="-0.00" arrivalPos="44.18" actType="P-D"/> <walk depart="-0.00" departPos="44.18" arrival="-1" arrivalPos="50.07" duration="-1" routeLength="215.75" timeLoss="0.00" maxSpeed="1.27"/> <ride waitingTime="-1" vehicle="NULL" depart="-1" arrival="-1" arrivalPos="64.61" duration="-1" routeLength="-1.00"/> <stop duration="0.00" arrival="-0.00" arrivalPos="64.61" actType="Home"/> </personinfo> It's generated using Eclipse SUMO Version v1_3_1+0653-4280adad30. Thank you in advance for your time. All the Best, Lara
