Method and system for determining a stress index of a route

A vehicle, comprising:

• a navigation system for navigating a route, wherein the navigation system comprises a processor and memory with instructions stored therein, wherein the instructions include instructions for determining, based on a cartographic representation, at least one route from a first point to a second point;
• dividing, by a stress index determination system, the at least one route into one or more links and/or intersections;
• determining, by the stress index determination system, the stress for the at least one or more links and/or intersections;
• and combining, by the stress index determination system, the stress of the one or more links and/or intersections to obtain an overall stress index of the one or more routes, wherein the link is a road segment having substantially constant road properties along the road segment and the stress of the link is determined based on a complexity of the link, wherein the complexity of the link is determined based on attributes of the link that are indexed based on a type and provide a resulting coefficient;
• and
• a display to display the overall stress index.
