The course deals with the geometric and functional design (or re-design in the case of rehabilitation) of transportation infrastructures. The topics are introduced in such a way as to promote in each student the capacity to independently analyze problems from a professional point of view. Throughout the course, there will be opportunities to update students on the progress of scientific research in this specific field. In particular, the student will acquire the following skills: - ability to produce geometric drawings of infrastructures and their components, - ability to assess operational functionality and safety; - ability to estimate construction costs. For the final exams, the student needs to know: - the interactions between the various components of transportation infrastructures, - the models and methods useful for geometric and functional design; - the rules, regulations & standards currently in force. For their judgment skills and ability to relate to other professionals, students have to be able to: - compile technical and descriptive reports, - adopt and motivate design choices, - draw tables of the project, - coordinate design groups; - communicate and engage with specialists from other civil engineering disciplines (structures, geotechnics, hydraulics, topography), - use the terminology specific to sector appropriately.

Students are required to have fundamentals of Transportation Infrastructures from undergraduate programs, and to attend the Construction of Roads, Railways and Airports course (at the graduate level). An understanding of written and spoken English is also mandatory.

1. Introduction to transportation infrastructures in the world (5%) 2. Aspects in common in the design of transportation infrastructures (35%) - Computer-aided design - Terrain model formation - Horizontal and vertical alignment - Transition curves - Design levels - Quantity computation and cost estimation 3. Roads (30%) - Principles and application of functional design - Geometric design rules - Horizontal/vertical coordination - Safety and consistency analysis - Roadside hazards and protection - Intersections and interchanges 4. Railways (15%) - Technical characteristics of railways - Vehicle/railway interaction - Design principles of existing and planned lines - Track layout, switches and crossings 5. Airports (15%) - Airport organization - Aircraft performance - Aircraft/runway interaction - Runway design - Taxiway design

Video projector for slides during lectures and tutorials. No consumables. Lecture notes, handouts of the slides used in class, texts of design themes assigned and technical standards will be made available on the course webpage. Students will receive print credits for the printing of the project.

With the sole exception of the introductory part of the course, there is a corresponding number of hours of exercise which serve to help students learn about computational and design methods and tools. A road project is assigned to distinct groups composed of no more than four students. It will include: - a technical and descriptive report (including operational analysis, speed profiles, sight analysis, geometric assessment, design of safety barriers, and cost estimation); - plans and longitudinal profiles, - cross sections (typological and for computation purposes). As a tutorial, exercises on the operational analysis and design of roads will be presented and solved, to support students in the project development. The project is checked at least three times during the course. It is expected to be delivered to the teacher within the week following the end of the course. The electronic copy of the project must be in a pdf format. The delivery must be processed via POLITOApp. Material for the project is provided on the website page of the course. Specific software for the design of infrastructure facilities will be available (OpenRoad ConceptStation and OpenRoad Designer from Bentley). It will be presented in the class and used by students as a design tool. As a rule, the group must include a self-completed work to complete each assignment. The lecturer and the instructor will provide continuous assistance in the lab and with tutoring meetings. Lectures: 40 hrs. Practice and tutorials: 20 hrs. (in the first two months) Tutoring (optional): 3 hrs. per group Seminars (optional): 6 hrs.

Profillidis, V.A., Railway Management and Engineering, Ashgate ed. Horonjeff, R., McKelvey, F.X., Planning and Design of Airports, McGraw Hill. The following will be made available on the course webpage: - Teaching material (slides) presented during the lectures, - Exercise texts, - Design manuals, - Technical standards.

Exam: Compulsory oral exam;

It is expected that an individual oral exam, lasting 45 minutes, will be held. To be admitted to the oral exam it is necessary to obtain a positive result in the exercises. The oral exam consists of: - a discussion of the exercises, - an interview involving the formulation of at least three questions. The examination has the objective to assess if the student has acquired sufficient autonomy and ability to understand and solve the proposed design problem, in compliance with mandatory and non-mandatory design rules.

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.
