图2是根据本申请一些实施例所示的一种与车辆相关联的数据处理方法的流程图。在本申请的一些实施例中,提供了一种与车辆相关联的数据处理方法,该方法可以由服务器110执行,所述方法200可以包括如下步骤:
S210:从与车辆相关联的终端设备获取行驶数据,所述行驶数据包括沿车辆路线的采样点的坐标。在一些实施例中,该步骤可以由系统400中的获取模块401执行。
在一些实施例中,所述终端设备可以是司机使用的终端,也可以是乘客使用的终端。例如,可以通过司机使用的终端,获取司机驾驶车辆产生的行驶数据。再例如,也可以通过乘客使用的终端,获取乘客乘坐车辆产生的行驶数据。在一些实施例中,所述行驶数据可以是车辆在行驶过程中产生的与车辆、道路、司机、乘客等相关的数据。所述行驶数据可以包括但不限于行驶路线信息、车辆位置信息、时间信息、速度信息、司机的基本信息、乘客的基本信息等。在一些实施例中,获取模块401可以在车辆的行驶路线上进行采样获取沿车辆路线的采样点。在一些实施例中,所述采样点可以视为车辆在行程中行驶路线上的轨迹点。需要注意的是,在一些实施例中,“采样点”和“轨迹点”可以互换使用。在一些实施例中,所述沿车辆路线的采样点中的每一个均对应于一个坐标,所述坐标可以是表示车辆在该采样点时的位置信息的位置坐标。例如,获取模块401可以获取每个采样点的经纬度表示,进而获得每个采样点的位置坐标。在一些实施例中,获取模块401获取的车辆的行驶数据还可以包括车辆经过每个采样点的时间信息和/或速度信息等。在一些实施例中,获取模块401还可以通过终端获取用户标识,并将用户标识作为终端上传的行驶数据的一部分进行存储。
S220:基于所述采样点的坐标,在至少一个行程数据集中记录所述行驶数据,其中,每个行程数据集对应一个行程标识。在一些实施例中,该步骤可以由系统400中的第一确定模块402执行。
在一些实施例中,所述行程数据集可以是记录车辆在一个行程中产生的行驶数据的数据集合。所述行程标识可以作为所述行程数据集中的数据来源行程的识别标记。在一些实施例中,所述行程数据集中记录的所述行驶数据可以包括对应行程的采样点及其坐标。
在一些实施例中,可以采用如下步骤在至少一个行程数据集中记录所述行驶数据:
(1)使用所述采样点的坐标,确定沿该路径的两个相邻采样点之间的距离变化范围;
(2)响应于确定两个相邻采样点之间的距离变化范围在预定阈值范围内,将所述两个相邻采样点中的第一采样点设置为行程的界限点;以及将所述第一采样点之前的行程上的采样点设置为第一行程集合,以及将所述第一采样点之后的行程上的采样点设置为第二行程集合,并为划分出的每个行程集合标记对应的行程标识。
在一些实施例中,所述距离变化范围可以是两个相邻采样点的距离与其前一个相邻采样点距离之间的变化范围,即某一个采样点至其前一个采样点的距离以及该采样点至其后一个采样点的距离的变化范围。在一些实施例中,当所述距离变化范围较小时,车辆可能处于送达乘客或等待乘客上车的状态,可以认为此时为一个行程的结束和/或新行程的开始。在一些实施例中,可以为所述距离变化范围设置一个预定阈值,用于确定其大小是否满足上述判断标准。在一些实施例中,当所述距离变化范围在预定阈值范围内时,即认为此时为上一行程的结束,此后的行程为新的行程。此时,可以将所述两个相邻采样点中的第一采样点设置为行程的界限点, 所述界限点之前的行程可以视为第一行程,将该行程上的采样点设置为第一行程集合;所述界限点之后的行程可以视为第二行程,将该行程上的采样点设置为第二行程集合。在一些实施例中,第一确定模块402可以为每个行程集合标记行程标识,例如,为第一行程集合标记第一行程标识,为第二行程集合标记第二行程标识。
示例性的,将本申请实施例应用于网约车场景中时,将网约车的一个订单可以视为一个行程。在乘客乘坐网约车开始一个行程时,由于网约车司机会停在上车点等待乘客上车,因此,在一定时间范围内相邻轨迹点之间的距离变化很小。鉴于上述特点,可以将获取的行程数据划分在不同的行程集合中。
一种可能的实施方式中,可以根据行驶数据中包括的每个轨迹点的位置坐标,确定相邻轨迹点之间的距离变化范围。这里,上述相邻轨迹点可以为时间上相邻的两个轨迹点,也可以为时间上依次相邻的多个轨迹点。
