API: Fraction in counts

I use this endpoint to export data:
https://telraam-api.net/v1/reports/traffic

The numbers are required per day, for the max. period of three months.
However, the format “per-hour” seems to be the only option, as far as I understand.

That is fine, I can combine it to get the numbers per day.

But the counted vehicles are in fractions. I can imagine that a car drives exactly in that hour switch in the street, but I expect that in a day all the an ordinal number of cars, trucks etc. pass the camera.

That is not the case. Why?

This is my request:
curl “https://telraam-api.net/v1/reports/traffic” --compressed -X POST -H “Accept: application/json” -H “Accept-Encoding: gzip, deflate, br, zstd” -H “Content-Type: application/json” -H “X-Api-Key: REDACTED” --data-raw “{”“level”“:”“segments”“,”“id”“:”“9000007626"”,““format””:““per-hour””,““time_start””:““2024-12-02 00:00:00Z””,““time_end””:““2025-03-02 00:00:00Z””}"

Indeed per-hour is the only option in the public api, per-quarter exists in the Advanced API. The fractions are a result of Telraam data being corrected for device downtime. See the “uptime” section at Understanding the Telraam API
