Joint local feature importance via LIME for each feature of the samples in the second scenario (SC2: night time vs. rush hour) for the joining methods JM1 (a), JM2 (b), and JM3 (c) compared to the BL (d). Each line connects the feature importance for one trip, and (a) the line width corresponds to the influence on the second level.
