具体实施方式
在下面的描述中阐述了很多具体细节以便于充分理解本申请。但是本申请能够以很多不同于在此描述的其它方式来实施,本领域技术人员可以在不违背本申请内涵的情况下做类似推广,因此本申请不受下面公开的具体实施的限制。
本申请第一实施例提供一种交通路网的描述方法。请参看图1,该图为本申请第一实施例的流程图。以下结合图1对本申请第一实施例进行详细说明。所述方法包括如下 步骤:
步骤S101:获得用于分隔同向行驶交通流的车道的数据特征。
本步骤用于获得用于分隔同向行驶交通流的车道的数据特征。
所述车道的数据特征包括以下至少一种数据特征:
所述车道的起点或终点的地理位置特征;
所述车道的方向特征;
所述车道的长度或宽度特征;
所述车道的车道类别特征;
所述车道所属路段的路段标识特征。
所述车道是在路段中,根据车行道指示线划分的,用来分隔同向行驶交通的交通流。车道空间位置使用车道中心线表示,在有车道数变化、车道分界线虚实线变化处进行打断。
下面的表1是使用表来描述车道数据特征的例子。表1中,路段是指城市大脑中的基础路段,路段根据重要道路重要路口确定。在交通领域,针对重要的道路和路口往往很少发生变化,变更频率远低于支小路,而支小路对分析交通规律也非重要的关注点。路口是指,路网中的一般为重要的,高流量的交叉路口点,如信号灯路口,两条道路等级为次干道以上的交叉点。

Figure PCTCN2019125853-appb-000002
表1车道的表结构
步骤S102:根据所述车道的数据特征,构建交通路网中的车道对象。
本步骤用于根据所述车道的数据特征,构建交通路网中的车道对象。
所述车道的数据特征可以参考表1中的属性特征。根据这些属性特征,可以使用C语言的结构体来构建车道对象,也可以采用C++或者JAVA等高级语言中的类来构建车道对象。
所述根据所述车道的数据特征,构建用于描述交通路网信息的车道对象,包括:
在所述车道的车道数发生变化的路段处针对所述车道进行切分,获得所述车道的渠化面;
针对所述渠化面进行编号,获得所述渠化面的编号信息;
根据所述车道的数据特征和所述渠化面的编号信息,构建用于描述交通路网信息的 车道对象。
所述渠化面(canalization),是指在车道数目固定的路段,将具有车流方向相同的所述路段的车道归类为一个平面。在车道数变化的路段处进行切分,形成多个连续的渠化面。
交通行业作为传统行业之一,自身拥有着较多但并不完善的设备采集的数据,在做决策判断时候往往很难被利用起来。
因此,将标清、高清地图路网信息,交警、路政局等单位路网信息映射为一套统一的按路段组织的路网结构数据,其他交通相关的动静态数据都在路段基础上进行加工处理,是解决这个问题的一种可行的解决方案。该解决方案主要是为了交通数据能更好服务上层的做决策以及态势分析等,制定了新的路网基础框架,它将是一个相对稳定的交通基础数据内容,并挂载了各种交通信息,同时完成了多方的数据融合。该解决方案的标清地图部分还是在一个较粗范围内来对路网进行表达,有时很难完全满足交通领域应用部分的需求,如信号灯优化、道路组织结构优化等上层应用,以及客户很多的设备采集的交通信息不止局限在到道路级别,他们需要更细到车道粒度的表达内容;在现实的交通管理上,设备设施则扮演的重要的角色,设备是交通信息的主要采集手段,设施是制定交通规则的主要手段。
高精地图是该解决方案中一个必不可少的重要组成部分。
图2描述了统一路网中心部分标清对象以及高清对象间在物理空间层面上,不同实体之间相互关系,在图2中渠化面会因为设施而打断,会因为道路形状的变更(车道数量的变化)而打断;车道则是依附在道路上的更细粒度的对象;检测器设备部分挂载到车道上。
所述针对所述渠化面进行编号,获得所述渠化面的编号信息,包括:
针对同一路段上的渠化面,从所述同一路段的上游路口出口车道开始,依次对所述同一路段上的渠化面进行递增编号,直到下游路口入口车道为止。
