Training set and validation set division

[212wzt5A]

Hi Nuplan team, I saw that in the yaml file of the splitter, the log names of the training set, validation set, and test set are specified. I would like to ask how this data set is divided, such as by different areas of the city, or by time.

Additionally, the dataset page does not mention in which folder the test set belongs. I assume it belongs in the trainval folder as well since there is a dedicated splitter to handle the different splits. Nonetheless an explicit hint on the dataset readme would be useful.
