Abstract: A system for alerting a user in a safety zone adjacent a stationary vehicle includes one or more sensors configured to generate a sensor signal in response to a detected location and/or trajectory of a moving vehicle in an encroachment zone and/or the safety zone. The encroachment zone is a region adjacent the safety zone in which vehicles are at risk of entering the safety zone. A control unit is configured to receive the signal from the one or more sensors and to determine, responsive to the sensor signals, a likelihood of the moving vehicle entering the safety zone. The control unit is further configured to generate a trigger signal if the likelihood of the moving vehicle entering the safety zone is greater than a predetermined threshold. An alarm unit is configured to receive the trigger signal from the control unit and to automatically trigger an alarm protocol when the trigger signal is received to alert the user in the safety zone.
