Algorithm of route searching based on adjacency list

A CAD application in an automatic test software of a computer is introduced based on interlocking.It also lays out a practical scheme that the test users can divide the signal graph of a railway station into diverse graph units efficiently,inputs the units conveniently and construct topologic data of a station graph based on an object oriented method.Finally,a particular description of a route searching algorithm is given based on graph data structure of an adjacency list.
