Abstract
By constructing traffic infrastructure like highway and high speed railway, much effect occurs, not only short terms follow effect but also various effects like increasing population, constructing office, in long terms near infrastructure areas. Especially, Shinkansenn (high speed railway in Japan) gives many effects and such effects our country's economic development. However current macro economic models cannot simulate effects each regional areas get. And simulate models for regional areas cannot simulate effects whole our country get. In this research, by improving previous macro economic simulation models we make the model system that can simulate the effect of constructing traffic infrastructure to national and regional areas. And by using this model, we check that we can use this model system for simulation by constructing traffic infrastructure.
