Abstract

A system and method for predicting a route to be authorized by a dispatcher for a vehicle to travel on a route network comprises a computer system that has a database having stored data relative to interconnecting route segments that make up the route network. Data relative to the origination location and the destination location is input into the computer system. The processor accesses the database and generates a predicted route with an origination location and destination location.