在高精地图中,在车道数变化的路段处进行切分,形成多个连续的渠化面。同一路段上的渠化面编号是连续的。编号规则是从上游路口出口车道开始,到下游路口入口车道结束(如东向西通行时,东为上游、西为下游),对渠化面从小到大顺序编号,取值从010开始。
初始编码为010,020,030,……,编码间隔10个序号。
所述交通路网的描述方法,还包括:
若所述同一路段上的第一渠化面分解为多个渠化面,则所述多个渠化面中的一个渠化面采用所述第一渠化面的编号,所述多个渠化面中的其他渠化面采用新增的编号。
若其中某个渠化面一拆为二,如020变更为两个渠化面,则顺着车流方向编码为020,021;渠化面只做拆分,不做合并。
在普通地图中,路段未切分渠化面。如需定义车道,可将渠化面编号可暂置为999。
步骤S103:根据所述车道对象,生成所述交通路网的数据结构。
本步骤用于根据所述车道对象,生成所述交通路网的数据结构。
所述交通路网的数据结构可以包括车道对象,还可以包括路段对象、路口对象以及岔口对象等。
步骤S104:将所述交通路网的信息数据挂载到所述数据结构中,获得针对所述交通路网的描述信息。
本步骤用于将所述交通路网的信息数据挂载到实例化的所述数据结构中,获得针对所述交通路网的描述信息。
所述实例化的所述数据结构包括实例化的所述车道对象的车道标识;
实例化的所述车道对象的车道标识采用如下步骤获得,包括:
获取实例化的所述车道对象所属的路段对象标识;
获取实例化的所述车道对象所属的渠化面编号;
获取实例化的所述车道对象的车道编号;
根据所述路段对象标识、所述渠化面编号和所述车道编号,获得实例化的所述车道对象的车道标识。
本实施例中,实例化的所述车道对象的车道标识的编码长度固定34个字符串,包括下面三部分:
(1)路段标识:当前车道所属路段,为长度29位字符串;
(2)渠化面序号:当前车道所属渠化面序号,长度3位字符串;
(3)车道序号:当前车道序号,长度2位字符串。
例如,河南中路(福州路-汉口路)路段中可能存在的车道标识有:
152C909H0R0152C609H170001001;
152C909H0R0152C609H170001002;
152C909H0R0152C609H170001003;
152C909H0R0152C609H170002001;
152C909H0R0152C609H170002002;
152C909H0R0152C609H170002003;
所述根据所述路段对象标识、所述渠化面编号和所述车道编号,获得实例化的所述车道对象的车道标识,包括:
将所述路段对象标识、所述渠化面编号与所述车道编号连缀,获得实例化的所述车道对象的车道标识。
这里,连缀即将路段对象标识、所述渠化面编号与所述车道编号等三部分的内容连接起来。
所述车道编号采用如下规则获得,包括:
在车道所属的路段中,沿车流方向从最左侧车道开始,依次对所述车道进行递增编号,直到最右侧车道为止;
或者,若在车道所属的路段左侧新增车道,则新增车道的编号小于所述新增车道的右侧车道编号;
或者,若在车道所属的路段右侧新增车道,则新增车道的编号大于所述新增车道的左侧车道编号。
本实施例中,在路段中从内向外对车道进行编号。最左侧车道编号为11,向右依次递增,取值为(11~99)。路段中不同渠化面存在车道数变化时,通过车道序号来反应车道上下游关系;路段左侧新增车道时,车道序号递减排列(10,9,8……)
常见场景举例:
上游渠化面车道为:{11,12,13,14},下游渠化面车道为:{12,13,14},表示11,12车道在下游渠化面产生车道合流;
上游渠化面车道为:{12,13,14},下游渠化面车道为:{11,12,13,14},表示12车道在下游渠化面产生车道分流;
渠化面车道序号为:{9,10,11,12,13,14},表示路段左侧新扩充了2条车道。
所述交通路网的描述方法,还包括:

在现实的交通管理上,设备设施则扮演的重要的角色,交通设备是交通信息的主要采集手段,交通设施是制定交通规则的主要手段。
