What is the unit of travel time and speed in Veins?

I'm working on Veins in OMNeT++, by using TraCI commands to get the travel time of roads using this method: 

double getCurrentTravelTime().

The value which I get from this is very small. So I wondered what the unit of travel time is and also how to get the mean speed in SuMO or Veins?

Solution

  • This commands queries variable 0x5a from an edge. Its meaning is documented on the SUMO wiki, on page http://www.sumo.dlr.de/wiki/TraCI/Edge_Value_Retrieval:

    current travel time (0x5a): double, Returns the current travel time (length/mean speed).

    Where not specified otherwise, SUMO uses the international system of units, that is, the return value is in seconds.
