Abstract
A vehicle comprises memory for storing map data and a global positioning system (GPS) module that transmits vector and location data and that receives traffic reports from a remote traffic monitoring system. An adaptive map building module includes a path determining module that determines a travel path of the vehicle based on the vector and location data, a comparing module that compares the travel path to roads defined by the map data, and an identifying module that selectively identifies new roads based on the comparison.
