Rijkswaterstaat makes monthly data on the maximum speeds available on the Dutch road network. Two files are delivered: one for the main road network (WEGGEG), one for the underlying road network (WKD).
New versions of both data collections are available every first week of the month. The files are available through the open data portal of NDW: http://opendata.ndw.nu
