This data flow is sent from the Manage Emergency Services function to the Manage Maintenance and Construction function to report the operational status (state of the sensor device, configuration, and fault data) of security sensors, including threat sensors (e.g., thermal, acoustic, radiological, chemical), intrusion and motion detection sensors, object detection sensors, and infrastructure integrity sensors. These sensors are located in secure areas frequented by travelers (i.e., transit stops, rest areas, park and ride lots, modal interchange facilities, on-board a transit vehicle, etc.) or areas typically away from travelers, such as bridges, tunnels, roadway infrastructure, etc. By monitoring this data flow, the receiving process can monitor the health and current status of field equipment, and arrange for repair if deemed necessary. It consists of the following data items each of which is defined in its own DDE:

+ traveler_object_detection_sensor_status
+ traveler_intrusion_motion_sensor_status
+ threat_sensor_status
+ object_detection_sensor_status
+ intrusion_motion_sensor_status
+ infrastructure_integrity_sensor_status
+ vehicle_threat_sensor_status
+ vehicle_object_detection_sensor_status
