Hello, SUMO needs Cartesian coordinates to work but there are various features for converting back and forth between UTM and the original WGS84 coordinates - SUMO-GUI shows lon,lat - fcd-output can be configured to export lon,lat - shapes with lon,lat coordinates can be loaded directly into SUMO - TraCI can convert between coordinates - the python library sumolib offers coordinate conversion.
For pruning the network, consider the option --keep-edges.by-vClass or --keep-edges.by-type (http://sumo.dlr.de/wiki/NETCONVERT#Edge_Removal) regards, Jakob 2016-01-22 11:36 GMT+01:00 ax487 <[email protected]>: > Hello everyone, > > I am evaluating sumo for a simulation designed to test a simplified > traffic model.
