Abstract:
1. A method for determining exceptions from a recommended route in a navigation application, comprising: providing to a computer assisted navigation system a recommended route for a vehicle to travel from a first location to a second location; monitoring a location of the vehicle when the vehicle is traveling from the first location to the second location; determining that the vehicle has deviated from the recommended route; determining if the deviation from the recommended route is one of a set of expected deviations by examining a set of rules associated with the monitored location of the vehicle; querying, by a dispatcher located remote from the vehicle, a driver of the vehicle when the deviation from the recommended route is different than the one of the set of expected deviations; receiving a response from the driver of the vehicle indicating that the recommended route is not an optimal route; and generating an exception notification based on the response from the driver of the vehicle.
