WSA EM1, 1-cent/mile: Wilbur Smith Associates (WSA) estimates of impacts of emissions-weighted vehicle miles traveled (VMT) charge, all roads, average charge: 1 cent per mile. EM2, EM3: same as EM1, but with 2 and 3-cent/mile charges.

WSA CP1, freeway only: WSA estimates of impacts of 5-10 cents/peak mile congestion charges, freeways only.

WE CP3+, all roads: WSA freeways-only 15-30-cents/peak mile congestion charge impacts extrapolated to all roads.

D-H Mod-Impact Combination: Deakin-Harvey "moderate-impact" combination of 15 cents/peak mile congestion charge, all roads; 1-cent/mi emissions charge; $1/day parking charge; 50-cent/gallon fuel surcharge.

WSA CP2, EM1: 10-20-cents/peak mile congestion charge, freeways only, 1-cemt /average mile emission charge, all roads.

WSA CP2, EM1, ET: Same as above, but with $12.5 billion worth of extra "enhanced" transit.

WE CP3+, EM1: WSA 15-30-cents/peak mile congestion charge, extrapolated to all roads, 1-cent/average mile emission charge, all roads.
