comment How to make a routable graph from a Point and a Line shapefile, using Networkx?
Great! The problem is that this intersection node is somewhere in between 2 ends of an existing edge (unless it's itself endpoint). So the best thing would be to break the edge somehow at that point, so that it becomes "attached" to the graph, and hence routable.

But it does it implicitly, and it does not calculate the length of this connection link, which can be pretty critical in many cases.

@scw I modified the answer your answer and it works (well, sort of). The problem is that the connection link is a "dangling" link; not connected to graph. so i have to add an edge between intersection node and line-end, but still is pretty good. please post your answer below, then I can accept it.Thanks!

@scw True. but I have two shapefiles, i.e. two different graphs. I need to somehow connect the two

@underdark I've worked with that library before. It does allow to attach nodes to graph, but it doesn't contain as many functions as networkx has, and pre/post processing steps make it usually considerably slower, when you consider the whole program. I would like to stick to networkx if possible.
