Abstract: The disclosure relates to a method for detecting a need of assistance of a first road user (16). The method comprises receiving first image data (I1) comprising a representation of the first road user (16). Moreover, the method comprises determining whether the first road user (16) is involved in an accident based on the first image data (I1). The method also comprises receiving second image data (I2) comprising a representation of a second road user (18) and determining whether the second road user (18) is departing based on the received second image data (I2). It is inferred that the first road user (16) needs assistance if the first road user (16) is determined to be involved in an accident and if the second road user (18) is determined to be departing. Moreover, a data processing apparatus (24), a computer program (32), and a computer-readable storage medium (30) are shown. Also a use of the first road user characteristic (C1) is described.
