图 1为本发明实施例提供的一种电子地图的交通路线确定装置的示 意图。 该装置 100可以实现本发明实施例提供的方法和装置。 如图 1所 示, 该装置 100包括一个或者多个处理器 151和非易失性计算机可读存 储器 152。 其中, 存储器 152中存储有操作系统 131和应用程序 132, 例如用于实现本发明实施例提供的方法的电子地图交通路线确定应用。
该装置 100可以是提供电子地图服务的服务器。 此时, 用户通过终 端设备将需要查询的路线的起点和终点信息提供给服务器。 服务器根据 起点信息和终点信息进行计算, 得出路线信息之后返回给用户的终端设 备进行显示。在一个实施例中, 用户可以将搜索公交 /地铁路线的起终 点信息提交至后台服务器。后台服务器通过计算得出从起点到终点的 公交 /地铁路线信息, 然后后台服务器通过得出的从起点到终点的公 交 /地铁路线信息, 再进行步行 /地铁路线的计算, 分别计算步行到公 交 /地铁站、 步行到换乘站、 从公交 /地铁下车后步行到目的地的详情 步行信息, 最后, 后台服务器将公交 /地铁路线信息和详情步行信息 进行整合, 并返回终端, 终端再将整合信息展示给用户。
所述装置 100还可以是用户设备。 此时, 存储器 152中的应用程序 132根据用户输入的起点和终点信息进行计算, 并将计算得到的路线信 息显示给用户。
在本发明实施例中,将步行路线结果整合到公交 /地铁等乘车路线结 果中予以展示,可以为用户提供展示如何步行到公交 /地铁站等乘车路线 的开始点、如何步行到换乘站等乘车路线的驻留点, 以及从公交 /地铁站 等下车后如何步行到目的地, 为用户提供了详细丰富的步行路线指示信 息, 从而提高了电子地图交通路线的匹配成功率。
图 2为本发明实施例的电子地图的交通路线确定方法流程图。
如图 2所示, 该方法包括:
步骤 201 : 确定路线起点和路线终点。
通过卫星定位系统, 例如美国的全球定位系统(GPS )、 中国的北斗 定位系统、 俄罗斯的格洛纳斯定位系统、 欧洲的伽利略定位系统, 或者 无线通信网络定位、 蓝牙定位等多种方式可以将真实道路网络的物理坐 标数据信息化, 以构成电子地图道路网络。 在这里, 首先在电子地图中 设置路线起点和路线终点。
在本发明实施例中, 可以通过在电子地图中直接点击的方式选择路 线起点和路线终点, 还可以通过输入地理位置名称来设置路线起点和路 线终点, 等等。
电子地图道路网络中包含有真实道路网络的地理坐标数据信息, 称 为电子地图路网数据。 在电子地图的路网数据中描述了每个路段的坐标 序列以及不同路段之间的连接关系。 在设置好路线起点和路线终点之 后, 需要将路线起点和路线终点分别吸附到电子地图道路网络中, 即将 路线起点和路线终点分别同电子地图道路网络中的具体坐标地理数据 确立对应关系。 具体吸附过程可以包括: 在确定路线起点和路线终点在 电子地图中的显示位置坐标数据之后; 再基于路线起点和路线终点在电 子地图中的显示位置坐标数据, 分别确定路线起点和路线终点在电子地 图道路网络中的地理坐标数据。
在本发明实施例中, 完成将路线起点和路线终点吸附到电子地图道 路网络之后, 在后续步骤中即可应用路线起点和路线终点的具体地理坐 标数据来计算路线起点和路线终点之间的分段乘车路线以及距离值。
步骤 202: 在电子地图道路网络中计算所述路线起点和路线终点之 间的分段乘车路线, 并在每一段分段乘车路线中设置有标识信息。
在这里, 可以基于路线起点与路线终点的坐标, 基于测距算法计算 离值。 分段乘车路线可以为多段, 具体含义是指除了步行之外乘坐公共 交通工具的路线。 现在常见的公共交通工具有: 出租车(Taxi )、 公交车 ( Bus )、 地铁(Subway )、 轻轨( Light rail)、 摩托车 (motorcycle ), 民 用航空飞行器, 等等。
