[Routing] Time dependent/live traffic map data

[Josh Doe]

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!
