How to calculate slope direction in Network?

Hi!

 

My goal is to calculate the fastest biking rout to school with network analyst. In the calculation I want to also include the cost of biking up/down a slope.

I think I have all the necessary information for each road segment

- Slope

- Z values

- A constant speed of 25 kph

- Meters

- Seconds it take to travel each segment

 

I also have FT_Seconds and TF_Seconds so that I could do Evaluator on the time when going up/down a slope.

 

The problem is that I don't know how to make the calculations for the FT/TF attributes, how do i calculate so that it knows the slope is Up or Down?

 

I had some ideas of when traveling, if the next road segments mean Z value was higher then the slope would be up. and vice versa for going down.

 

What and how will I write it in the field calculator?

 

I know there is threads of this before, but what I have found non explains how to do the calculations.

 

 

Thanks.
