A new model that can be used to make sufficiency ratings of secondary roads is described briefly. the calibration and scales used with the rating criteria are described in some detail, with particularemphasis on both the linear and the nonlinear features of the scales. the flexibility of the model, particularly with the use of variable standards, is noted. this feature makes it possible to prepare new priority rankings based on revised functional classification or design standards, or both, for local use. it is also suggested that the model could be used as an aid in developing new road use tax allocation formulas. it is concluded that, though many other factors needto be considered, use of the same model across jurisdictions would provide realistic statewide needs assessments. this paper appears intransportation research record no. 1156, transportation systems planning and management.
