| Research Abstract |
This study is a comprehensive analysis of road policies based on microeconomics. The main results are as follows. First, the rationale for the special account for revenues earmarked for road construction is weak from microeconomics. Revenues from road taxes may be used in various ways. Especially, the investment in public transit by the revenues from road taxes, as implemented in London and Stockholm, possibly enhances the social surplus. Second, the road taxes are necessary to adjust the congestion externality. The simulation based on the data on Tokyo suggests that the level of road taxes is insufficient.
