A system comprising: a memory including data regarding a geographical extent of a registered geographical area stored thereon, the data indicating a geographical extent of discrete cells of the registered geographical area, the data further indicating a geographical extent of a restricted area within the geographical area that a vehicle is prohibited from entering, the data further indicating a geographical extent of an extended restricted area within the geographical area that fully surrounds the restricted area, and the data further indicating a polygonal area within the geographical area that fully surrounds the extended restricted area; position determination circuitry to determine a position of the vehicle in the registered geographical area; and conflict detection circuitry to: determine, based on the position, to which cell of the discrete cells the position corresponds; determine if the determined cell includes at least a portion of the polygonal area therein; in response to a determination that the position is situated within the polygonal area, determine whether the position is situated within the extended restricted area; and in response to a determination that the position is situated within the extended restricted area, provide one or more signals to transceiver circuitry of the conflict detection circuitry to cause the transceiver circuitry to transmit an alert to the vehicle indicating that a conflict exists; wherein the extended restricted area includes the restricted area extended in all directions a distance that is greater than, or equal to, a maximum width or a maximum length of all vehicles in the geographical area plus an error in the position weighted by a safety factor. a memory including data regarding a geographical extent of a registered geographical area stored thereon, the data indicating a geographical extent of discrete cells of the registered geographical area, the data further indicating a geographical extent of a restricted area within the geographical area that a vehicle is prohibited from entering, the data further indicating a geographical extent of an extended restricted area within the geographical area that fully surrounds the restricted area, and the data further indicating a polygonal area within the geographical area that fully surrounds the extended restricted area; position determination circuitry to determine a position of the vehicle in the registered geographical area; and conflict detection circuitry to: determine, based on the position, to which cell of the discrete cells the position corresponds; determine if the determined cell includes at least a portion of the polygonal area therein; in response to a determination that the position is situated within the polygonal area, determine whether the position is situated within the extended restricted area; and in response to a determination that the position is situated within the extended restricted area, provide one or more signals to transceiver circuitry of the conflict detection circuitry to cause the transceiver circuitry to transmit an alert to the vehicle indicating that a conflict exists; wherein the extended restricted area includes the restricted area extended in all directions a distance that is greater than, or equal to, a maximum width or a maximum length of all vehicles in the geographical area plus an error in the position weighted by a safety factor. determine, based on the position, to which cell of the discrete cells the position corresponds; determine if the determined cell includes at least a portion of the polygonal area therein; in response to a determination that the position is situated within the polygonal area, determine whether the position is situated within the extended restricted area; and in response to a determination that the position is situated within the extended restricted area, provide one or more signals to transceiver circuitry of the conflict detection circuitry to cause the transceiver circuitry to transmit an alert to the vehicle indicating that a conflict exists; wherein the extended restricted area includes the restricted area extended in all directions a distance that is greater than, or equal to, a maximum width or a maximum length of all vehicles in the geographical area plus an error in the position weighted by a safety factor.
