Methods and systems related to determining an order and/or location of driving lanes on a road segment are disclosed. In some embodiments, this may include using, for example, a degree of similarity or other suitable metric to obtain and cluster pavement profiles associated with a road segment. The position or lateral offset of the longitudinal section of the cluster may be used to determine the lane order and/or position. The resulting lane-specific information may be used to determine a driving lane of the vehicle by comparing road profile information associated with different lanes to a current road profile obtained from the vehicle. In other embodiments, methods and/or systems for enhancing global navigation satellite system (GNSS) signals may include determining a lateral offset using an original GNSS signal and a GNSS location associated with terrain-based data for determining a corrected GNSS location of a vehicle.

    公开了与确定路段上的行驶车道的排序和/或位置相关的方法和系统。在一些实施方式中,这可以包括使用例如相似程度或其他适当的度量来获得并聚类与路段相关联的路面纵断面。聚类的纵断面的位置或横向偏移可以用于确定车道排序和/或位置。所得到的车道特定信息可以用于通过将与不同车道相关联的道路纵断面信息与从车辆获得的当前道路纵断面进行比较来确定车辆的行驶车道。在其他实施方式中,用于增强全球导航卫星系统(GNSS)信号的方法和/或系统可以包括使用原始GNSS信号和与基于地形的数据相关联的GNSS定位来确定横向偏移,以用于确定车辆的经校正的GNSS定位。
