  • Thread-topic: Use of minGap and Tau
Hello,

According to the SUMO documentation on vehicle definitions, both minGap (default = 2.2m) and Tau (default = 1s) are used to determine a vehicle's headway.
Is there a reason why both properties should be used while driving to characterize a realistic driving behavior? 

To my understanding, using both minGap and Tau would make the headway larger than the realistic value since they both contribute to determining the headway.

Should tau only be used while vehicles are moving whereas minGap should be only used while vehicles are standing?
If so, should they be muted (or be assigned with a value close to 0) for the vehicle status that is not applicable for them?

Thanks,
