To calculate the total annual bus transportation miles for day students, a school must use the appropriate formula from this section. In the formulas, Tu = Miles driven on Tuesday of the transportation mileage count week, W = Miles driven on Wednesday of the transportation mileage count week, and Th = Miles driven on Thursday of the transportation mileage count week.
(a) For ISEP-eligible day students whose route is entirely over improved roads, calculate miles using the following formula:
(b) For ISEP-eligible day students whose route is partly over unimproved roads, calculate miles using the following three steps.
(1) Step 1. Apply the following formula to miles driven over improved roads only:
(2) Step 2. Apply the following formula to miles driven over unimproved roads only:
(3) Step 3. Add together the sums from steps 1 and 2 to obtain the total annual transportation miles.
