    • A method for transmitting data to a traffic information server includes obtaining, at a mobile vehicle, data including at least one of a vehicle speed and a vehicle location at a then-current time, and determining whether the data is redundant. Determining whether the data is redundant may be accomplished by at least one of comparing the data with other data previously transmitted to the traffic information server from an other mobile vehicle or determining whether the data falls within an expected range for a predetermined time interval. The method further includes transmitting the data, via a wireless communication system, to the traffic information server from the mobile vehicle if the data is determined to be non-redundant. Also disclosed herein is a system to perform the method.
    • 将数据发送到交通信息服务器的方法包括:在移动车辆处获取当前时刻包括车速和车辆位置中的至少一个的数据,以及确定所述数据是否是冗余的。 确定数据是否冗余可以通过将数据与先前从其他移动车辆发送到交通信息服务器的其他数据进行比较或者确定数据是否在预定时间间隔内处于预期范围内的至少一个来实现。 该方法还包括:如果数据被确定为非冗余,则经由无线通信系统将数据从移动车辆发送到交通信息服务器。 本文还公开了执行该方法的系统。

    • The described principles provide a method and system for identifying a potentially closed road based on reroute requests, and of accommodating the potential road closure while continuing to test the road status periodically via routing decisions and rerouting requests. While the optimal route assumes that the potentially closed road is open, a replacement route is defined assuming that the potentially closed road is closed. A fraction of users are sent along the optimal route, and if a reroute request is received, the potentially closed road is assumed to be closed still. The affected user is rerouted to a recovery route that matches the optimal route up to the potentially closed road, and then differs from the optimal route thereafter to avoid the potentially closed road.
    • 所描述的原理提供了一种用于基于重新路由请求识别潜在封闭道路的方法和系统,并且通过路由决定和重新路由请求周期性地继续测试道路状态来容纳潜在的道路封闭。 虽然最佳路线假定可能封闭的道路是敞开的,但假设可能封闭的道路关闭,则定义替换路线。 按照最佳路线发送一小部分用户,如果收到重新路由请求,则假设潜在的封闭道路静止。 受影响的用户被重新路由到与最佳路由匹配的恢复路由,直到潜在的封闭道路,然后与最佳路由不同,以避免潜在的封闭道路。
