A system wirelessly receives identification of a reportable navigation event from one or more vehicles, the identification including vehicle location information. The system determines a locality to which the reportable event applies. The system determines one or more television broadcast stations predefined as having a broadcast area that covers the locality. Additionally, the system defines navigation data for vehicle navigation systems to address the event and deliver the navigation data to the determined television stations, along with broadcast instructions for the television stations to broadcast the navigation data via Advanced Television System Committee (ATSC) technology.
