  • Method and system for calculating a quantity for a route segment extending between two points on a digital map
    Patent number: 8620574
    Abstract: A method and system are provided for calculating a quantity for a route segment extending between two points on a digital map, the points corresponding to two geographical locations, the quantity representing a distance between the two geographical locations or an estimated time for travelling between the two geographical locations, the method comprising; determining a base quantity for the route segment, determining a first parameter corresponding to a first condition between the two geographical locations, determining a second parameter corresponding to a second condition between the two geographical locations, determining an additional quantity based on the first parameter and the second parameter such that the influence of the second parameter on the size of the additional quantity depends on the first parameter, calculating a modified quantity for the route segment based on the base quantity and the additional quantity, and generating a signal based on the modified quantity.
