The present disclosure relates to a method for identifying scenarios of interest for development, verification and/or validation of an ADS of a vehicle. The method comprises obtaining a risk map of a surrounding environment of the vehicle, wherein the risk map is formed based on an actuation capability of the vehicle and a location of free-space areas in the surrounding environment. The actuation capability comprises an uncertainty estimation for the actuation capability and the location of free-space areas comprises an uncertainty estimation for the estimated location of free-space areas. The risk map comprises a risk parameter for each of a plurality of area segments comprised in the surrounding environment of the vehicle. Further, the method comprises determining a compounded risk value of the ADS based on the risk parameters of a set of area segments of the risk map. The method further comprises monitoring a scenario trigger by monitoring at least one of the determined compounded risk value against a compounded risk trigger threshold, a development of the risk map over time against a map volatility trigger threshold, and a development of the compounded risk value over time against a risk volatility threshold. Then, if the scenario trigger is detected, the method comprises storing sensor data from a plurality of sensors of the vehicle, the stored sensor data being from a time period around a point in time when the scenario trigger was detected.
