How to use different SUMO map skenario in ms-van3t?

[ketutbayu]

Greetings,
Thanks so much for developing this amazing ns3-v2v-v21-v2x platform. I try to use my own map and customize the code in v2v-emergencyvehiclealert-80211p. cc but I have this error:

Reading the .rou file...
I/O warning : failed to load external entity "/home/bayu/sumo/tools/peta-bundaranosm.passenger.trips.xml"
msg="Error: unable to parse the specified XML file: /home/bayu/sumo/tools/peta-bundaranosm.passenger.trips.xml", file=../scratch/v2v-emergencyVehicleAlert-80211p.cc, line=152

is it possible to customize the map/traffic map scenario using our setting generate by openstreetmap in default ms-van3t?
or Can I edit the default map generated by ms-van3t and how to edit it?

Thank you

Regards,