若确定的相邻轨迹点的距离变化范围在预设距离范围内,则以上述相邻轨迹点中任一个轨迹点为行程界限点,将该行程界限点之前的轨迹点对应的行驶数据划分在一个行程集合,将该行程界限点之后的轨迹点对应的行驶数据划分在另一个行程集合,并为划分出的每个行程集合标记对应的行程标识。
其中,上述相邻轨迹点中任一个轨迹点既可以作为一个行程的起点,也可以作为一个行程的终点。在具体实施过程中,可能存在无法判断上述行程界限点具体是一个行程的起点还是终点的情况,此时,可以将上述行程界限点同时作为上一个行程的终点和下一个行程的起点。
在一些实施例中,为了对指定空间范围的采样点数据进行灵活、快速的查询,还可以建立路段标识与行驶数据之间的匹配关系。在一些实施例中,建立路段标识与行驶数据之间的匹配关系可以包括以下步骤:
(1)基于所述沿车辆路线的采样点的坐标,确定与每个行程数据集匹配的路段标识。在一些实施例中,该步骤可以由系统400中的第二确定模块405执行。
(2)生成第二数据库,存储:与所述至少一个行程数据集匹配的行程标识;以及对应地,与行程标识匹配的路段标识。在一些实施例中,该步骤可以由系统400中的第二构建模块406执行。
在一种可能的实施方式中,可以根据每个终端上传的行驶数据中包括的每个轨迹点的位置坐标,确定每个轨迹点对应的路段标识。并且构建存储有每个行程集合的行程标识、与每个行程集合匹配的路段标识的第二数据库。
为了对指定空间范围的轨迹数据进行灵活、快速的查询,建立空间位置坐标与轨迹数据之间的匹配关系,在对城市交通数据进行分析的情况下,通常使用预先确定的路网来标识空间位置坐标。
结合城市交通道路情况,上述路网最基本的要素为路段(link)和节点(node)。其中,路段为两个节点之间的有向线段,是路网中最小的路程单位,每个路段对应一个路段标识。节点连接不同的路段,通常为路程的拐点、路口、停车场等位置。
由于使用路网标识空间位置坐标,需要将行驶数据中的每个轨迹点的位置坐标转换为路网中的空间位置坐标,通常情况下,行驶数据中每个轨迹点的位置坐标为通过定位技术获取的经纬度坐标,因此,在具体实施过程中,需要将行驶数据中的每个轨迹点的位置坐标转换为路段标识。具体的,可以采用如下步骤将行驶数据中的每个轨迹点的位置坐标转换为路段标识:
步骤1:获取每个路段标识包括的位置坐标范围;
步骤2:根据每个终端上传的行驶数据的每个轨迹点的位置坐标,确 定每个轨迹点落入的位置坐标范围;
步骤3:根据每个轨迹点落入的位置坐标范围,确定每个轨迹点对应的路段标识。
在构建了存储有每个行程集合的行程标识、与每个行程集合匹配的路段标识的第二数据库之后,后续可以支持基于路段标识来查询所需的行驶数据。
一种可能的实施方式中,在接收到请求端发送的携带有路段标识的查询请求时,可以从第二数据库中获取与路段标识匹配的第二行程标识。之后可以进一步从第一数据库中获取与第二行程标识匹配的行驶数据,并将获取的行驶数据发送给请求端。
在一些实施例中,为了对指定时间范围的采样点数据进行灵活、快速的查询,还可以建立时间标识与行驶数据之间的匹配关系。在一些实施例中,建立时间标识与行驶数据之间的匹配关系可以包括以下步骤:
(1)确定经过每个采样点的时间;以及响应于根据所述采样点的坐标记录所述至少一个行程数据集中的所述行驶数据,基于所述经过每个采样点的时间,确定与每个行程数据集匹配的时间标识。在一些实施例中,该步骤可以由系统400中的第三确定模块406执行。
(2)生成第三数据库,所述第三数据库存储所述行程标识,并相应地存储与所述至少一个行程数据集匹配的所述时间标识。在一些实施例中,该步骤可以由系统400中的第三构建模块407执行。
在另一种可能的实施方式中,根据每个行程集合中包括的经过每个轨迹点的时间,确定与每个行程集合匹配的时间标识;构建存储有每个行程集合的行程标识、与每个行程集合匹配的时间标识的第三数据库。
由于构建了存储有每个行程标识与每个行程标识匹配的时间标识的第三数据库,在接收到请求端发送的携带有时间标识的查询请求时,还可 以从第三数据库中获取与时间标识匹配的第三行程标识,然后从第一数据库中获取与第三行程标识对应的行驶数据,并将获取的行驶数据发送给请求端。
