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
- Z values
- A constant speed of 25 kph
- 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.
