I am currently creating service areas at 1600m. I want to add a point and line barrier as an added cost. I have done this but I am unsure of the calculation that is being used in the service area tool, i.e., if i say that the line barrier increases distance by 100m and I put 100m in the cost field, does this get multiplied by the line length?

I have looked through the help and forums but I can't find an answer to how the added cost is calculated with the service area anywhere.

Any help or direction would be great!!
