A transmitter for transmitting information about passengers waiting to board(22) wirelessly transmits information about passengers waiting to board to an electric train approaching to a platform. A controller(21) generates information about passengers waiting to board based on a sensing result. The controller transmits the information about passengers waiting to board to the electric train.
