Control apparatus for monitoring a traffic section, comprising a sensor means that senses the traffic section, a receiving means that wirelessly receives traffic participant data from traffic participants, wherein the traffic participant data of a respective traffic participant comprises position data of the respective traffic participant and information associated with the position data regarding a traffic participant type of the respective traffic participant, a merging means that merges the position data of the respective traffic participant and sense information of the sensor means into fusion data of the respective traffic participant, and a determination means that determines whether there is an anomaly in a presence pattern of a traffic participant of a predetermined traffic participant type in the traffic section based on the fusion data of the respective traffic participants and the information regarding the traffic participant type of the respective traffic participants, wherein the traffic section is a traffic signal controlled road intersection region, characterized in that an anomaly exists in a presence pattern of a traffic participant of a predetermined traffic participant type in the traffic section if an autonomous motor vehicle, an automated motor vehicle, or an electrically or partially electrically driven motor vehicle is present within a base region of the road intersection region after a predetermined clearance time has elapsed, and by a triggering means that triggers a predetermined signaling if there is an anomaly in a presence pattern of a traffic participant of a predetermined traffic participant type in the traffic section. a sensor means that senses the traffic section, a receiving means that wirelessly receives traffic participant data from traffic participants, wherein the traffic participant data of a respective traffic participant comprises position data of the respective traffic participant and information associated with the position data regarding a traffic participant type of the respective traffic participant, a merging means that merges the position data of the respective traffic participant and sense information of the sensor means into fusion data of the respective traffic participant, and a determination means that determines whether there is an anomaly in a presence pattern of a traffic participant of a predetermined traffic participant type in the traffic section based on the fusion data of the respective traffic participants and the information regarding the traffic participant type of the respective traffic participants, wherein the traffic section is a traffic signal controlled road intersection region, characterized in that an anomaly exists in a presence pattern of a traffic participant of a predetermined traffic participant type in the traffic section if an autonomous motor vehicle, an automated motor vehicle, or an electrically or partially electrically driven motor vehicle is present within a base region of the road intersection region after a predetermined clearance time has elapsed, and by a triggering means that triggers a predetermined signaling if there is an anomaly in a presence pattern of a traffic participant of a predetermined traffic participant type in the traffic section.
