Incorporating Length of Route Value into Cost Evaluator Function

A friend and I are creating a walking network and we have run in to a snag. We would like to attribute a cost evaluator to our network dataset using a self determined safety metric. We have the equation set up so that all we need to do is divide a field value based on the length of a route to get our "safety value". We just need to know in the cost field how to write the vb script or other evaluator so that Cost Value=[FieldValue]/"total length of individual route". Each route length will be different once each analysis is run, but we have a length value for each line segment, so we know there should be a way that adds up these pieces for the route for a total route length that can be divided by our field value. It seems like it should be a simple script line or something to put in the field evaluator box. Any suggestions?

We are using Arc10.
