Hi,

In Cadyts the route choice probabilities will be adjusted according the given flows and the routes, generated by DUAROUTER if you use SUMO-Cadyts. No vehicle parameters are considered in Cadyts.

 

Kind regards,

Yun-Pang

In case of cadyts, does it calibrate vehicle parameters as well? What things does it change to get as close to the real flow as possible?

SUMO includes no tool to perform callibration from this data in a principled way.

You could probably hack something up that does hillclimbing or random sampling with varying parameters (traffic amount or vType parameters) to approach your measurement data.

Is there a way to calibrate models if I don't have real flow values. Just travel time in different edges and routes during different timings?

 

Thanking you in advance,

 

Rony Gracious.
