First Claim
1. An utterance type road traffic information providing device which receives alarm information from a roadside apparatus installed on or near a road with a vehicle traveling or a parking lot through wireless communication and which outputs the alarm information, the road traffic information providing device comprising:
- a communication unit configured to receive the alarm information from the roadside apparatus at timing at which a link is set up with the roadside apparatus;
a storage unit configured to temporarily store the alarm information;
an audio processing unit configured to convert the alarm information into audio information to output the audio information in utterance;
an operation unit configured to control the utterance output as needed; and
alarm information transfer unit configured to read out the alarm information stored in the storage unit according to a priority to transfer the alarm information to the audio processing unit when an operation of the operation unit is not performed and for transferring a received utterance output stop signal and the alarm information to the audio processing unit under a predetermined condition according to the operation content when the operation of the operation unit is performed,wherein when the utterance output stop signal is transferred by the alarm information transfer unit, an output is conducted in accordance with the priority of the alarm information or stored alarm information succeeding the alarm information whose utterance is intended to be stopped.

Abstract
An utterance type road traffic information providing device (system) provided with a roadside apparatus (100) set on a road where a vehicle travels, at a parking lot or a place adjacent to the parking lot for transmitting alarm information by wireless communication, an utterance type vehicle-mounted device (200) mounted on a vehicle for receiving the alarm information from the roadside apparatus by wireless communication and outputting the alarm information, a administration server (300) that exchanges various information with the roadside apparatus (100). The utterance type vehicle-mounted device (200) is comprised of a predetermined operation unit and a control unit. The control unit cancels a part or all of the utterance voice output of the alarm information supplied from the roadside apparatus (100) in accordance with a predetermined operation of the operation unit. An output of the same alarm information or alarm information irrelevant to its own vehicle is prevented.

6. A method for providing road traffic information for receiving, by a road traffic information providing device, alarm information from a roadside apparatus installed on or near a road with a vehicle traveling or a parking lot through wireless communication and of outputting the alarm information, the method comprising the steps of:
-
communicating to receive the alarm information from the roadside apparatus at timing at which a link is set up between the road traffic information providing device and the roadside apparatus; temporarily storing the alarm information; converting the alarm information into audio information to output the audio information in utterance; controlling the utterance output as needed; and transferring the alarm information by reading out the stored alarm information according to a priority of the alarm information to output the alarm information in utterance when an operation is not performed and outputting a received utterance output stop signal and the alarm information in utterance under a predetermined condition according to the operation content when the operation is performed, wherein when the utterance output stop signal is transferred in the alarm information transferring step, an output is conducted in accordance with the priority of the alarm information or stored alarm information succeeding the alarm information whose utterance is intended to be stopped.
