K条路是在计算出一条最短路径后，继续计算几条次短路径。 多条路经可以为驾驶者提供多条路径选择，驾驶者可以根据自己的喜好选择路径。另外这些次短路径可以在最短路径阻塞时作为备选路经或应急路径使用。 计算中可以设定不同的条件来进行计算，如各路经共用路段多少，路径长度限制等。-K is the right route in the calculation of a shortest path to continue the calculation several times shorter path. Number of motorists passing by can provide multiple paths to choose and motorists can choose according to their own path. Also these times shorter path in the shortest possible path obstruction as an alternative path passing by or emergency use. Calculation of different conditions can be configured to carry out the calculation, such as the various sections by the number of shared, such as path length.
