Abstract: An embodiment may include, for a real world moving object moving along a real world path, modeling trajectory of the moving object along a polygon. The polygon may have a plurality of line segments and vertices and may represent the real world path for the moving object. A turn radius may be calculated at each vertex of the polygon. For a given vertex, the calculated turn radius may be associated with line segments of the polygon that originate from the given vertex. Using the calculated turn radii, a single-dimensional model may be formed of the real world path, where a respective calculated turn radius of the given vertex may serve as a measure of curvature of that portion of the real world path represented by the given vertex. The calculated turn radius of the respective given vertex may be defined by lane width of the real world path.

Abstract translation: 对于沿着真实世界路径移动的真实世界移动物体，实施例可以包括沿着多边形的移动物体的建模轨迹。 多边形可以具有多个线段和顶点，并且可以代表移动物体的真实世界路径。 可以在多边形的每个顶点处计算转弯半径。 对于给定的顶点，计算的转弯半径可以与源自给定顶点的多边形的线段相关联。 使用计算的转弯半径，可以由真实世界路径形成单维模型，其中给定顶点的相应计算的转弯半径可以用作由给定顶点表示的真实世界路径的该部分的曲率的度量 。 相应给定顶点的计算的转弯半径可以由现实世界路径的车道宽度来定义。
