The distance along the great circle will then be s 12 = Rσ 12, where R is the assumed radius of the Earth and σ 12 is expressed in radians. Using the mean Earth radius, R = R 1 ≈ 6,371 km (3,959 mi) yields results for the distance s 12 which are within 1% of the geodesic length for the WGS84 ellipsoid; see Geodesics on an ellipsoid for details.
A vehicle miles traveled tax, also frequently referred to as a VMT tax, VMT fee, mileage-based fee, or road user charge, is a policy of charging motorists based on how many miles they have traveled. It has been proposed in various states in the United States including Illinois who are currently following through with implementing this tax, and ...
