PURPOSE:To enable cars to accurately understand their allocated destinations by providing a map display means to each car for radio reception of the plane coordinates of allocated destinations from an allocation center and confirming the allocated destination of each car via said map display means. CONSTITUTION:The data collected previously from each customer are converted into the plane coordinates and displayed on the map of a map book 1 with the telephone numbers used as key words. These plane coordinates are inputted to a computer C set at an allocation center Z together with the names of customers. When the family member X1 of a customer X calls the center Z to tell his/her name together with the telephone number, a receptionist Z1 sends the name X1 and high/her telephone number to an operator Z2. The operator Z2 inputs the telephone number to the computer C and finds out the coordinates 'KE-10' corresponding to the relevant destination to sends the coordinates 'KE-10' and the name X1 to a liaison man Z3. The liaison man Z3 sends by radio, etc. both the coordinates 'KE-10' and the name X1 to the driver M of a car Y. Then the driver M confirms the address of the customer X via a map display device.