在这里, 可以采用最短路径算法, 在电子地图道路网络中计算路 线起点和路线终点之间的上车点兴趣点 (POI ) 和下车点兴趣点; 再 根据计算出的上车点兴趣点和下车点兴趣点,确定路线起点和路线终 点之间的分段乘车路线。
在确定出分段乘车路线 (包括公交 /地铁线路信息) 之后, 可以 将信息结果以预先设置的数据结构进行存储, 例如通过链表存储, 存 储结构可以包括路线起点的 POI 点, 第一段乘车线路的上车站 POI 点, 第一段乘车线路的下车站 POI点, 直到第 N段乘车线路的上车 站 POI点以及第 N段乘车线路的下车站 POI点以及路线起点的 POI 点。
在电子地图中计算两点之间的乘车路线以及距离有多种算法, 通常 采用"最短路径算法"来计算路线。目前最常用的最短路径算法有: dijkstra 算法、 A*算法、 SPFA算法、 Bellman-Ford算法和 Floyd- Warshall算法, 等等。
例如, 本发明实施例具体可以采用 dijkstra算法求解。 dijkstra算法 是典型最短路算法, 用于计算一个节点到其他节点的最短路径, 主要特 点是以起始点为中心向外层扩展, 直到扩展到终点为止。 dijkstra算法能 得出最短路径的最优解。
以上虽然具体罗列了一些路径算法, 本领域技术人员可以意识到, 这种路径算法罗列仅是示范性的, 并不用于限定本发明实施例的保护范 围。
在某些情形下, 用户可能在行走中途需要驻留, 因此在步骤 201中 优选进一步设置驻留点, 而且将驻留点吸附到电子地图道路网络中, 即 将驻留点与电子地图道路网络中的具体坐标确立对应关系。 此时, 步骤 202具体可以包括: 在电子地图道路网络中计算从路线起点到驻留点的 乘车路线, 并且计算从驻留点到路线终点之间的乘车路线。
如果用户需要更改驻留点, 可以直接通过拖拽的方式在电子地图的 行走路线上更新驻留点, 然后将该更新驻留点再吸附到电子地图道路网 络中。
此时, 步骤 202具体可以包括: 在电子地图中展示从路线起点经过 该更新后驻留点后, 再到达路线终点的乘车路线以及距离值。
在一个实施例中, 驻留点的数目可以有多个, 此时可以按照用户预 先设置的驻留点先后顺序计算乘车路线以及距离值。 具体地, 亦可以采 用上述"最短路径算法"来计算得到驻留点间乘车路线以及距离值。
类似于驻留点的更改方式, 也可以直接通过拖拽的方式在电子地图 的行走路线上更改路线起点和 /或路线终点。 具体地, 在电子地图的乘车 路线上更改路线起点和 /或路线终点之后,需要将更新后的路线起点和路 线终点再吸附到电子地图道路网络中, 并且继续应用测距算法计算更新 后的乘车路线以及距离值。
在本发明实施例中, 在每一段分段乘车路线中设置有标识信息, 该 标识信息用于对每一段分段乘车路线进行标识。 比如, 可以将从路线起 点开始后的第一段分段乘车路线标识为 1、 将从路线起点开始后的第 2 段分段乘车路线标识为 2, 依次将从路线起点开始后的第 N段分段乘车 路线标识为 N,等等。 通过对每一段分段乘车路线进行标识, 可以便于识 别出各个分段乘车路线之间的分段步行路线, 从而能够将分段乘车路线 与分段步行路线按照正确的顺序, 组合为完整的交通路线。
步骤 203: 在电子地图道路网络中计算所述分段乘车路线之间的分 段步行路线, 根据所述标识信息将分段步行路线与分段乘车路线组合为 交通路线, 并显示所述交通路线。
计算出分段乘车路线之后, 还需要计算分段乘车路线之间的分段步 行路线(包括从路线起点到第一个乘车路线上车点的路线, 以及最后一 个个乘车路线下车点到路线终点之间的路线)。
在这里, 可以根据路线起点和路线终点以及分段乘车路线, 确定 出开始步行兴趣点和停止步行兴趣点;根据开始步行兴趣点和停止步 行兴趣点,采用最短路径算法确定所述分段乘车路线之间的分段步行 路线。 比如, 可以首先计算从路线起点到第一段乘车线路的上车站的 POI点步行信息;再计算从第一段乘车线路下车站到第 N段乘车线路 上车站 POI点的步行信息; 依次直到从第 N段乘车线路下车站到终 点 POI点的步行信息。
