Purpose SPIs

The purpose of SPI is:

  • to reflect the current safety conditions of a road traffic system (i.e. they are considered not necessarily in the context of a specific safety measure, but in the context of specific safety problems or safety gaps)
  • to measure the influence of various safety interventions, but not the stage or level of application of particular measures
  • to compare between different road traffic systems (e.g. countries, regions)
