    • A system for navigation along a desired route on a desired future date may include a map interface operable to display a traffic condition and a travel time received via a communication network, and an automobile navigation network communicatively coupled to the communication network. The automobile navigation network may estimate the traffic condition and the travel time for travel along the desired route on the desired future date based on historical travel information, current traffic information and current weather information. Information regarding the estimated travel conditions may be automatically communicated to the map interface. The traffic condition may include geographic location information and/or route information. The historical travel information may include historical traffic information.
    • 用于沿期望的未来日期沿期望的路线导航的系统可以包括可操作以显示经由通信网络接收到的交通状况和行进时间的地图界面以及通信地耦合到通信网络的汽车导航网络。 汽车导航网络可以基于历史旅行信息,当前交通信息和当前天气信息来估计在期望的未来日期沿所需路线行驶的交通状况和行驶时间。 关于估计行驶条件的信息可以自动地传送到地图界面。 交通状况可以包括地理位置信息和/或路线信息。 历史旅行信息可以包括历史交通信息。

    • A map data distribution server that is connected to a network and distributes map data via the network is provided. The map data distribution server holds first map data and second map data that is of a newer version than the first map data and holds a plurality of update data including an instruction to update the first map data for each of partitions of a given size on a map. The map data distribution server decides whether a predetermined condition is fulfilled upon receiving an update request to update the first map data in a first partition out of the partitions to the second map data from a terminal communicating with the map data distribution server via the network, selects one of the plurality of update data relevant to the first partition, based on the result of the decision, and transmits the selected update data to the terminal.
    • 提供了连接到网络并通过网络分发地图数据的地图数据分发服务器。 地图数据分发服务器保存比第一地图数据更新的第一地图数据和第二地图数据,并且保存多个更新数据,该更新数据包括用于在给定尺寸的每个分区上更新第一地图数据的指令 地图。 地图数据分发服务器在从通过网络与地图数据分发服务器进行通信的终端接收到更新请求时,决定是否满足更新请求,将更新分区中的第一分区中的第一地图数据更新为第二地图数据, 基于决定的结果,选择与第一分区相关的多个更新数据中的一个,并将所选择的更新数据发送到终端。
