The math models of the tree structure chart and the net structure chart are formed by describing the different road state abstractly.The tree structure chart model is presented without consideration of U structure and ring structure. This kind of model has a notable feature: there is a line only between the two dot in the chart, which means that there is only one road from one point to another point in expressway ,so the tree structure chart is called "single roads chart".

在不考虑U型路段和环路的情况下，提出了高速公路的树状结构图模型，该模型具有一个显著的特点：图中两点之间有且仅有一条连线，这意味着由高速公路上的一个地点到达另一个地点仅有一条通路，也称这种高速公路树状结构图为"单路径图"；考虑到包含U型路段和环路的高速公路路况，提出了高速公路的网状结构图模型，这种模型可抽象成一个连通图，即图中任意两点之间至少有一条直线相连，这意味着由高速公路上的一个地点到达另一个地点有多条通路，也称这种高速公路网状结构图为"多路径图"。

Because of the fact, the bearing capacity of the whole drive cannot be developed well enough. To improve the performances of the load-capacity, transmission efficiency, and reliability of mechanical drive, we originally developed some designs of the double crank ring-plate-type cycloid planetary drive. The new-type drive keeps all the natural advantages, which is of multi-tooth mesh, small mesh angle, and hardened tooth flank of gears. Moreover, The drive does not need the special output unit as the ring-plate-type drive does, so that the rigidity of the output shaft becomes much higher. Since the tumbler bearing is placed outside the cycloidal gear, the size of the bearing is no longer restricted to any extent.
