Obtain total travel programmatically

Hi everybody,

I am trying to get access to the total travel distance traversed by a transporter and I know that it appears in the statistics. I assume that almost all what can be seen in statistics tab must be stored on the object somewhere at some node or label.
but in the statistics part of tree edit window of the transporter I do not find such item and I cannot find any command in the manual to get this value directly or indirectly.

This I need to make a post-simulation report in certain format for import in another software.

Any constructive comment is appreciated.

Under the state_profile node there is travel_empty, travel_loaded, offset_travel_empty and offset_travel_loaded. I'm not sure if these values represent time or distance though.

getvarnum(<traveler>,"totaltraveldist")
