The aim of the course is to provide to the student operating capability to:

  • Analyse and show accident phenomena of a road transport system, identifying critical points
  • Understand principal accident causes through statistical analysis techniques and “in-depth” analysis
  • Identify most effective countermeasures for different cases, through correct use of tools for cost-benefit and cost-effectiveness analysis
  • Monitor the effects of interventions through correct application of results evaluation techniques

Syllabus outline

  • Description of road accident phenomenon: Phenomenon dimensions; indicators; characteristics in term of: transport modes, localization, users involved; comparison between Italian situation and other countries; current regulation background.
  • Accident data collection and management: accident data collection and management process in Italy; points of weakness of accident databases; innovative techniques for data collection and management through telematic tools; innovative databases: the European Road Safety Observatory.
