Method for influencing source data for determining a route in a navigation system

摘要

A method for manipulating source data to determine a route from a predetermined starting point to a predetermined destination for a means of conveyance, in particular for a motor vehicle, airplane or ship, based on a digital database that includes predetermined route segments k_i with correspondingly assigned nodes n_i that interconnect respective route segments k_i, where respective weights g_i are assigned to the route segments k_i and/or the nodes n_i. The weights g_i are varied, as a function of external events, before a route finding algorithm determines the route.
