Advanced Driver Assistance Systems (ADAS) are today becoming increasingly common in the market. The safety potential of these systems has been evaluated using different approaches in several studies. In order to quantify the effects of ADAS on accidents described by insurers` claim files, German Insurers Accident Research has performed a comprehensive study. The database used for the study was a representative excerpt from the German Insurers' data, covering 2,025 accidents. Statistical methods were used to extrapolate these accidents up to 167,699 claims.

The conclusions of the analyses are as follows:​ a Collision Mitigation Braking System (CMBS) which is able to gather information from the environment, to warn the driver and to perform a partial braking maneuver autonomously (CMBS 2), could prevent up to 17.8 % of all car accidents with personal injuries in the data sample. The theoretical safety potential of a Lateral Guidance System, consisting of Lane Change Assist and Lane Keeping Assist, was determined to be up to 7.3 %.

Hence, a car fleet equipped with CMBS 2 and Lateral Guidance could avoid up to 25.1 % of all car accidents in the data sample. This theoretical safety potential is based on the assumptions that 100 % of the car fleet is equipped with these systems and the driver reacts perfectly when warned.
