Outline of Final Research Achievements

The current focil fuel tax for road users has been accepted by public because it basically follows the beneficiary-pays principle. This taxation, however, will deviate from the principle when electric vehicles (hereafter EVs) reach masses. Toward the electric vehicle era, therefore, new policies such as road user charge system are needed.
In this study, we analyzed proper toll amounts according to congestion levels, publically acceptable schemes, and EVs future demand. The results show that proper toll amounts of expressway to reduce congestion are -10 JPY for terminal charge, +5 JPY/km, and -17 JPY/km for distance charge in congested and non-congested road, respectively. Secondly, it was found that using the money from the road user charge for road maintenance raises the acceptability of pricing scheme. We also found that EV's demand is higher in suburban areas than city center.
