为减少节点拓展数量，这里对交通路径网络中所有有向节点对进行预处理，增加最优标志属性，该属性记录有向节点对是否在到达各个块的最优路上。计算有向节点对最优标志如图 5-1 所示。

結果 (英文) 1:

To reduce the number of nodes to expand, here for all nodes in the network traffic path for pretreatment increase the optimal symbol attribute, the property records to block of the node to reach the optimal way. Computing the nodes for optimal symbol as shown in Figure 5-1.

結果 (英文) 2:

To reduce the number of nodes to expand, where all the traffic route network nodes have to be pretreated to increase the optimal mark property, which records whether a node has to reach all blocks in the optimal way. Directed computing nodes as shown in Figure 5-1 for the best mark.

結果 (英文) 3:

In order to reduce the number of nodes expanded, here traffic paths in the network have to all nodes on the pretreatment, increase the optimal symbol attribute, the attribute record to achieve optimal node on whether in each block on the road. To compute nodes on the optimal symbol as shown in figure 5-1.
