The euroFOT project is the first large-scale Field Operational Test (FOT) of multiple Advanced Driver Assistance Systems (ADAS) in Europe. It will evaluate the impact of ADAS on safety, traffic efficiency, environment, driver behaviour and useracceptance in real life situations with normal drivers by means of collected data from instrumented vehicles. By offering valuable information for the short- and long-term impact of ADAS the euroFOT project aims to encourage the deployment of ADAS. Altogether, about 1000 vehicles equipped with different ADAS technologies will take part in the field operational test. The FOT is coordinated by five Vehicle Management Centers (VMC) and carried out at various operation sites across six European countries (France, Germany, Italy, Netherlands, Sweden and United Kingdom). Within this paper the approach and the requirements for implementing a reliable and automated incident detection process by means of CAN-data for assessing the impact of ADAS at the German1-VMC are presented.
