    • In a case where a CPU 11 provided in an information distribution center 3 has received a request command for requesting predicted traffic information transmitted from a navigation apparatus 2 as well as vehicle information such as a navigator identifying ID, coordinate data of a vehicle position, or coordinate data of a destination, the CPU 11 searches a basic route based on update-purpose map information 14A, and sets a distribution range serving as a transmission target of traffic information 16A, 16B, and 16C. Then, the CPU 11 generates the predicted traffic information 16C such as congestion prediction information corresponding to the distribution range, extracts the predicted traffic information 16C of each link having a difference in the generated predicted traffic information 16C and the current traffic information 16A, and distributes the extracted predicted traffic information 16C to the navigation apparatus 2 together with a link ID of a corresponding link.
    • 在信息分配中心3中设置的CPU 11已经接收到用于请求从导航装置2发送的预测的交通信息的请求命令的情况下,以及诸如导航者识别ID,车辆位置的坐标数据或车辆位置的车辆信息 CPU 11基于更新目的地图信息14A搜索基本路线,并且设置用作交通信息16A,16B和16C的​​发送目标的分配范围。 然后,CPU 11生成与分配范围对应的诸如拥塞预测信息的预测交通信息16C,提取所生成的预测交通信息16C和当前交通信息16A之间的差异的各链路的预测交通信息16C, 将所提取的预测交通信息16C与对应链路的链路ID一起提供给导航装置2。

    • First, a determination is made as to whether or not an instruction to search for a route again has been issued. When it is determined that an instruction to search for the route again has been issued, a determination is made as to whether or not a destination arrival determination has been made. When a vehicle has reached an arrival road constituting a guidance route within a predetermined range from the destination, it is determined that the destination arrival determination has been made, and the guidance route is searched for again after increasing a road cost that takes into account an advancement direction in relation to the arrival road located in the vicinity of the destination of the set guidance route, whereupon the processing is terminated. As a result, the newly formed guidance route obtained as a result of the new search does not include at least a part of the road constituting the guidance route within the predetermined range from the destination, and therefore, a new guidance route according to which the destination can be reached along a different route to the previous route is obtained.
    • 首先,确定是否再次发出了搜索路线的指令。 当确定已经发出再次搜索路线的指令时,确定是否已经做出目的地到达确定。 当车辆到达构成从目的地的预定范围内的引导路线的到达道路时,确定已经进行了目的地到达判定,并且在增加考虑了目的地的道路成本之后再次搜索引导路线 相对于位于设定引导路线的目的地附近的到达道路的前进方向,结束处理。 结果,作为新的搜索结果而获得的新形成的引导路径不包括构成从目的地的预定范围内的引导路线的道路的至少一部分,因此,新的引导路径 目的地可以沿着与之前路线不同的路线达到。

    • A route guidance method provides route guidance from a current position to a destination by using a navigation apparatus capable of displaying a route from the current position to the destination in combination with a portable terminal carried by a user. The navigation apparatus produces a 2-dimensional code based on information associated with the destination and a location at which the user leaves his/her car en route to the destination and displays the thus produced code. The portable terminal acquires the information associated with the location at which the user leaves his/her car and the destination by reading the 2-dimensional code displayed by the navigation apparatus.
    • 路线引导方法通过使用能够与由用户携带的便携式终端组合地显示从当前位置到目的地的路线的导航装置,提供从当前位置到目的地的路线引导。 该导航装置基于与目的地相关联的信息和用户在途中离开他/她的汽车到达目的地的位置产生二维码,并且显示由此产生的码。 便携式终端通过读取由导航装置显示的二维码来获取与用户离开他/她的车和目的地的位置有关的信息。

    • Systems, methods, and programs, store map data including a roadway network, detect a current position of the vehicle, and detect or receive at lest one of a distance to another vehicle, a speed of another vehicle, and traffic congestion information. The systems, methods, and programs determine whether the vehicle is within a predetermined distance of a passing lane, a climbing lane, or a lane for slower traffic based on the detected current vehicle position and the map data. If the vehicle is within the predetermined distance, the systems, methods, and programs provide guidance regarding the passing lane, the climbing lane, or the lane for slower traffic based on at least one of the distance to the other vehicle, the speed of the other vehicle, and/or the received traffic congestion information.
