Abstract
A blocked rail crossing detection and notification system is described. The system includes a processing device, a communications interface communicatively coupled to the processing device and operable for facilitating communications between the processing device and at least one external device, and at least one vehicle detection mechanism placed proximate to a rail grade crossing. The at least one vehicle detection mechanism is communicatively coupled to the processing device and operable to provide signals to the processing device indicative of the presence or non-presence of a vehicle within a defined area surrounding an intersection of a roadway and one or more railroad tracks. The processing device is further programmed to communicate the presence or non-presence of a vehicle along with supporting correlative visual data within the defined area to the at least one external device via the communications interface.
