Exporting an Adjacency Matrix from a Network Dataset

Hi all,

First, an adjacency matrix is defined as: the adjacency matrix of a finite graph G on n vertices is the n ?? n matrix where the non-diagonal entry a_ij is the number of edges from vertex i to vertex j. In this case, the a_ij values will only be 0 or 1.

Disclaimer: I am completely new to ArcGIS.
Problem: I am interesting in exporting an adjacency matrix from a network data set.

Thus far, I have converted my polyline ZM road network into a network data-set using ArcCatalog 10.2 and the network analyst toolbox. This yields a graph with vertices and edges. Now, I believe I need to use the OD Cost matrix with some modifications in order to extract the adjacency matrix but I am not sure how to go about this. Is it possible to accomplish this in ArcMap 10.2 alone or will I need to use a python script?

Any help would be greatly appreciated!

Thank you,
-J
