Road Traffic Collisions 2010-2020

I am keen to see the information relating to the geographical location of serious road traffic collisions in three Council areas (or across NI if this breakdown is not available). Please provide a breakdown of every road traffic collision where there has been either serious injury or a fatality across the Lisburn and Castlereagh / Ards and North Down and Newry Mourne and Down Council areas over the last 10 years with the specific geographical location of each accident identified by both grid reference (if available) and full address. Please provide the data on an excel sheet. If it difficult to provide this data by Council area, then the information for all of Northern Ireland with post code break-down will be fine.
