The aim of this paper is to analyze and to improve the current planning process of the passenger railway service. At first, the state-of-the-art in research is presented. Given the recent changes in legislature allowing competitors to enter the railway industry in Europe, also known as liberalization of railways, the current way of planning does not reflect the situation anymore. The original p...

The maintenance of railway track is highly relevant for the service quality and safety. This task demands huge technical and human resources. Therefore an optimal deployment of the available resources is crusial for the cost-effectiveness of railway operation. Furthermore, the track geometry maintenance activities need to be planned up to two years in advance. For this reason the French railway...

Decision Support and Consensus Building for PLANiTS Developments in intelligent transportation systems simultaneously Present challenges and opportunities to urban transportation planning. The challenges to planning stem from the increased range and added complexity of the choices available to transportation planners. The implementation of IWS technologies, many of which have system-wide implic...

In this paper we describe the successful application of a sophisticated Operations Research model and the corresponding solution techniques for scheduling the 6,500+ drivers and conductors of the Dutch railway operator NS Reizigers (Netherlands Railways). In 2001 the drivers and conductors were very dissatisfied with the structure of their duties, which led to nation wide strikes. However, the ...

This perspective explores how transportation decision-making can better support public health objectives, including reduced crashes and pollution emissions and increased physical activity. Conventional transportation planning tends to overlook negative health impacts resulting from increased motor vehicle travel and potential health benefits from shifts to alternative modes. Raising the priorit...

Özet When compared with the other transportation systems, railway systems are economical, safer and more environment friendly. Despite all these features, investments on railways in Turkey remained quite restricted in comparison to other European countries. The initial construction costs of railways are high and developing its signaling system also requires a lot of attention. Signaling system ...

This paper explores quantitative evaluation criteria for service and potentials of new service from the transportation viewpoint. For this purpose, we analyze transport networks of railway, subway, and waterbus, and have revealed the following implications: (1) efficiency criterion proposed by Latora [7, 8] and centrality criterion in the complex network literature can be applied as quantitativ...

We review two papers that are of historical interest for combinatorial optimization: an article of A.N. Tolstŏı from 1930, in which the transportation problem is studied, and a negative cycle criterion is developed and applied to solve a (for that time) large-scale (10×68) transportation problem to optimality; and an, until recently secret, RAND report of T. E. Harris and F. S. Ross from 1955, ...

This paper proposes a framework for using business and organizational scenario-planning techniques for regional strategic transportation-planning purposes. The paper provides a brief history of scenario planning as it emerged from business-strategic planning activities and gives an overview of its goals and limitations. The paper then reviews the context for scenario planning in regional transp...

1 Chinese railway system serves as an important role for the economy of China and the travel needs 2 of its citizens. As China is subject to frequent earthquake events, it is important to investigate 3 how to strengthen the railway system to retain its service after earthquakes. This paper proposes a 4 comprehensive methodology to suggest the optimal investment plan using historical earthquake ...
