The council may likewise in the case of communication companies collecting tolls for both local and out-of-city business, interurban transportation companies and other companies as to which practical difficulties may arise as to the segregation between local and other tolls, fares or charges, provide for a segregation as between such local and other tolls, fares or charges. In franchises covering operations as to which the requirement of payment of a percentage of gross receipts is not practical, the council shall fix a basis for computing the franchise payments, if any, to be paid by grantee.
