Road map - What information do I find in the police road crash registration (BRON)?

BRON contains the crashes that have been registered by the police and offers important information for road analyses. Often, nature and extent of the road safety problem are first determined on the basis of this register.


  • From late 2009 the number of registered crashes declined considerably due to changes that took place within the police force. Since 2013 the number of registered crashes has been increasing again as a result of including crashes that are registered with a characteristics+ mention. Therefore the fluctuations in the numbers after 2009 do not necessarily indicate road safety changes.
