Outline of Final Research Achievements

Ultra-high-frequency operation is essential to the realization of UCRT (Ultra-Convenient Rail Transport). In this research based on the railway signalling system called "Pure Moving Block (PMB)", which is expected to be the most widely adopted one in the near future, it was shown that there could be many methods of ultra-high frequency train scheduling and its management. For example, the current route switching methods in railways (ground-side switching) are known to be the obstacle in shortening the minimum headways (time interval between trains), and this research have found a method to virtually avoid this obstacle.
Also in this research, comparison of various railway signalling systems, including the existing systems and some theoretically proposed systems, in terms of minimum headways and other evaluation criteria, have been performed to provide basic data to help the realisation of future ultra-high frequency train operation.

Academic Significance and Societal Importance of the Research Achievements

本研究で前提とした「純移動閉塞（PMB）」を含む鉄道信号システムについては多くの検討成果があるが，超高頻度化に向けて様々な手法の開発余地があること，すなわち従来と同等の安全性を維持しつつ列車運行頻度を向上する余地が残っていることが示された。列車運行頻度向上の社会的ニーズが大きいことは論を待たないので，この研究成果の社会的意義もまた大きいと考えられる。また，様々な鉄道信号システムと超高頻度化の関係について定量的かつ体系的な比較が行われたので，その結果は列車運行頻度向上に関する基礎的な知識ベースとなることが期待される。
