(2)拟订轮廓方案根据已掌握的资料,先确定下列各点: 1.掌握运输主流方向输出和输入,形成地方道路网的运输主流。但在一个计划区域内,可能有一个(图6),箭头指输出流向,下同)或更多的运输主流(图7)。每一个运输主流的方向,可能聚于一点(图6),也可能趋于几个点或一条线(图8)。决定运输主流方向,应结合两项原则,即:(一)趋向于需要,(二)趋向于捷便(交通便利的方向)。关于这方面的依据,应参考各地区(省、自治区或以上的范围)的交通远景规划。
(2) Formulate the outline plan Based on the available information, first determine the following points: 1. Grasp the transportation mainstream direction of the output and input, the formation of local road network transport mainstream. However, within a planned area, there may be one (Figure 6), the arrow refers to the output flow, the same below) or more mainstream transport (Figure 7). The direction of each transport mainstream may converge (Figure 6) and may also tend to be a few points or a line (Figure 8). The main direction of transport decisions should be based on two principles, namely: (a) tend to be in need, (b) tend to be convenient (easy to transport). Reference should be made to the traffic scenarios for each region (province, autonomous region or above) on this basis.
