Post-evaluation of the Investment in Increasing Commuter Transport Capacity in Tokyo Metropolitan Area

Abstract

This study evaluates the effect of the past investment for commuter transport in Tokyo Metropolitan Area. The evaluation focuses on the track extension of five main trunk lines of the Japan National Railway. The user benefit and increase of profit (deficit) of the investment are estimated by the comparison of the actual situation (as“with”case) with the situation without the investment (as“without”case). The result shows that the user benefit and the increase of profit of the railway company by the investment are very large.
