Abstract:
1. A computer-implemented method for estimating travel times between vehicle locations by a vehicle navigation system, the method comprising: receiving, by a navigation server, a first route request from a telematics unit wherein the first route request contains a destination, a first time-of-day and a first location of a vehicle; receiving, by a navigation server, a second route request from the telematics unit wherein the second route request contains the destination, a second time-of-day and a second location of the vehicle; calculating, by a navigation server, a travel time between the first location of the vehicle and the second location of the vehicle using a difference between the first time-of-day and the second time-of-day; averaging, by the navigation server, the calculated travel time with other calculated travel times between the first location of the vehicle and the second location of the vehicle to render an averaged result; and storing, by the navigation server, the averaged result as an estimated travel time between the first location of the vehicle and the second location of the vehicle in an electronic database.
