Abstract

A utterance type road traffic information providing system comprises a roadside apparatus (100) installed along a road where vehicles travel, in a parking lot, or near a parking lot and adapted for transmitting alarm information by wireless communication, a utterance type vehicle-mounted device (200) adapted for receiving the alarm information by wireless communication from the roadside apparatus (100) and outputting the alarm information and mounted in the vehicle, and a administration server (300) for communicating various information with the roadside apparatus (100). The utterance type vehicle-mounted device (200) has a predetermined operating unit and a control unit. The control unit provides again a utterance type output from the beginning by sound according to the alarm information supplied from the roadside apparatus (100) when a predetermined operation of the operating unit is made. By a simple method, the alarm information is again confirmed (re-outputted).
