Abstract: A malfunction management unit includes an input/output module communicatively coupled to a controller. The input/output module is configured to monitor a sequence of intersection phases determined by the controller. A yellow trap detection module communicatively coupled to the input/output module is configured to determine whether a yellow trap sequence has occurred within the sequence of intersection phases. The yellow trap sequence may comprise a first state followed by a second state, the first state corresponding to permissive left turns in both a first direction and a second, opposing direction, and the second state corresponding to a protected left turn in the first direction.
