Abstract
The purpose of this study is to simulate a congestion tax and a transit subsidy policy by CGE (Computational Generalized Equilibrium) model and to understand each policy’s effects on urban traffics, land use, people’s migration and air environment.
While we operate some traffic policies, they affect not only the transportation itself but also the urban structure like people’s dwelling, working, shopping behaviours and so on because people consider and decide all of these things comprehensively (Polzin, 1999; Rhee, 2011; Yu et al., 2010). Steven and Polzin (1999) noted that transportation investment affects land-use considerably, in terms of improvements in accessibility. Anas and Xu (1999) said that a congestion toll as a Pigouvian tax disperses enterprises around the suburbs, and increases urban productivity and efficiency.
Levying congestion taxes and subsidizing public urban transportations are often referred to traffic reducing policies although they have different purposes originally. Former’s is internalizing the external effects of car driving and latter’s is helping people to use buses or subways cheaply. It is true that both of them affect urban traffics, but interestingly, effects on urban structure are different because of their purposes and mechanisms
