Speed histogram is only for cars?

Hello, I’m trying to analyze some data from your API.
I’ve understood that there is no speed data at night.
I see that there is two parameters (with two different “resolutions”), car_speed_hist_0to70plus and car_speed_hist_0to120 (more detailled).
But are those histograms only for cars or for all entries ? Because that would make no sense to have the car speeds but not the trucks.

thanks !

Hi Gordie

You can read all about the S2 speed calculation here:

We only calculate the speed of objects classified as cars. We are not measuring the speed of individual vehicle objects (this is not a speed camera and detector) but rather deriving and calculating a speed for objects of roughly reliable length. This is not possible for trucks, and so the speed is for cars only
