ECONOMIC EFFECT OF ITS IMPROVEMENT IN JAPAN

This study aims to systematically evaluate the effects of deploying ITS in Japan. These effects are broadly classified into flow effects and stock effects. The former is determined by the investment on the ITS-related facilities, while the latter vary largely according to the contents and the saturation level of ITS services. Therefore effective ITS deployment scenarios for the first step were considered. Next, by using a multi-sector general equilibrium model based on macroscopic industrial relation table, flow effects of the ITS investment on the scenarios were evaluated through measurement of inducing effects on demand and employment. Stock effects measured were improvement of productivity due to the improvement of efficiency in transportation and reduction of CO2 caused by the change of industrial structure.
