Abstract
Systems, methods, and apparatuses are described for total route scores to measure quality of map content. Test data is received for a region of interest. The test data may be matched to routes formed from road links stored in a database. Frequency weights may be assigned to the test data based on the frequency of usage for the road links. The routes in the database may be compared to the traveled routes in the test data. Using this comparison, one or more errors in the database may be identified. A total route score for the region of interest may calculated from the errors and frequency weights.
