路径规划有很多算法，在导航中，经常提到的就是 Dijkstra 算法和 A* 算法， Dijkstra 算法，中文译名为迪杰斯特拉算法，是由荷兰计算机科学家狄克斯特拉于 1959 年提出的。从一个顶点到其余各顶点的最短路径算法，解决的是有向图中最短路径问题。迪杰斯特拉算法主要特点是以起始点为中心向外层层扩展，直到扩展到终点为止。 There are many algorithms for path planning. In navigation, Dijkstra and A* algorithms are often mentioned. Dijkstra The algorithm, translated in Chinese as Dijkstra algorithm, was developed by Dutch computer scientist Dixtra in 1959.

Sudden extreme weather will affect the normal running of the vehicle, and it is very likely to cause traffic accidents. We should try to avoid such weather when we travel.
