Adding slope directions to an ITN network dataset.

I am currently attempting to test the feasibility of a navigation solution that can calculate the best route to a destination based on fuel economy variables. It is my intention to calculate an impedance value based on said variables. One of the variables I have selected is slope as a vehicle travelling uphill will use more fuel then one travelling downhill.

I have downloaded and imported into ArcMap 10.1 the Ordnance Survey ITN. However, I cannot seem to work out a way of getting slope direction from a raster underneath the roads and storing it in such a way that can be used for an impedance calculation.

I have a moderate amount of experience with ArcMap and some programming experience but I could really use the help of an expert!

Thank you,
