In the walking network that a friend and I are creating, we want to calculate an overall safety rating for each route. Each segment of our walking network has a certain safety value. We have calculated a "total safety" rating of each segment by multiplying the length of the segment by the safety value of the segment (1 to 5). When creating walking routes using Network Analyst, we want to be given the sum of all the "total safety" ratings for all the segments along the route. Using this, we can normalize this value by the total distance, giving us an overall safety value for the entire route.
Does anyone know how to do this?
