Road Traffic congestion, resulting from the inadequacy of existing transportation infrastructure to transport people from various origins to various destinations, using the same paths, at the same time (without delay) is an issue of concern to humanity. Inadequate funding for transportation limits the number of roads that can be built to increase the capacity of the transportation network. Road traffic congestion pricing has been identified as a way of reducing congestion, as it makes the cost of travel more apparent to users, but there is concern about equity issues for those who may not be able to afford the price tag. This study used the records of vehicle miles traveled in a country to illustrate the variations in revenue that could be achieved with a varied fuel efficiency of vehicles. This review noted that the VMT ‘road user fee’ pricing system is a viable way to make the cost of travel apparent to motorists and form a basis for equity between those who use fossil fuel vehicles and those who use alternative energy. The study also presented a simplified method to estimate the appropriate fuel tax, as well as VMT road user fee to achieve a self-funded transportation system.
