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.
