This session will look at Traffic Locations, which will provide an OSM map based view of real-time traffic information for display and consumption. These locations are derived from a division and recombination of the more important highway classes. This process has created some unique insights and posed challenging questions regarding OSM data. For example, wide scale variations in OSM highway classification between some metropolitan areas becomes evident. While the primary motivation for Traffic Locations is to create and report real time traffic information, the development of this new resource can help stimulate further improvements to the OSM map.
