| Abstract: | Noting the fixed positions of nodes and links and the orientation of searching the valid route and in addition,drawing lessons from the flowing characteristic of water drop in a field of gravity,a new way is proposed to intuitively find the shortest-route in transportation network.The assumptions in the new way,the basic applied steps and the ways of dealing with some special problems are expounded with its advantages and disadvantages discussed. |

| Keywords: | transportation network the best route and the second route searching the route of (orientation) (SRO) traffic assignment |
