[sumo-user] What does 'pos' mean in statistics net dump?

[Camillo S <mssyli009@xxxxxxxxx>]

Hi SUMO team,

I just want to make sure I understand the meaning of this in the statistics net dump file.

<vehicle id="vehicle_1" pos="8970.47" speed="30.00" posLat="2.35" speedLat="0.00"/>

does 'pos' mean the position in terms of meters from the starting position? does this mean that this vehicle is at position 8970.47 meters from the starting point?

Another question is, is it possible to use the statistic net dump file to calculate traffic density at every timestep? How is this done?

Thanks,

Camillo
