Hi Sharif,
 
do you actually need to retrieve this information during the simulation? If 
not, consider using TripInfo
<https://sumo.dlr.de/docs/Simulation/Output/TripInfo.html> output.
 
Best regards

Hi Mirko,
 
Thanks for the information. So, is there any other method to calculate the 
total distance traveled. I may run the traci.vehicle.getDistance(VehID) 
every time step and store only positive values but this will be 
computionally expensive. 
 
Best regards,
Sharif

Hi Sharif,
 
this happens when a vehicle is currently out of the road network. You get 
INVALID_DOUBLE_VALUE = -1073741824.0 returned. The taxi might be parked / 
pick up a passenger. In this case, the distance cannot be calculated 
because  e.g. a parking lot can be placed freely in the net without caring 
much about its access lanes.
 
Best regards
Mirko

Hi, 
 
I am using traci.vehicle.getDistance(VehID) to calculate the total distance 
traveled by taxis. For some of the taxis, I get a very large negative 
value. As I have a fleet of taxis so the number of getting invalid numbers 
changes every time I run the simulation.
 
Thanks for the assistance.
 
Best regards,
Sharif
