Abstract
A method for collecting data for a geographic database is disclosed. Speed and position data are collected using a plurality of mobile computing platforms moving in a geographic region. The speed and position data are analyzed to identify a location of a recurring delay point corresponding to a change in the speed. The geographic database is updated to indicate the location of the recurring delay point.
