count scale factor in sample simulation resulting in similar outputs #823

Open aayushtewari01 opened 1 year ago

aayushtewari01 commented 1 year ago

I have been testing 10% sample simulation with a Count Scale Factor of 10. BUt when I compare the output of case 1: Sample population 10% with count scale factor = 10 & case 2: Sample population 10% with count scale factor = 1 The link traffic count is exactly similar. Can someone please guide me to where am I wrong? Attached is the config file of both settings. Thanks hoping for an early response. config CSF =1.txt config CSF =10.txt

@Janekdererste Sorry to ask, but if you can please check and suggest. I am really stuck in this and need it to be resolved for further research. Thank you

The countsScaleFactor within the counts config-group has no influence on the linkStats file that is written by MATSim.

The counts module requires an input file containing data from real-world counting station on selected links. The simulated counts are then scaled with the specified factor and compared against these real-world data.

As you have no inputFile specified for the counts, the parameter is basically ignored.
