1 Summary of Potential Target Formula Scenarios Scenario 1: Current Target Formula Distribution Scenarios Substituting Measures Scenario 2: Substituting Lane Miles at PSR<3 for All Lane Miles Scenario 3: Substituting Bridge Area, over 20 sq. ft. at SR<50 for All Bridge Area over 20 sq. ft. Scenario 4: Substituting Lane Miles at PSR<3 and Bridge Area SR<50 for Lane Miles and Bridge Area Scenario 5: Substituting Congested VMT (using IRC Thresholds) for All VMT Scenario 6: Substituting the above three variables as defined, Keeping Buses, Future Population and Heavy Commercial VMT as in Current Formula State Transportation Plan Scenarios Scenario 7: -Based / State Transportation Plan Targets Scenario 8: -Based / Management System Needs Scenario 9: -Based / State Transportation Plan Targets & / Scenario 10: -Based / Management System Needs & /

Measures, 2002 VMT (4) Daily Vehicle Miles of Travel from TIS, September 2, 1998 HCVMT (4) Daily Vehicle Miles of Travel from TIS, September 2,

4 Scenario 5: Target Formula Distribution Substituting Congested VMT For All VMT sy Bridge Area 1 Lane Miles 2 25% VMT Congested VMT 4 25% Bridge (1) Mn/DOT Bridge Inventory, all bridges 20 feet and over, September 1, 1998 TIS, September 2, 1998 (4) Congested VMT on all roads, using the IRC threshold of above medium level of Congested VMT congestion for each road type. HCVMT (4') Daily Vehicle Miles of Travel from TIS, September 2, 1998 Scenario 6: Target Formula Distribution Substituting Bridge Area SR<50,Lane Miles PSR<3 and Congested VMT sy Bridges 1 2 (PSR < 3.0) 25% VMT Congested VMT 4 25% (1) Mn/DOT Bridge Inventory, all bridges 20 feet and over, Using area with SR<50, Bridge Bridge Measure, 2002 TIS, Using Miles with PSR<3.0. Measures, 2002 (4) Congested VMT, using the IRC threshold of above medium level of congestion Congested VMT for each road type. HCVMT (4') Daily Vehicle Miles of Travel from TIS, September 2,
