The data must be extrapolated if it is to be used for predictingfuture traffic Anna NagurneyFOMGT 341 Transportation and logistics - Lecture 1US Interstate Highway Anna NagurneyFOMGT 341 Transportation and logistics - Lecture 1 Transportation Planning ProcessPhase II - Model BuildingInterested in finding out relationships among parameters of categories of relationships1.
