The goal of the course is to provide students with the methodological foundations of transport systems analysis, through the coverage of the most important theories that are at the basis of the transport economics, technique, planning and management, including energy and environmental aspects together with technologies for ITS (Intelligent Transport Systems). It can therefore be seen as a formative course to provide a general framework on transport systems, that are analysed through the explanation of their main technical characteristics, beyond considering the economic viewpoint. The structure of the course, that is multidisciplinary and transversal as regards different master degrees of this Politecnico, is an occasion for students to raise their awareness on the need of an integrated approach in order to develop truly operational skills in the transport domain. In parallel, the solution of practical exercises targets the development of planning skills of the students through the learning of the basic techniques that are needed to analyse transport systems.
The knowledge acquired all along the course is both methodological and applied. The methodological knowledge is based on learning about theories and methods to dimension a transport system (all the transport modes), both private and public, as well as to evaluate its economic efficiency, the environmental and energy impact, also under the point of view of the external costs. Furthermore, the study of the economic theories on which the markets are based allows understanding the principles of transport systems regulations (fare policies, internalisation of costs). The applied knowledge is acquired through the experimental work carried out during the course, which provides the analysis of real cases to which apply the learned theories. For example, the students learn how to evaluate the performances of the transport systems (daily capacity, carrying capacity, level of service), how to evaluate the economic benefits and costs, whether and when road transport of freight can be more convenient that rail-road combined transport and how to optimise freight or passenger transport among different origins and destinations. The knowledge acquired during the course allows to develop: a) the ability to describe and analyse a transport system; b) the mastery of the basic techniques to dimension a transport system; c) the ability to measure the performances of a transport service; d) the skills in the evaluation of a transport system according to the point of view of the different stakeholders (users, firm operating the service or managing the system, general public, policy and decision maker); e) the ability to analyse the markets and to define the fares of the different transport systems; f) the ability to organise an intermodal transport of goods and optimise the available resources, using modern technologies and ITS (Intelligent Transport Systems).
Basic notions of Mathematics, Statistics, Physics and Mechanics. Basic notions and methods on the evaluation of investment projects given in courses such as "Construction project management" (Civil Engineering) or "Business economics and organization" (Mechanical Engineering).

Technical visit: 4.5 hours Technical visit at transport facilities and terminals (railway terminals and/or intermodal terminals and/or metro and/or ports and/or transport and traffic control rooms and/or transport vehicle industries).
The course for the Mechanical Engineering class provides 6 credits. Thus, the students who choose such course will have a deduction of 20 hours, as detailed in the "course topics" field. This choice aims to maximise the student learning, taking into account his/her educational background and avoiding potential overlapping with previous courses.
Workshops, that last about three to four hours each, are targeted at the development of numerical applications that are related to the topics covered during lessons, in particular on the following points: Workshops, that last about three to four hours each, are targeted at the development of numerical applications that are related to the topics covered during lessons, in particular on the following points: 1. VEHICLE MOTION. The movement of single vehicles, active forces and resistances, especially in public transport systems. The motion equation. Computation of the performances of vehicles moving at constant speed or during acceleration and deceleration phases. 2. CAPACITY OF MOTORWAYS. Vehicular flows, levels of service and HCM manual. 3. CAPACITY OF RAILWAYS. UIC 406 R leaflet method. 4. RESOURCES FOR TRANSPORT SERVICES. Graphical timetables, fleet and crew scheduling. 5. FINANCIAL ANALYSIS.

The nature of the course and the available references do not allow to have only one textbook; thus, the attendance to the course is fundamental for an effective learning process. All along the course, proper textbooks will be suggested to complete the training process. Concerning specific topics, ad hoc material (articles, reports, etc.) will be uploaded on the course web page at Politecnico web site.
Lecture notes; Exercises;
Exam: Written test; Compulsory oral exam;
The exam implies a written as well as an oral part, both are compulsory. The goal of the exam is to ascertain the knowledge of the topics covered during classes and the achievement of the above mentioned learning outcomes. Written exam: solution of numerical exercises and quizzes on the topics dealt during the workshops. The written exam will include two exercises and some quizzes and it will last about 2.5 hours. It will be possible to consult personal notes only to solve the two exercises. Oral exam: it will deal with all the topics covered during the course and it will compulsorily take place after few days from the written exam. The oral exam will last about 30 minutes. The admittance requirement to the oral exam is having obtained a score of at least 18/30 in the written exam and, for each of the two exercises and for the quiz, a score of at least 5/10.
In addition to the message sent by the online system, students with disabilities or Specific Learning Disorders (SLD) are invited to directly inform the professor in charge of the course about the special arrangements for the exam that have been agreed with the Special Needs Unit. The professor has to be informed at least one week before the beginning of the examination session in order to provide students with the most suitable arrangements for each specific type of exam.
