Railways, including local railways, serve as a form of public transport, and public transport is a constituent element of social infrastructure that helps support the lives of passengers. While it can be said that railways exist for the sake of their passengers, the converse is not true. Sound railway management cannot be readily sustained without a considerable number of passengers. With Japan now facing a downturn in total population, ensuring a sufficient pool of potential passengers within station territories has become a significant business challenge for local railway lines in particular. Ensuring sufficient populations within station territories is a nearly impossible task for a railway business, necessitating some form of outside assistance. Following the abolition of supply-demand adjustment regulations in 2000, recent years have seen an increasing number of local railway companies undergo transfers of management, making case studies on management revitalization of local railway companies of substantial social importance. This case study focuses on management revitalization of the Takamatsu-Kotohira Electric Railroad (Kotoden) in the Takamatsu urban area by employing the following analysis techniques: 1) Factor analysis of Kotoden’s successful management revitalization and comparisons with the findings of case studies on the Kishigawa Line 2) Detailed GIS (Geographic Information System) based analysis of changes in the populations of station territories along Kotoden lines 3) Analysis of the relationships between Kotoden’s successful management revitalization and urban planning 4) Comparative analysis with other urban areas The authors are convinced that the findings of this case study offer valuable information on successful management revitalization of local railways, given that success in this instance can be attributed to the fact that Kotoden’s management revitalization was authorized in recognition of its value as a public transport provider in the context of urban planning for the Takamatsu urban area. This case study was also able to show the utility and importance of analyzing population changes in station territories using GIS (100 m mesh population data). This research further demonstrated that tripartite management by local governments along the Kotoden railway lines, residents living along these lines (passengers), and the railway company itself are all major factors in the success of the management revitalization undertaken by this local railway company.JEL Classifications:O18, R14, R42

近年、北海道と本州間の鉄道輸送網において、事故・災害による不通が多発している。鉄道輸送網の不通は旅客だけではなく、物資輸送にも多大な影響を与えている。本研究は鉄道貨物輸送における代替経路探索モデルを構築し、津軽海峡線貨物列車脱線事故と有珠山噴火災害に適用したものである。本研究で構築したモデルは時刻を考慮しているため、便毎に経路を探索することができる。そのため、運行頻度や発着時刻等を含めた代替経路の評価が可能である。また、現実に採用されている列車待機を代替経路の一つとして、表現できる。モデルを事故・災害事例へと適用した結果、フェリー航路が代替輸送に有用であることが明らかにされた。すなわち、今後はフェリーも鉄道貨物輸送における代替経路として考慮すべきといえる。

On Japanese inter-regional railway, there are several networks. Shinkansen and existing lines (AC/DC/no electrification) have no inter-operability. We can regard that inter-operability is very important factor to evaluate quality or redundancy of inter-regional railway network.In this study, I analyzed concerning historical process of inter-operability in Japanese inter-regional railway network, and some example of making inter-operability and link stop with no alternative routes. Through this analysis, I can define current problems of inter-regional railway network in Japan.On ordinary condition, it is possible to increase social benefit by making inter-operability between Shinkansen to existing line. Yamagata Shinkansen project and Akita Shinkansen project are successful example.On situation of link stop, there are some risks to increase social losses. If that link has no alternative route, all trains cannot be operated. Even if that link has some alternative routes, many trains cannot be operated too. Because there are a large number of trains, slot of alternative route is not enough. 81days stop of San-yo Shinkansen is typical example there is no alternative routes.Those benefits or losses can be evaluated by quantitative method. But index of making inter-operability is next challenging.I trust that this study can provide some valuable knowledge to discuss development policy of inter-regional railway network, especially concerning making inter-operability between Shinkansen to existing line.

This paper deals with the effects of reduction of CO2 emission by a Modal Shift from road transport to railway as a result of Transportation Demand Management (TDM). In Toyota City, roads are seriously congested because of commuter traffic by private cars. Local governments, companies and people in and around Toyota City are concerned about TDM to improve the road conditions. Double tracking of the Aichi Loop Railway (from Mikawa-Toyota to Shin-Toyota; 3.6 km), an important option of TDM, has been completed. This project has increased transportation capacity, 4 shuttle trains per hour have been operating since March 15, 2008. It is expected that 4,000 commuting passengers will shift from road traffic to the railway. The Model Shift will reduce CO2 emissions from transportation by private cars at least 1,500 ton per year. This project has been succeeded, 1,000-2,850 number of commuter passengers have been modal-shifted from private car to railway.JFL Classification: Q51, R41
