Outline of Final Research Achievements

The railway network in Tokyo metropolitan area has been developed to reduce both train congestion and impedance of transfers through providing high frequency train operations. However, small irregularities in services are resulting in significant delays in the railway service, as the railway system is currently operating very close to its capacity.
This study focuses on train operation to recover knock-on delay under high-frequency intervals and elucidate recovery mechanism. The study simulates train operations which are not only radial line but also loop line. Finally, the countermeasures against the delay are illustrated based on the results of the train operation simulation analysis.
