In this paper, we present the application of a set of software engineering roles. Role definitions were developed using internationally recognized software engineering reference documents for a major railway development organization: Bombardier Transportation. The description of the Software Architect role is explained. This paper will also illustrate how the role set could be used for project-...

Transportation has historically had a major influence on cities their locations, growth and form. Civil engineers were the leading public servants in construction of railway and transit systems. With diversification of transportation and, particularly, growth of highways, the solutions to urban transportation have become extremely complex. Instead of only building new facilities, it is now nece...

INTRODUCTION TRANSPORTATION of people is increasing as our society grows and the demand for railway services that can provide high-speed and high-capacity transportation is becoming greater. The number of train rides taken in Japan in 2006 was 22,243 million, more than anywhere else in the world by some margin, making Japan one of the world’s leading railway nations. A major feature of railway ...

BACKGROUND Little is known about train suicide and factors influencing its prevalence. This study tests the hypotheses that railway density, railway transportation volume, familiarity with railway transportation and population density contribute to train suicide. It also tests the relationship between train suicide and general population suicide and examines the prevalence and the characteristi...

Safety is an essential requirement for railway transportation. There are many methods that have been developed to predict, prevent and mitigate accidents in this context. All of these methods have their own purpose and limitations. This paper presents a new useful analysis technique: timed fault tree analysis. This method extends traditional fault tree analysis with temporal events and fault ch...

This article gives an overview of the results of the author’s PhD thesis Schlechte [2012]. The thesis deals with the mathematical optimization for the efficient use of railway infrastructure. We address the optimal allocation of the available railway track capacity the track allocation problem. This track allocation problem is a major challenge for a railway company, independent of whether a fr...

As the second largest economic entity in the world, China plays an important role in controlling global carbon dioxide (CO2) emissions. The land transportation sector (including railway transportation and road transportation) has been the most important source of emissions in China and the average CO2 emissions of land transportation were 529.31 million tons during the period 2009e2012. In this...

The study of various countries rail transportation indicators is an appropriate criterion for evaluating the existing performance of Iranian railways. The experiences of other countries can be used to improve the efficiency of Iran’s rail transportation. At the beginning of the study, in order to compare the Iranian railway performance with railways of other countries, various efficiency indica...

Train path (infrastructure), rolling stock and crew scheduling are three critical planning decisions in railway transportation. These resources are usually planned separately in a sequential process that typically starts from planning (1) train paths and goes further on to (2) rolling stock and (3) train drivers. Such a sequential approach helps to handle the complexity of the planning process ...

The passenger line planning is a process of strategic long-term decision-making problem in the field of railway passenger planning. A line is a route between starting point and destination with certain stops, which has a certain frequency of train schedule. A new solution based on decomposition algorithm has been proposed in this paper, which is defined in a master problem and two sub problems....
