Thanks a lot! I found the solution. The problem was with the sumo version.
An old sumo version was not correctly converting co-ordinates. Sumo 1.1 is transforming between co-ord to lat long clearly ________________________________ From: [email protected] <[email protected]> on behalf of Jakob Erdmann <[email protected]> Sent: 04 May 2019 17:30 To: Sumo project User discussions Subject: Re: [sumo-user] Inquiry : Conversion from co-ordinate axis to Latitude and Longitude By using this <location> value, traci.simulation.convertGeo(x=50450.7527098387, y=22602.868908196364) returns (77.56111960623011, 13.008159137553312) However, the value 777805.9327098387, 1439436.2689081964 is the raw UTM-value corresponding to that location (the x,y value without the netOffset) Such a value would be returned by sumolib.net.convertLonLat2XY(77.56111960623011, 13.008159137553312, rawUTM=True)) I'm pretty sure there must be some other code in your script, responsible for that output because traci alone does not return nor accept raw UTM values.
