    • Traffic information, including flow information and incident information, obtained through a traffic management system for providing and facilitating the exchange of traffic information between a remote location and a vehicle may be used in route calculation by a navigation device. The navigation device may recalculate a route based on anticipated user error. Alternatively, the navigation device may recalculate a route using received traffic information triggered by the receipt of a traffic information update, or triggered by the passage of an amount of time. The broadcast rate of traffic information updates may vary temporally (providing more frequent updates during peak commute times) or geographically (providing more frequent updates to metropolitan areas with increased traffic information needs). If route calculation is triggered by an elapsed amount of time, the amount of time may vary to be shorter during peak commute times. Additional route calculation techniques allow the incorporation of historical traffic information or the use of the most recent traffic information if incomplete traffic information is available. Still further route calculation techniques may calculate a best route by avoiding zigzagging or evaluating an assigned cost of a potential route.
    • 通过导航装置的路线计算,可以使用通过交通管理系统获得的用于提供和促进远程位置与车辆之间的交通信息交换的交通信息,事件信息。 导航装置可以基于预期的用户错误重新计算路线。 或者,导航装置可以使用由接收到交通信息更新触发的接收到的交通信息重新计算路线,或者通过一段时间的时间来触发。 交通信息更新的广播速率可以在时间上变化(在高峰通勤时间期间提供更频繁的更新)或地理上(在具有增加的交通信息需求的大城市地区提供更频繁的更新)。 如果路线计算由经过的时间量触发,则在通勤时间峰值时间可能会变短。 如果不完整的交通信息可用,额外的路线计算技术允许并入历史交通信息或使用最近的交通信息。 进一步的路线计算技术可以通过避免锯齿形或评估潜在路线的分配成本来计算最佳路线。

    • Traffic information, including traffic flow information and traffic incident information, obtained through a traffic management system for providing and facilitating the exchange of traffic information between a remote location and a vehicle may be presented to a user on a user display in the vehicle. In one embodiment, the navigation system automatically filters traffic information that is located farther than a predetermined distance from the vehicle. In another embodiment, the navigation system filters traffic information that is not located within the same time zone as the vehicle. The user may also enter user preferences manually through a menu provided by the vehicle radio. In other words, the traffic information may be presented to the user in several circumstances, either as cued by the user, or automatically presented by the traffic management system.
    • 通过用于提供和促进远程位置与车辆之间的交通信息交换的交通管理系统获得的交通信息,包括交通流量信息和交通事故信息可以在车辆中的用户显示器上呈现给用户。 在一个实施例中,导航系统自动地过滤距车辆预定距离更远的交通信息。 在另一个实施例中,导航系统过滤不在与车辆相同时区内的交通信息。 用户还可以通过车载无线电提供的菜单来手动输入用户偏好。 换句话说,交通信息可以在多种情况下被呈现给用户,无论是由用户提示还是由交通管理系统自动呈现。
