Hi, I have a student with a research problem that I need some help with.

Student has a basic road network with various road classes from minor up to Interstate. He wants to create an adjacency or connectivity matrix between major nodes along the interstates, across the entire network. His goal is to assign to the major nodes the total number of connections or possible routes between them, and the sum of the vehicle capacity of all those connections.

I've looked at Network Analyst and the schematics tools. I haven't worked with either before and the they don't specifically seem to do anything like this but can't be sure. Any ideas on tools or workflows to follow for this?

Thanks,
David

Can you be more precise on what you want in the matrix?

That is, for a list of (major) node locations, make a matrix of each node to every other such node with some value. This value is:
"total number of connections or possible routes between them"

Well this can be infinite.

So define it better and perhaps we can come up with a way to fill in the matrix.
