A safety system, and associated methods of operation, for detecting a mobile hazard on a pathway and reporting to a user information relating to the object to help the user avoid a collision with the mobile hazard. The safety system includes a sensor system for detecting the concurrent presence of both a user and a mobile hazard within a monitoring zone of the sensor system. Upon detection of both the user and the mobile hazard within the monitoring zone, the sensor system generates a sensor signal. The sensor signal is received by a reporting system, which in response, generates a warning signal to alert the user to the presence of the mobile hazard.
