Abstract

A method performed by a database managing system for maintaining a database comprising reported traffic-affecting events is provided. The system derives a position of a first vehicle supporting detection of vehicle surroundings and determines by comparing the vehicle position to positions of reported traffic-affecting events comprised in the database, that the first vehicle is approaching at least a first traffic-affecting event. The system prompts the first vehicle to attempt to detect the first traffic-affecting event, which prompting comprises providing to the first vehicle an expected position of the first traffic-affecting event. The system receives a response from the first vehicle, which response indicates whether or not the expected position was at least partly unobstructedly observable by the first vehicle. The response further indicates—if the expected position was at least partly unobstructedly observable—whether or not the first traffic-affecting event was at least partly detected by the first vehicle.
