The total estimated cost of replanking a single crossing is obtained by multiplying the estimated cost of replanking per track-foot by the width of the crossing. For the purposes of this calculation, “the width of the crossing” is the length of the track traversing the roadway plus 3 feet beyond the edge of the pavement or sidewalk on both sides of the roadway (a total of an additional 6 feet). The total cost includes the cost of replanking multiple tracks at the same crossing if multiple tracks are to be replanked.

The estimated cost per vehicle is the total estimated cost of the project divided by the AADT at the crossing. AADT is determined by an actual count if available or an estimated count provided by TPP. AADT is not determined based on a future projected count.
