For the Netherlands, this data is available from the NDW, a cooperation of traffic management of various local and regional entities.
The data is available both real-time and (limited) historical.
The full historical data seems to be available but not as (fully) open data, as they ask you to do something that 'improves traffic flow or traffic safety' in return. Examples they give are: provide them with more data, do a quality control of their data, or making it easier for the public to use the data.
The latest data is available here: http://opendata.ndw.nu/
Unfortunately, most of the documentation seems to be in Dutch only: https://www.ndw.nu/documenten/nl/#cat_2
They also have a portal to download a limited selection of the historical data: https://dexter.ndwcloud.nu/opendata
If you want more data, you should contact them as they seem eager to cooperate.
(Note that this dataset is also included in the list provided in user149408's answer to this question, so make sure to give their answer an upvote as well if you liked mine!)
