The data are sorted by year of registration (vetustà).The annual data files are issued thanks to an agreement between the Municipality of Bologna and the Automobile Club of Italy (ACI) and come from the database of the Public Automobile Register (PRA).The aforementioned agreement expired in 2018. The data of the following years are extracted from the opendata portal of the Emilia Romagna Region (see).With the new agreement with ACI, the extracted data have a different structure and refer only to vehicles.