在对指定时间范围的轨迹数据进行查询时,如果上述指定时间范围很长的情况下,例如,需要获取半年乃至一年时间范围内的行驶数据,就会造成获取到的行驶数据的数据量过大,为后续分析带来很大的困难。因此,在上述指定时间范围很长的情况下,可以对获取的指定时间范围对应的行驶数据进行采样,并且可以根据具体获取的行驶数据的数据量设置对应的采样率,例如将采样率设置为0.1,就可以有效降低行驶数据的数据量。并且由于行驶数据的数据量本身就已经很大,设置合适的采样率对行驶数据进行采样,并不会明显降低分析结果的准确度,不会明显影响城市交通数据的分析效果。
S230:生成存储所述行程标识以及包括所述行驶数据的所述至少一个行程数据集的第一数据库。在一些实施例中,该步骤可以由系统400中的第一构建模块403执行。
在一些实施例中,所述第一数据库中可以记录有至少一个行程数据集的采样点及其坐标。在一些实施例中,第一构建模块403也可以构建第二数据库,所述第二数据库可以记录有至少一个行程数据集的采样点及其坐标,以及与所述至少一个行程数据集匹配的行程标识,以及对应地,与行程标识匹配的路段标识。在一些实施例中,第一构建模块403还可以构建第三数据库,所述第三数据库可以记录有至少一个行程数据集的采样点及其坐标,以及与所述至少一个行程数据集匹配的行程标识,以及与所述至少一个行程数据集匹配的时间标识。
S240:响应于从请求设备接收到包括第一行程标识的第一请求,从所述第一数据库获取由所述第一行程标识标记的第一行程数据集中的第一 行驶数据,并将所述第一行驶数据发送给所述请求设备。在一些实施例中,该步骤可以由系统400中的查询模块404执行。
在一些实施例中,所述请求设备可以是服务提供方使用的终端设备,也可以是服务请求方使用的终端设备。在一些实施例中,所述第一请求可以是请求设备的用户发出的查询请求,所述查询请求可以包括所述第一行程标识。在一些实施例中,查询模块404可以通过查询的方式从所述第一数据库获取由所述第一行程标识标记的第一行程数据集中的第一行驶数据。在一些实施例中,所述查询可以包括但不限于:基础查询、条件查询、分桶查询等。在一些实施例中,查询模块404还可以通过网络120将获取的所述第一行驶数据发送给所述请求设备。
在一些实施例中,查询模块404还可以响应于从所述请求设备接收到包括第一路段标识的第二请求,从所述第二数据库获取与第一路段标识匹配的第二行程标识;以及从所述第一数据库中获取与第二行程标识匹配的行驶数据,并将所述与第二行程标识匹配的行驶数据发送到所述请求设备。在一些实施例中,查询模块404可以通过网络120将获取的所述与第二行程标识匹配的行驶数据发送给所述请求设备。
在一些实施例中,查询模块404还可以响应于从所述请求设备接收包括第一时间标识的第三请求,从所述第三数据库中获取与所述第一时间标识匹配的第三行程标识;以及从所述第一数据库中获取与所述第三行程标识匹配的行驶数据,并将与所述第三行程标识匹配的行驶数据发送到所述请求设备。在一些实施例中,查询模块404可以通过网络120将获取的所述与第三行程标识匹配的行驶数据发送给所述请求设备。
本申请实施例中,通过构建存储有行程标识和与每个行程标识对应的行驶数据的第一数据库、存储有每个行程集合的行程标识、与每个行程集合匹配的路段标识的第二数据库和存储有每个行程集合的行程标识、与 每个行程集合匹配的时间标识的第三数据库,可以准确、快速、灵活地获取指定时间范围和空间范围的车辆数据。

需要说明的是,不同实施例可能产生的有益效果不同,在不同的实施例里,可能产生的有益效果可以是以上任意一种或几种的组合,也可以是其他任何可能获得的有益效果。
以上内容描述了本申请和/或一些其他的示例。根据上述内容,本申请还可以做出不同的变形。本申请披露的主题能够以不同的形式和例子所实现,并且本申请可以被应用于大量的应用程序中。后文权利要求中所要求保护的所有应用、修饰以及改变都属于本申请的范围。
同时,本申请使用了特定词语来描述本申请的实施例。如“一个实施例”、“一实施例”、和/或“一些实施例”意指与本申请至少一个实施例相关的某一特征、结构或特点。因此,应强调并注意的是,本说明书中在不同位置两次或多次提及的“一实施例”、或“一个实施例”、或“一替代性实施例”、或“另一实施例”或“另一个实施例”并不一定是指同一实施例。此外,本申请的一个或多个实施例中的某些特征、结构或特点可以进行适当的组合。
