Elevation off road

i'm using the Modelbuilder in ArcGIS 10.1 to calculate pixels depending on their slope and distance from the road. The third necessary task is to find out, if the pixel is upwards the road or downwards. Is there any fast solution to do this. The question sounds simple but in ArcGIS i have no idea to that.

My first steps are:
Do Cost allocation from roadpoints and slope, getting areas which would be accessable from the roadpoint, then interpolating z value to each area, calculating the mean height and compare it to the height of the streetpoint value! This is a really dirty way to do so and i would be thankful for any help
