The course aims to provide each student with the ability both to recognize the technical characteristics of any transportation infrastructure, and to identify the theoretical framework for an evaluation of their performance. Topics will be introduced in such a way as to nurture the strong analytical skills which students will find useful for solving problems of a professional dimension. The cultural approach of the course will form the basis of knowledge useful for understanding all practical applications of the Construction of Road, Railways and Airports course from the 1st year of the Master level, and for addressing issues arising in the advanced specialization courses from the 2nd year of the Master course belonging to the Infrastructure and Transport Systems (Pavement and Track Analysis and Design, Design of Transportation Infrastructures). In particular, the student will acquire the following skills: - ability to analyze the transport demand at the design stage of the infrastructure and its components from functional and structural points of view; - ability to assess the interaction between drivers, vehicles, road and environment (pilot, aircraft, runway and environment in the case of airports) for the purposes of geometric design; - ability to assess the pavement performance in terms of stress-strain response under the repeated action of moving loads (vehicles and aircraft); - ability to identify the physical and mechanical properties of construction pavement and subgrade materials. In the final examination the student needs to: - know the relationship and interactions between the components of transportation infrastructures; - be familiar with the reference models and analysis methods specific to each type of infrastructure; - apply these models to the geometric, functional and structural design of transportation infrastructures. For the purposes of their judgment skills and ability to relate to other professionals, the student has to: - know how to write short reports in the form of exercises; - justify any design choices; - identify the orders of magnitude of numerical values that characterize the variables; - represent the designed elements in graph form; - use the specific terminology correctly.

The student is required to know the basic disciplines of civil engineering, with particular emphasis on Topography, the Science and Technology of Materials and Structural Mechanics. An understanding of written and spoken English is also required.

1. General characteristics of Transportation Infrastructures (TI) (5%); 2. Organization of TI networks, demand for mobility, analysis of TI in terms of capacity and quality of service (10%); 3. Driver-vehicle-road-environment interaction modes (pilot-aircraft-runway-environment for the airport environment) (20%); 4. Fundamentals of geometric design (35%); 5. Fundamentals of pavement structural analysis (10%); 6. Physical-mechanical properties and constitutive models of materials for infrastructure (20%). An equal distribution of time between roads, railways and airports will be observed for all the topics.

For each lesson topic there is a corresponding number of practical lessons with the objective of learning calculation methods. The exercises are organized on two levels: - combined teams, in which exercises will be presented and solved by the tutor; - separate teams (two teams in total), in which exercises will be presented and solved by the students with the assistance of a tutor. Each student is required to keep a book of exercises, containing the texts of the different exercises and their corresponding solutions. The book of exercises will be assessed during the final examination. Outside of the official timetable, students will be assisted by teaching assistants. The text of exercises is provided by the tutors. Each student needs to have a pocket calculator and basic drawing tools. There is the possibility that in the preparation of the final drawings the students will use specific software (CAD), also available at the University Computer Facilities (LAIB). Normally, to facilitate completion of the assigned task, it is expected that each hour of exercise in the classroom be matched by an additional hour of the students personal time.

Exam: Written test; Compulsory oral exam; Individual essay;

The first part of the final examination is written and lasts 2 hours without the aid of notes or books. The written test consists of 2 questions (theoretical questions and exercises). Students are required to include theory implications and their applications. The solutions of exercises need to be correct in terms of procedure and numerical results. The second part of the final examination consists of the oral exam. Only students who have passed the written test are admitted to the oral exam, which consists of: - a discussion on the written test; - verification of the book of exercises (the student must produce this during the oral exam); - oral examination with the lecturer to assess the ability of the student to synthesize the knowledge gained through the formulation of at least one question.

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.
