    • 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.
    • 提供了一种系统和方法,用于识别和产生为驾驶员提供令人振奋的骑行的路线。 在示例性方法中,导航系统获取在起始位置和结束位置之间的路线的位置数据。 通过识别弯曲道路部分的拐点来分析位置数据。 至少一个弯曲段被识别为在拐点之间的道路部分。 在至少一个弯曲段的拐点之间测量线性距离L linear。 曲线深度H通过识别弯曲点之间的线之间的距离和弯曲部分上的任何点之间的最大距离来测量,该距离沿着与拐点之间的线的垂直线。 计算弯曲曲率曲线度= H / L线,并用于确定路线曲线的度量。
