摘要： Techniques and systems are disclosed that provide for creating an accurate representation of a roadway network, such as for planning vehicle travel routes. Positioning data is obtained, such as GPS data points from a plurality of vehicles, which mark traces of vehicular travel. A location of a trace is clarified using adjustment forces that are related to the traces, for example, to form coherent groups of traces. From these groups of clarified traces, a graph line is created by merging the traces.
