This book contains a selection of the papers presented during the Scientific Seminar 2009 of the Italian Society of Transportation Scholars (SIDT) organized within the annual international conference of the Society, which took place in Milan.
The theme of the conference was "The effects of important events on land-use and transport" and it was stimulated by two forthcoming related events: the "Forum delle Culture", Naples, 2013 and notably the "Expo", Milan, 2015.
Selected paper focus on mathematical models and techniques for transport management and land-use effects in the presence of unusual demand, including some case studies.
This is the first book of SIDT proceedings produced in English in order to introduce SIDT activities to the international community.
Selected papers are a part of the research activities carried out by SIDT members, representing all the Italian university professors and researchers who study and teach topics in transportation, and contributing to the community debate on transport systems and related topics, such as land-use, economics, environment and energy in order to support worldwide efforts for a sustainable development.

Lorenzo Mussone is Associate Professor in Transportation and holds the courses of Transport Basics and Infomobility and Mobility Network Design at the Architecture and Society School, Department of Building Environment Science and Technology, of the Politecnico di Milano. His main research fields concern traffic models for control and evaluation of transport system performance.
Umberto Crisalli is Associate Professor in Transportation at the Department of Civil Engineering of "Tor Vergata" University of Rome. He teaches Traffic Flow Theory, Transportation System Theory and Transport Terminals.
