    • 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。
