Investigating how Network Analysis can be manipulated to account for the slope/aspect

Hello folks new to the forum and just learning about network analysis now so pretty new to this too.

I've been set the task above and identified that i also need to consider the Cost Restriction, Direction of Travel, how to get the raw data in to a feature class and the different slope classifications which vehicles can traverse.

So far I am thinking this:

1) Each edge representing the road layer must have a TF or FT slope value. I can't figure out how i would give each edge a slope value representing that of the ground. I have elevation data and a road layer. Any Ideas?

2) A restriction could be used with to stop particular vehicles traversing roads which have a slope greater than the vehicles maximum slope.

3) Oneways can be utilised as normal in the restrictions tabs.

Thinking about it, the main problem i have is converting the raw data into an attribute or feature class which can be used to show any impedence that a slope will have upon a road edge.

Any help will be greatly appreciated!

Thanks in advance.
