The invention provides an information transmission device and a traffic information distribution device which appropriately transmit information related to abnormal traffic states and prevent the amount of processed data from becoming too large. An information transmission device (1), which is mounted on a vehicle and transmits acquired information to a server S, is configured to be provided with: a communication unit (40) that communicates with the server; an abnormal state determination unit (10) that determines an abnormal state in which information needs to be transmitted; a primary information output unit (30) that transmits predetermined primary information from the communication unit to the server when it is determined that the state is abnormal; and a secondary information output unit (30) that transmits secondary information having a data capacity greater than that of the primary information to the server from the communication unit only when a secondary information request transmitted by the server in response to the transmission of the primary information is received.
本发明提供适当地传递与交通的异常状态相关的信息并且防止了处理的数据量变得过大的信息发送装置和交通信息分发装置。将搭载于车辆并将获取到的信息发送到服务器S的信息发送装置(1)构成为,具备:通信部(40),其与服务器进行通信;异常状态判别部(10),其判别需要发送信息的异常状态;一次信息输出部(30),其在判别为异常状态的情况下,从通信部向服务器发送预定的一次信息;以及二次信息输出部(30),其仅在接收到服务器响应于一次信息的发送而发送的二次信息请求的情况下,从通信部向所述服务器发送数据容量比一次信息的数据容量大的二次信息。
