    • A traffic information aggregating apparatus (hereinafter an aggregating apparatus) receives traffic information from a network apparatus. The aggregating apparatus generates aggregated data in which the traffic information for each previously determined aggregation time is aggregated, and stores the aggregated data into an aggregated data management table correspondingly to an aggregation identifier. The aggregating apparatus determines, at the interval of the aggregation time, whether a difference between the aggregated data and a base value is within a previously determined range, and accumulates, in the case where it is within the range, the aggregated data to corresponding accumulated data of the aggregated data management table, and resets the aggregated data. In the case where it exceeds the range, the aggregating apparatus exports the aggregated data and/or the accumulated data of the aggregated data management table to the monitor server.
    • 交通信息聚合装置(以下称聚合装置)从网络装置接收交通信息。 聚合装置生成聚合数据,其中针对每个先前确定的聚合时间的交通信息进行聚合,并将聚合数据与聚合标识符相对应地存储到聚合数据管理表中。 聚合装置以聚合时间的间隔确定聚合数据和基准值之间的差是否在预先确定的范围内,并且在其范围内的情况下,将聚合数据累加到相应的累加 聚合数据管理表的数据,并重置聚合数据。 在超过该范围的情况下,聚合装置将聚合数据管理表的汇总数据和/或累计数据输出到监视服务器。
