Abstract

According to a method for creating a model for a travel time database, a leg network comprising leg sections between a starting point and a destination point are analyzed. Multiple routes are ascertained between the starting and destination points. Each leg section of a route is associated with a relative travel time loss and is weighted. The ascertained travel time losses and the associated weightings are used as input data for a learning method by way of which an existing knowledge base is iteratively expanded.
