Telenav is making use of its internally sourced, fully anonymized database of vehicle navigation probe trace data to enhance the quality of the OSM map. These probe trails are matched directly to updated extracts of the OSM map. From this a variety of enhancements are underway. Free flow speed and probe trail count analysis suggests highways that should be substantially upgraded or downgraded from their current tagging, particularly in areas that have received limited data attention. Vehicle routing turn restrictions can be inferred from probe trail statistics. Since these results are often challenging to verify and validate, the results of these and similar efforts can be channeled through MapRoulette for verification and application to the OSM map. These enhancements will widen community use of and involvement with OSM by enhancing the navigation quality information within the map.
