Outline of Final Research Achievements

There are several urban rail lines of high congestion rate in Tokyo. Train delays have occurred due to high congestion rate and the huge number of passengers. It is necessary to increase the railway capacity. However, it is difficult to improve capacity due to the reduction of the subsidy budget. In Japan, the minimum operation interval is 120 seconds, but overseas a large number of railways are operated 90 seconds. We can reduce congestion of 180% to 140% by improving operation system.
The possibility of high frequency operation system that can reduce the investment amount was analyzed by agent simulation model and theoretical based on the operation curve diagram. As a result, it was found that the operation interval can be reduced by the moving block signaling system than the current on the Denentoshi and Hanzomon line. In addition, it showed that by increasing the truck capacity of Shibuya station, possible to achieve operation interval of approximately 90 seconds.