针对分段步行路线的计算,可以首先初始化每段步行路线的起终 点, 并初始化转弯节点的邻接矩阵, 初始化存储出行路径查找过程。 然后判断起、终点是否有效,即判断其是否在已有线路点的数据库中。 如果有效, 则起点置为首结点, 利用邻接矩阵查找各个转弯节点, 并 顺序链接; 再依次查找链中的节点的所有转弯节点数据, 并判断转弯 节点的特性; 最后查找链中的所有结点, 并按双亲结点逆序遍历至到 终点为止, 输出起点至终点的步行路径。
在一个实施例中, 可以根据分段乘车路线的标识信息, 确定出与 每个分段乘车路线相对应的分段步行路线;再将每段乘车路线以及与 其对应的分段步行路线相整合, 从而形成交通路线。
例如, 从路线起点开始后的第一段分段乘车路线标识为 1 , 则与 该路线标识相关的分段步行路线为: 从路线起点开始到第一段分段乘 车路线的上车点之间的行走路线;从路线起点开始后的第 2段分段乘 车路线标识为 2, 则与该路线标识相关的分段步行路线为从第一段分 段乘车路线的下车点开始到第二段分段乘车路线的上车点之间的行 走路线; 等等。
从数据合并的角度看, 分段乘车路线与分段步行路线的组合过程 可以包括: 首先从分段乘车路线中遍历取出分段的数据; 再遍历判断 当前段数据是否为从起点到第一段上车站、 第一段下车站到第 N 段 上车站或第 N段下车站到终点的线路信息, 如果是, 则根据每段的 标识信息, 在分段步行路线数据中找出相应段的步行线路信息; 再将 相应段的步行线路信息, 放置分段乘车路线信息相应段的数据后, 并 使用相应段的位置标识, 组成新的数据结构; 再将新的包含有分段乘 车路线与分段步行路线的数据, 返回给终端; 从而终端根据该数据结 构, 在显示分段乘车路线信息的基础上, 进行筒要显示或详细显示分 段步行路线。 当页面的显示空间有限时, 可以使用筒要显示方式, 即仅 在页面上显示筒要信息, 当用户需要查看详细的内容时, 通过操作来将 筒要信息展开, 从而显示全部的详细内容。 查看之后, 用户还可以将显 示的详细内容折叠起来, 以便节省显示空间。 例如, 用户可以通过鼠标 的点击操作来展开或者收缩折叠的部分。
在一个实施例中, 显示交通路线包括: 筒要显示所述交通路线中的 分段步行路线, 或者详细显示所述交通路线中的分段步行路线; 或筒要 显示所述交通路线中的分段乘车路线, 或者详细显示所述交通路线中的 分段乘车路线。
计算完路线起点与路线终点之间的交通路线以及该交通路线的距离 值之后, 可以通过多种方式在电子地图中展示交通路线以及该交通路线 的距离值。 比如, 可以通过高亮的方式显示交通路线, 或者在提示框中 显示该交通路线的距离值。
图 3为本发明实施例的一种电子地图的交通路线显示示意图。
由图 3 可见, 在本发明实施例中, 在电子地图中增加步行到公交 / 地铁站、 步行到换乘站、从公交 /地铁下车后步行到目的地等三段详细信 息 (如图 3中步行信息 1、 2、 3所示)。
在图 3中, 步行信息 1和 2包含更多详细信息, 使用筒要显示方式 以便节省占用的页面空间, 用右侧的下拉箭头 "V" 表示。 用户点击下 拉箭头之后, 可以展开显示更多的详细内容。 如图 3所示, 步行详细信 息 11和 12为步行信息 1的详细信息; 步行详细信息 21和 22为步行信 息 2的详细信息。 步行信息 3不包含详情, 因此右侧没有下拉箭头。 用 户点击步行信息 3可以直接进入地图。
图 4为本发明实施例的另一种电子地图的交通路线显示示意图。 在 图 4中, 增加了一个用于显示步行详情的按钮 401。 用户可以通过步行 详情按钮 401—键展开或者收起所有步行详情。 本发明实施例还提出了一种电子地图的交通路线确定装置。
