Detailed Description

Author

mrieser

Calculates the distribution of legs-durations, e.g. how many legs took at most 5 minutes, how many between 5 and 10 minutes, and so on. Also calculates the average leg duration. Legs ended because of vehicles being stuck are not counted.

reset()

void org.matsim.analysis.CalcLegTimes.reset

(

Gives the event handler the possibility to clean up its internal state. Within a Controler-Simulation, this is called before the mobsim starts.

Parameters

iteration

the up-coming iteration from which up-coming events will be from.
