TRANSPORT MODELLING AND PLANNING

Course objectives

• Objectives of the course To provide a methodological background for the simulation and the design of transport systems, aimed at the evaluation of interventions on the infrastructure and service network, as well as at the application of polices for the mobility of people and goods. The subjects will be developed through phenomena analyses, model definitions, and algorithm applications to elementary cases. A synthesis of the arguments presented in the course is listed below: system approach and transport supply – 1 credit random utility theory and passenger demand modelling – 3 credits advanced choice models and freight demand models – 1 credit network loading and assignment – 2 credits equilibrium models and od matrix estimation – 2 credits transit assignment – 1 credit dynamic traffic assignment and network design – 2 credits

Exam mode
The course is articulated in around 10 chapters and 60 sub-chapters. Two or three questions are made on different parts of the course with general scope reflecting the sub-chapters of the program. For each questions, depending on the answer, the theme is deeply analyzed with more specific questions, or we try to verify that the candidate has acquired at least the minimum knowledge on the proposed theme. Occasionally, if this does not emerge from the colloquium, we check the ability to cast the theoretical notions into practical application examples.
