Hello, 1) the 'pos' attribute contains the offset of a vehicle from the start of the current lane 2) the problem you encountered with traceExporter.py is hard to diagnose from your description. Please report the command you used (it needs to be run on the command line!) and report any errors that were printed 3) I cannot find the documentation about negative values to which you refer. Please give a link. regards, Jakob
