Cadyts – Calibration of Dynamic Traffic Simulations
Copyright 2009-2017 Gunnar Flötteröd
Cadyts estimates disaggregate demand models of dynamic traffic assignment simulators from traffic counts and vehicle re-identification data. The tool is broadly applicable in that it (i) makes only very mild assumptions about the calibrated simulator's workings and (ii) allows for various modes of technical interaction with the simulation software.

Cadyts has been successfully used to calibrate the following traffic simulators:
· DRACULA (Dynamic Route Assignment Combining User Learning and Microsimulation)
· The code is available on github: https://github.com/gunnarfloetteroed/java.
