Method and system for calculating a quantity for a route segment extending between two points on a digital map

A system for calculating a quantity for a route segment extending between two points on a digital map, said points corresponding to two geographical locations, said quantity representing a distance between the two geographical locations or an estimated time for travelling between the two geographical locations, said system comprising:

• a base quantity determining device that determines a base quantity for said route segment, the route segment corresponding to a road segment extending between the two geographical locations;
• a first parameter determining device that determines a first parameter corresponding to a first condition of the route segment between the two geographical locations, wherein the first condition corresponds to a traffic flow along the road segment;
• a second parameter determining device that determines a second parameter of the route segment corresponding to a second condition between the two geographical locations;
• an additional quantity determining device that determines an additional quantity based on a combined effect of said first parameter and said second parameter such that the influence of said second parameter on the size of said additional quantity depends on said first parameter;
• a calculating device that calculates a modified quantity based on said base quantity and said additional quantity;
• and
• a signal generating device that generates a signal based on said modified quantity.

A non-transitory computer readable medium storing software for calculating a quantity for a route segment extending between two points on a digital map, said points corresponding to two geographical locations, said quantity representing a distance between the two geographical locations or an estimated time for travelling between the two geographical locations, the software comprising:

• executable code that determines a base quantity for said route segment, the route segment corresponding to a road segment extending between the two geographical locations;
• executable code that determines a first parameter corresponding to a first condition of the route segment between the two geographical locations, wherein the first condition corresponds to a traffic flow along the road segment;
• executable code that determines a second parameter of the route segment corresponding to a second condition between the two geographical locations;
• executable code that determines an additional quantity based on a combined effect of said first parameter and said second parameter such that the influence of said second parameter on the size of said additional quantity depends on said first parameter;
• executable code that calculates a modified quantity for said route segment based on said base quantity and said additional quantity;
• and
• executable code that generates a signal based on said modified quantity.
