Abstract
Systems, methods, and other embodiments described herein relate to improving the communication of a railroad crossing warning. In one embodiment, a method includes identifying a railroad crossing in a path of a road user. The method further includes in response to determining that a train is approaching the road user at the railroad crossing, determining whether a warning mechanism of the railroad crossing satisfies a crossing threshold that is based, at least in part, on a safety condition of the warning mechanism. Moreover, the method includes controlling a display of the road user to output a virtual railroad crossing bar on the display according to the safety condition responsive to determining that the warning mechanism satisfies the crossing threshold.
