Method and electronic control system for detecting adverse traffic conditions

The invention relates to a method (200) for determining an adverse traffic condition of a first road user (100) and a second road user (140), comprising the following steps: acquiring (202) position information for determining a position of the first road user and uncertainty information for determining a position detection uncertainty of the first road user (100); acquiring (204) position information for determining the position of the second road user and uncertainty information for determining the uncertainty of the position detection (150) of the second road user (140); converting (206) the uncertainty information of the first road user into a first covariance matrix dependent on the position of the first road user for describing a position-dependent presence probability (110) of the first road user; converting (206) the uncertainty information of the second road user into a second covariance matrix relating to the position of the second road user for describing a position-dependent presence probability (
