Abstract
A system and method is provided for identifying and generating a route that provides a driver with an exhilarating ride. In an example method, the navigation system obtains location data for routes between a starting and ending location. The location data is analyzed by identifying points of inflection of the curved road portion. At least one curved segment is identified as being road portions between the points of inflection. A linear distance, Llinear, is measured between the points of inflection of the at least one curved segment. A curve depth, H, is measured by identifying the maximum distance between the line between the points of inflection and any point on the curved segment along a perpendicular to the line between points of inflection. A curved segment degree of curviness=H/Llinear is calculated and used to determine the measure of curviness of the route.
