apportionment formula

apportionment formula　分摊方程式　

individual apportionments to municipalities for the Consolidated Local Street and Highway Improvement Program[CHIPS]are calculated annually according to a formula specified in Section 10-c of the State Highway Law.The two most important data inputs for this apportionment process are local highway mileage（for all municipalities）and motor vehicle registrations（for counties and NYC）that are reported annually to NYSDOT.Each apportionment consists of two separate amounts that are authorized in two different subdivisions of Section 10-c.Subdivision 3of Section 10-c authorizes payments historically out of the Transportation Improvement Fund[TIF]，while Subdivision 4of Section 10-c authorizes payments historically out of the Local Assistance Fund[LAF].Consequently，any given CHIPS check generally reflects payments made out of both the TIF and the LAF.
