Abstract

A traffic monitoring system comprises memory for storing map data, a traffic report generating module that receives vector and location data from at least one of cellular phones and vehicles and that generates and transmits traffic reports based on the vector and location data. A map monitoring module includes a path determining module that determines a travel path of the at least one of the cellular phones and the vehicles 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.
