None of the sumo tools which convert counts to routes take into account the timing effect within a single route (i.e. a vehicle registers at one counting location in the first time interval and then, due to driving time, registers at the next location in another time interval).
This means there will be issues if the following two conditions are met:
- the demand changes sharply from one time interval to the next
- the travel time of a route is higher than the duration of a time interval

Assuming your routes have an average travel time of 1200s and you need to match a 300s profile,
you could try a combination of using routeSampler with option --interval 1200 and combine this with calibrators that use the 5min data.

Yes, it is about more fine-grained timing profiles (5 minutes).

Thanks,

Teleports / jamming can have many causes.
Routesampler is able to generate traffic that follows a time-profile (i.e. hourly counts) if the input data defines multiple time intervals.
Or is this about more fine grained timing profiles?

Hello, 

I'm trying to calibrate a simulation without having a lot of teleports. the original route file contains about 132k routes. When I use sumo's calibrator or routesampler, the profile of the departure times changes. My goal is to calibrate the simulation without changing the profile and without having a lot of teleports. Do you have any idea about this problem, please?

Thanks
