    • Disclosed is a traffic information distribution apparatus 1 including date-time information in traffic information acquired by the traffic information acquire unit 12 or generated by the traffic information prediction unit, and accumulates the traffic information in the traffic information DB 13. When the traffic information distribution apparatus 1 receives distribution request information transmitted from the in-vehicle terminal 5, based on date-time information of reference traffic information held by the in-vehicle terminal 5 included in the distribution request information, the traffic information distribution apparatus 1 retrieves traffic information including the same date-time information as the date-time information of the reference traffic information from the traffic information DB 13. Then, difference traffic information generation unit 18 generates difference traffic information between the retrieved traffic information and traffic information to be distributed, and the traffic information distribution apparatus 1 distributes the generated difference traffic information to the in-vehicle terminal 5.
    • 公开了一种交通信息分发装置1,其包括由交通信息获取单元12获取或由交通信息预测单元生成的交通信息中的日期时间信息,并且将交通信息累积在交通信息DB13中。 当交通信息分配装置1接收到从车载终端5发送的分发请求信息时,根据包含在分发请求信息中的车载终端5所保持的参考交通信息的日期时间信息,交通信息分配装置 1从交通信息DB13检索包括与参考交通信息的日期时间信息相同的日期时间信息的交通信息。 然后,差分交通信息生成部18生成检索到的交通信息和要分发的交通信息之间的差分交通信息,交通信息分配装置1将生成的差分交通信息分配给车内终端5。
