    摘要： A method is disclosed for determining a route taken by a user at a decision point in a navigable network in an area covered by an electronic map. The map comprises a plurality of segments representing navigable segments of the navigable network in the area covered by the electronic map. A user is travelling along a main route from an origin to a destination. An upcoming decision point is identified, and one or more alternative routes between the decision point and the destination generated. Data indicative of each route is stored in a route pool, associated with data indicative of the outgoing segment at the decision point that forms part of the route. Each route passes along a different outgoing segment, and which segments are all different to an outgoing segment included in a continuation of the main route. When the user has passed through the decision point, it is determined whether the current position of the user lies on the outgoing segment forming the continuation of the main route. If so, the main route continues to be used as the main route after passing through the decision point. If not, it is determined whether the current position is on an outgoing segment associated with one of the stored alternative routes. If so, then this alternative route is used as the new main route after the decision point. If not, a new alternative route from the decision point to the destination passing along the outgoing segment on which the current position is found is generated, and used as the new main route after passing the decision point.

    摘要翻译： 公开了一种用于确定用户在由电子地图覆盖的区域中的可导航网络中的决策点处采取的路线的方法。 该地图包括表示电子地图覆盖的区域中的可导航网络的可导航区段的多个分段。 用户沿着从起点到目的地的主要路线行进。 确定即将到来的决策点，并生成决策点与目的地之间的一条或多条备选路线。 指示每条路线的数据被存储在路线库中，该路线库与指示构成路线一部分的决策点处的出站路段的数据相关联。 每条路由通过一个不同的出站段，并且哪些段与包含在主路由延续中的出站段全部不同。 当用户通过决定点时，确定用户的当前位置是否位于构成主路线延续的出站段上。 如果是这样，主要路线继续作为通过决策点之后的主要路线。 如果不是，则确定当前位置是否在与所存储的替代路线之一相关联的输出段上。 如果是这样，那么这个替代路线被用作决策点之后的新的主要路线。 如果不是，则生成从决策点到目的地的新替代路线，该目的地经过在其上找到当前位置的离开段，并在通过决策点之后用作新的主要路线。

    摘要： A method is disclosed for determining a route taken by a user at a decision point in a navigable network in an area covered by an electronic map. The map comprises a plurality of segments representing navigable segments of the navigable network in the area covered by the electronic map. A user is travelling along a main route from an origin to a destination. An upcoming decision point is identified, and one or more alternative routes between the decision point and the destination generated. Data indicative of each route is stored in a route pool, associated with data indicative of the outgoing segment at the decision point that forms part of the route. Each route passes along a different outgoing segment, and which segments are all different to an outgoing segment included in a continuation of the main route. When the user has passed through the decision point, it is determined whether the current position of the user lies on the outgoing segment forming the continuation of the main route. If so, the main route continues to be used as the main route after passing through the decision point. If not, it is determined whether the current position is on an outgoing segment associated with one of the stored alternative routes. If so, then this alternative route is used as the new main route after the decision point. If not, a new alternative route from the decision point to the destination passing along the outgoing segment on which the current position is found is generated, and used as the new main route after passing the decision point.
