Setting up a Road Fund in a Commercialised Road Sector

The key questions that are regularly asked about these road funds are: (i) is this simply earmarking under another name; (ii) can road users afford to pay the extra charges required to support additional road expenditures; (iii) how do these arrangements affect income distribution (i.e., do they simply benefit better off road users at the expense of the rest of the population); (iv) how do the arrangements affect inflation; and (v) why do you need a broad-based, public-private oversight board?
