Ever heard of the The World Bank Transport Activity Measurement Toolkit (TAMT) [1]? It's for modeling emissions, however part of this includes collecting GPS traces to generate travel time and speed distribution by vehicle type and for different days/times. There's some more information available here [2].
They even use JOSM for tagging!
