    • A traffic information processing apparatus for alleviating the problem of discrepancy between a plurality of traffic information which may be acquired from different sources is disclosed. In the case where a plurality of traffic information are acquired, the information are corrected into reference traffic information selected from the plurality of the traffic information. For example, the traffic information processing apparatus acquires first traffic information (VICS information) used for the navigation process and second traffic information (probe traffic information) having a different source from the first traffic information. From the first and second traffic information, the traffic information for a common object is extracted, and based on the difference between them, the correcting information used for correcting the second traffic information is generated. The traffic information on an object not contained in the first traffic information is acquired by correcting the second traffic information on the object using the correcting information.
    • 公开了一种用于减轻可能从不同来源获取的多个交通信息之间的差异问题的交通信息处理装置。 在获取多个交通信息的情况下,将信息修正为从多个交通信息中选择的参照交通信息。 例如,交通信息处理装置获取与导航处理有关的第一交通信息(VICS信息)和与第一交通信息不同的源的第二交通信息(探测交通信息)。 从第一和第二交通信息中,提取公共对象的交通信息,并且根据它们之间的差异,生成用于校正第二交通信息的校正信息。 通过使用校正信息来校正对象的第二交通信息来获取未包含在第一交通信息中的对象上的交通信息。

    • A traffic information system includes: a past information database for storing past information, which is colleted for road links in a predetermined area, of a past mobile object on a road; a current information database for storing running information, which is colleted for the road links in the predetermined area, of a current mobile object; link correlation analyzing means in which correlations of traffic information among each road link in the predetermined area are calculated from the past information stored in the past information database, and output as link correlation information among the road links; combination calculating means for calculating weighting information for obtaining the current information as a sum of the link correlation information; and traffic information estimating means for calculating estimated traffic information for a link where the current information is not collected based on the link correlation information and the weighting information.
    • 交通信息系统包括:过去的信息数据库,用于存储在道路上过去的移动物体在预定区域中收集道路连接的过去信息; 用于存储当前移动对象的用于在预定区域中为道路链路收集的运行信息的当前信息数据库; 链路相关分析装置,其中根据存储在过去信息数据库中的过去信息计算预定区域中的每个道路链路之间的交通信息的相关性,并作为路段链路之间的链接相关信息输出; 组合计算装置,用于计算用于获得当前信息的加权信息作为链接相关信息的和; 以及交通信息估计装置,用于基于所述链路相关信息和所述加权信息来计算未收集所述当前信息的链路的估计交通信息。
