72858 - Transport Planning M

Scheda insegnamento

Academic Year 2017/2018

Learning outcomes

The course of Transport Planning M has the objective of providing the principal scientific fundamentals for the simulation of transportation systems: in particular, the course provides the fundamental tools for the quantitative evaluation of impacts perceived by the users in relation to alternative projects of transportation system.

Course contents

Requirements/Prior knowledge

A prior knowledge and understanding of basic topics of the engineering of transportation system is required to attend with profit this course. In addition, students should master the Tecnica ed Economia dei Trasporti T.

Fluent spoken and written Italian is a necessary pre-requisite: all lectures and tutorials, and all study material will be in Italian.

Teaching methods

The course will include lectures and exercises.

Assessment methods

Achievements will be assessed by the means of a final exam. This is based on an analytical assessment of the "expected learning outcomes" described above. In order to properly assess such achievement the examination is oral with discussion of the project.

Higher grades will be awarded to students who demonstrate an organic understanding of the subject, a high ability for critical application, and a clear and concise presentation of the contents. To obtain a passing grade, students are required to at least demonstrate a knowledge of the key concepts of the subject, some ability for critical application, and a comprehensible use of technical language. A failing grade will be awarded if the student shows knowledge gaps in key-concepts of the subject, inappropriate use of language, and/or logic failures in the analysis of the subject.

Teaching tools

The slides that are shown in class are made available to students through the link AMS Campus. Software for the project and lecture notes are made available to students too.
