Normalization of device probe data for path identification

Some embodiments provide a method for defining travel paths in a map region. The method identifies location data collected over a period of time from multiple mobile devices. The method aggregates the location data for each of multiple map areas. The aggregated data for each map area identifies an a...

Zusammenfassung:	Some embodiments provide a method for defining travel paths in a map region. The method identifies location data collected over a period of time from multiple mobile devices. The method aggregates the location data for each of multiple map areas. The aggregated data for each map area identifies an amount of mobile device traffic passing through the map area over the period of time. The method normalizes the aggregated data for a subset of the multiple map areas based on analysis of the relative amounts of mobile device traffic. The method uses the normalized data to identify paths in the map.
