In a mobile system and a mobile management system, when an emergency notification that an urgent car 3 is approaching is transmitted from a base station 5 to a general owner-driven car 1, the distance between the general owner-driven car 1 and the urgent car 3 is calculated on the basis of the current position of the general owner-driven car 1 and the current position of the urgent car 3 under the control of a CPU 11. If the distance is within a predetermined value, the base station notifies the driver of the general owner-driven car that the urgent car is approaching. |
