AbstractDimensioning of public transport long distance, regional and urban services. Specification and quantification of the ressources needed, such as rolling stock and staff. Introduction to different forms of traction, energy supply and running time calculation. Capacity calculation of railway lines and nodes. Capacity allocation and optimization.
ObjectiveStudents will develop a knowledge on all resources, as well on train side as on infrastructure side, needed to produce market-oriented public passenger transport services. They will get a general understanding on the trade off between the different ressources involved and they will be able to make use of the dedicated methodes of resource dimensioning. They will learn the basic principles of the technologies of the traction technology.
