This could be caused by re-labeling of the nodes from the order of their
first appearance in the trace file. To avoid re-labeling use the
traceExporter option --orig-ids (but make sure that all vehicles have
numerical ids then).

>>> Hello,
>>>
>>>
>>> I was trying to have vehicles running with a constant speed and a fixed
>>> intervehicle gap with the vehicle 0 is the leader and 5 others vehicles
>>> following it in respect to their ID order. I followed the steps in here
>>> <https://sourceforge.net/p/sumo/mailman/message/36036344/>
>>> and could see in sumo-gui that the vehicle gap is fixed and quite small.
>>>
>>> The problem is that when I export the trace to ns2mobility format and run
>>> an application in ns3 that computes the distance between node 0 and the
>>> others nodes, I see that node 2 is much more closer to the node 0 than
>>> node
>>> 1 which is not the case in sumo-gui where vehicles are moving in the good
>>> order.
>>>
>>> Note : I use sumo-0.24.0 and  after using the command traceExporter.py
>>> --fcd-input trip.xml --ns2mobility-output mobility.tcl -b 0 -e 3000
>>>  I get the ns2 tracefile where I change node (0.x)--> node (x).
>>>
>>> Can someone please help know the reason of that ?
