MAIDS is the most comprehensive in-depth data currently available for Powered Two-Wheelers (PTWs) accidents in Europe. The investigation was conducted during 3 years on 921 accidents from 5 countries using the OECD common research methodology.
ACEM, the European Association of Motorcycle Manufacturers, lead the MAIDS study supported by a group of 9 partners. MAIDS was co-funded by the European Commission.
Within five European countries, five areas were identified due to their representativity of the PTW accident patterns. Each sampling area was handled by a team appointed by the MAIDS management group. A total of 921 accidents cases were investigated, each using a questionnaire with 2000 variables. The aggregate database that was so generated forms the basis for the MAIDS report.
