Abstract
A method for improving and extending an existing road network and generating new networks from statistically relevant amounts of probe data recorded by GPS-enabled navigation devices. New probe data is matched to the existing digital vector map, then the data merged into the existing network using a weighted mean technique. When new roads are detected, appropriate junction points are made with the existing network elements. The updated network data is simplified to improve computing speed and reduce data storage requirements.
