    Abstract: An unmanned aerial vehicle (UAV) system for maintaining roadway personnel safety includes a monitoring device configured to be worn by a user and to provide a notification, a UAV including a sensor configured to sense a signal indicating a railway condition and/or a railway event, and a ground station configured to house the UAV when the UAV is not in use. The ground station is further configured to be mounted on a train or vehicle. The system further includes a processor and a memory that contains instructions, which, when executed by the processor, cause the system to selectively deploy the UAV from the ground station when the ground station is supported on the train or the vehicle, receive the signal from the sensor, detect the railway condition and/or the railway event based on the received signal, and transmit the notification to the monitoring device based on the based on the sensed signal.

    Abstract: An unmanned aerial vehicle system includes a ground station, a tether assembly coupled to the ground station, and an unmanned aerial vehicle. The unmanned aerial vehicle having a quick release mechanism selectively coupled to the tether assembly to restrain movement of the unmanned aerial vehicle. The quick release mechanism is electrically actuatable to decouple the tether assembly from the unmanned aerial vehicle for enabling the unmanned aerial vehicle to fly freely.

    Abstract: A landing station for an unmanned aerial vehicle includes a landing surface and a centering wheel. The centering wheel is coupled to the landing surface and has a spoke extending therefrom. The spoke is positioned to rotate relative to the landing surface in response to rotation of the centering wheel relative to the landing surface. The spoke is configured to rotate into engagement with a landing leg of the unmanned aerial vehicle to impart centrifugal force onto the landing leg sufficient to rotate the unmanned aerial vehicle toward a predetermined position on the landing surface.
