Calibrating MatSim based on counting points #37

Closed ChristophTraf closed 5 years ago

ChristophTraf commented 6 years ago

We would like to calibrate our MatSim simulation based on several counting points which are irregularly distributed in our study area. The counting points related files include the number of vehicles which are passing a corresponding link. The measurements have a temporal resolution of 1 hour.

What is the best way to calibrate the simulation in that way, that the simulated hourly link volumes correspond to the measurements? Should we use the network capacity and speed as calibration parameters? Is there any existing tool to perform such sensitivity tests?

Thank you very much!

Calibration of Dynamic Traffic Simulations (Cadyts) is the answer to your question (created by Gunnar Flötteröd). Inside the following link you can find some more information/publications about Cadyts.
