    • A CPU of a navigation device transmits probe information including link traveling information and average vehicle speed information at every predetermined time to an information distribution center. On the other hand, when receiving the probe information, a CPU of the information distribution center reads the road type corresponding to each link ID and user's average vehicle speed during uncongested road traveling from the probe information, and determines the vehicle speed region corresponding to this link ID from a vehicle speed region determination table. Thereafter, the CPU of the information distribution center creates traffic information from this vehicle speed region and the probe information, stores it in a center side traffic information DB and statistically processes traffic information of a certain period to generate a link cost corresponding to a link ID and a time zone of a relevant vehicle speed region of statistical traffic information.
    • 导航装置的CPU将每个预定时间的包括链接行进信息和平均车速信息的探测信息发送到信息分发中心。 另一方面,当接收到探测信息时,信息分配中心的CPU从探测信息中读取与非链接道路行驶中的每个链路ID和用户的平均车辆速度相对应的道路类型,并且确定与该探测信息对应的车速区域 来自车速区域确定表的链接ID。 此后,信息分发中心的CPU从该车速区域和探测信息创建交通信息,将其存储在中央侧交通信息DB中,并且统计处理一定时间段的交通信息,以生成与链路ID相对应的链路成本 以及统计交通信息的相关车速区域的时区。

    • When a link ID corresponding to a coordinate point sequence is stored in a matching table, devices, methods, and programs convert the coordinate point sequence into the link ID, but when the link ID is not stored in the matching table, the devices, methods, and programs extract one or more candidate links as candidates for the link corresponding to the coordinate point sequence based on the map information. When one candidate link has been extracted, the devices, methods, and programs convert the coordinate point sequence into the link ID of that extracted candidate link, and when a plurality of candidate links have been extracted, the devices, methods, and programs convert the coordinate point sequence into the link ID of one of the extracted candidate links based on the coordinate difference patterns corresponding to the link IDs within an area in the vicinity of the extracted candidate links.

    • A CPU specifies factors related to the month, the day of the week, and a time period including the current point in time, based on time data obtained by a timer. The CPU also specifies factors that are related to a grid ID and a road category of a given link, based on map display data, link data, and the like stored in an update map information database. The CPU then reads a sample collection number indicating the number of samples of probe information required to generate traffic information for that link and in sequence for other links. When a center traffic information DB contains stored therein, samples of probe information equal to or greater than the sample collection number for a link, the CPU generates the traffic information for that link and stores the generated traffic information as current traffic information.
    • 基于定时器获得的时间数据,CPU指定与月份,星期几和包括当前时间点的时间段有关的因素。 CPU还根据存储在更新地图信息数据库中的地图显示数据,链接数据等,指定与给定链接的网格ID和道路类别相关的因素。 然后,CPU读取指示为该链路生成交通信息所需的探测信息的样本数量以及其他链路的顺序的采样号。 当存储中心交通信息DB包含等于或大于链路的采样收集号的探测信息的样本时,CPU生成该链路的交通信息,并将生成的交通信息存储为当前交通信息。

    • There is provided an electromagnetic field intensity calculator for calculating the intensity of electromagnetic field radiated from an electric circuit device based on a moment method. A conductor pattern obtained from CAD data is divided into a square mesh pattern. In the mesh pattern of the outline part, the entire region in the mesh pattern is filled with the conductor pattern according to the ratio of area between the conductor pattern region and the blank region, or subjected to correction for blanking, so that a mesh data model is automatically configured by mesh pattern group consisting of only squares conforming to the moment method and reflecting the outline of the conductor pattern.

    • When a destination is set, a CPU transmits to an information distribution center average vehicle speed information and so on together with a request command requesting for statistical traffic information. On the other hand, a CPU selects statistical traffic information per vehicle speed region of a predetermined vehicle speed region for each secondary mesh to thereby search for a basic route to the destination. Subsequently, the CPU identifies a vehicle speed region for each road type from the average vehicle speed information and a vehicle speed region determination table, selects for each mesh ID of all the secondary meshes through which the basic route passes the statistical traffic information per vehicle speed region corresponding to the vehicle speed region identified for each road type from the statistical traffic information per vehicle speed region classified by road types, and distributes it to a navigation device.