本领域技术人员能够理解,本申请所披露的内容可以出现多种变型和改进。例如,以上所描述的不同系统组件都是通过硬件设备所实现的,但是也可能只通过软件的解决方案得以实现。例如:在现有的服务器上安装系统。此外,这里所披露的位置信息的提供可能是通过一个固件、固件/软件的组合、固件/硬件的组合或硬件/固件/软件的组合得以实现。
所有软件或其中的一部分有时可能会通过网络进行通信,如互联网或其他通信网络。此类通信能够将软件从一个计算机设备或处理器加载到另一个。例如:从放射治疗系统的一个管理服务器或主机计算机加载至一个计算机环境的硬件平台,或其他实现系统的计算机环境,或与提供确定轮椅目标结构参数所需要的信息相关的类似功能的系统。因此,另一种能够传递软件元素的介质也可以被用作局部设备之间的物理连接,例如光波、电波、电磁波等,通过电缆、光缆或者空气实现传播。用来载波的物理介质如电缆、无线连接或光缆等类似设备,也可以被认为是承载软件的介质。在这里的用法除非限制了有形的“储存”介质,其他表示计算机或机器“可读介质”的术语都表示在处理器执行任何指令的过程中参与的介质。
本申请各部分操作所需的计算机程序编码可以用任意一种或多种程序语言编写,包括面向对象编程语言如Java、Scala、Smalltalk、Eiffel、JADE、Emerald、C++、C#、VB.NET、Python等,常规程序化编程语言如C语言、Visual Basic、Fortran 2003、Perl、COBOL 2002、PHP、ABAP,动态编程语言如Python、Ruby和Groovy,或其他编程语言等。该程序编码可以完全在用户计算机上运行、或作为独立的软件包在用户计算机上运行、或部分在用户计算机上运行部分在远程计算机运行、或完全在远程计算机或服务器上运行。在后种情况下,远程计算机可以通过任何网络形式与用户计算机连接,例如,局域网(LAN)或广域网(WAN)、或连接至外部计算机(例如通过因特网)、或在云计算环境中、或作为服务使用如软件即服务(SaaS)。
此外,除非权利要求中明确说明,本申请所述处理元素和序列的顺序、数字字母的使用、或其他名称的使用,并非用于限定本申请流程和方法的顺序。尽管上述披露中通过各种示例讨论了一些目前认为有用的发明实施例,但应当理解的是,该类细节仅起到说明的目的,附加的权利要求并不仅限于披露的实施例,相反,权利要求旨在覆盖所有符合本申请实施 例实质和范围的修正和等价组合。例如,虽然以上所描述的系统组件可以通过硬件设备实现,但是也可以只通过软件的解决方案得以实现,如在现有的服务器或移动设备上安装所描述的系统。
同理,应当注意的是,为了简化本申请披露的表述,从而帮助对一个或多个发明实施例的理解,前文对本申请实施例的描述中,有时会将多种特征归并至一个实施例、附图或对其的描述中。但是,这种披露方法并不意味着本申请对象所需要的特征比权利要求中提及的特征多。实际上,实施例的特征要少于上述披露的单个实施例的全部特征。
一些实施例中使用了描述属性、数量的数字,应当理解的是,此类用于实施例描述的数字,在一些示例中使用了修饰词“大约”、“近似”或“大体上”来修饰。除非另外说明,“大约”、“近似”或“大体上”表明所述数字允许有±20%的变化。相应地,在一些实施例中,说明书和权利要求中使用的数值参数均为近似值,该近似值根据个别实施例所需特点可以发生改变。在一些实施例中,数值参数应考虑规定的有效数位并采用一般位数保留的方法。尽管本申请一些实施例中用于确认其范围广度的数值域和参数为近似值,在具体实施例中,此类数值的设定在可行范围内尽可能精确。
针对本申请引用的每个专利、专利申请、专利申请公开物和其他材料,如文章、书籍、说明书、出版物、文档、物件等,特将其全部内容并入本申请作为参考。与本申请内容不一致或产生冲突的申请历史文件除外,对本申请权利要求最广范围有限制的文件(当前或之后附加于本申请中的)也除外。需要说明的是,如果本申请附属材料中的描述、定义、和/或术语的使用与本申请所述内容有不一致或冲突的地方,以本申请的描述、定义和/或术语的使用为准。
最后,应当理解的是,本申请中所述实施例仅用以说明本申请实施 例的原则。其他的变形也可能属于本申请的范围。因此,作为示例而非限制,本申请实施例的替代配置可视为与本申请的教导一致。相应地,本申请的实施例不限于本申请明确介绍和描述的实施例。
