    • The present invention provides a system, a method, and a computer usable medium that includes a program, for generating navigation instructions for a vehicle. This may be done by determining whether a first proximity area associated with a first maneuver point overlaps with a second maneuver proximity area associated with a second maneuver point and determining whether a first vehicle location is within the first proximity area. It may also be done by determining a first distance between the first vehicle location and a zero point associated with the first maneuver point and determining a second distance between a second vehicle location and the zero point associated with the first maneuver point. It may also be one by truncating the first proximity area based on a comparison of the first distance and the second distance.
    • 本发明提供了一种系统,方法和计算机可用介质,其包括用于生成车辆的导航指令的程序。 这可以通过确定与第一操纵点相关联的第一邻近区域是否与与第二操纵点相关联的第二机动接近区域重叠并且确定第一车辆位置是否在第一邻近区域内。 还可以通过确定第一车辆位置与与第一操纵点相关联的零点之间的第一距离并且确定第二车辆位置与与第一操纵点相关联的零点之间的第二距离来完成。 也可以通过基于第一距离和第二距离的比较来截断第一接近区域。
