Description

交通信息处理及相关设备 技术领域
本发明涉及电子技术领域，尤其涉及一种交通信息处理及相关设备。
背景技术
智能交通系统(Intelligent Transportation System，ITS)是将先进的信息技术、数据通讯传输技术、电子传感技术、控制技术及计算机技术等有效地集成运用于整个地面交通管理系统而建立的一种在大范围内、全方位发挥作用的，实时、准确、高效的综合交通运输管理系统，可以实现将交通信息传输给交通参与对象，例如，将交叉路口信号灯切换信息通知给行人、车辆。
然而，在现有的技术方案中，智能交通系统主要采用广播方式向交通参与对象发送信息。例如：为了实现将某个车辆当前的位置、方向、速度等信息通知其它相关车辆，若基于专用短程通信(Dedicated Short Range Communications，DSRC)技术，则该车辆将这些信息通过无线局域网络直接向周围其它车辆广播；若基于支持车辆的长期演进(Long Term Evolution for Vehicle，LTE-V)技术，则该车辆将这些信息通过无线蜂窝网络提交给基站，再由基站通过无线蜂窝网络向周围其它车辆广播。
在这种情形下，交通信息可以能会传递给实际上不需要该交通信息的交通参与对象，而实际上真正需要该交通信息的交通参与对象却接收不到该交通信息。因此，如何精确地确定交通参与对象并有针对性的传输交通信息，是一个值得考虑的问题。

具体实施方式
下面结合本发明实施例中的附图对本发明实施例进行描述。
请参见图1，图1是本发明实施例提供的一种智能交通系统的系统架构示意图，该智能交通系统包括至少一个交通控制单元(Traffic Control Unit，TCU)，每个交通控制单元存在相应的管理区域。TCU主要的职责是负责协调其管理区域内的交通参与对象的活动，并与其相邻的TCU进行通信，其中，交通参与对象可以包括车辆、路侧基础设施、行人等，相邻的TCU指的是与该TCU对应的管理区域相邻的管理区域所对应的TCU。
在图1所示的智能交通系统中，包括TCU 10、TCU 20、TCU 30以及TCU 40，分别对应的管理区域为管理区域1、管理区域2、管理区域3以及管理区域4，以TCU 10为例，TCU 10负责协调管理区域1内的交通参与对象的活动，以及与其相邻的TCU 20和TCU 30进行 通信。
基于该系统架构，在一种可能的设计中，每个TCU在部署或更新时，可以通知其相邻的TCU自己本身的标识，以使每个TCU都能获知相邻的TCU的存在。在另一种可能的设计中，每个TCU在部署或更新时，可以通知其相邻的TCU自己本身的标识以及管理区域，以使每个TCU都能获知相邻的TCU以及各相邻的TCU的管理区域。
本发明实施例所涉及的交通场景可以包括但不限定于：交通信号通知场景，需要将某个交叉路口信号灯切换信息通知将要进入该路口的车辆和行人；前方拥堵提醒场景，需要将当前的拥堵信息通知特定距离或特定路口数内的车辆和行人；危险障碍告警场景，需要将当前的危险障碍信息通知特定距离或特定路口数内的车辆和行人；紧急车辆提示场景，需要将紧急车辆通知给紧急车辆行驶方向上及与当前位置相距一定距离内的车辆和行人；弱势交通参与对象预警场景，需要将该交通参与对象当前所在位置通知给弱势交通参与对象周围连通的道路上、向该弱势交通参与对象接近方向、并且到该弱势交通参与对象特定距离内的车辆和行人；车辆预防碰撞场景，需要向某个车辆警示其周围运动状态与其可能存在碰撞风险的物体信息。
请参见图2，图2是本发明实施例提供的一种交通信息处理方法的流程示意图，该方法包括但不限于如下步骤：
S201，第一TCU获取交通应用类型和交通目标对象的第一交通信息。
交通应用类型用于指示待处理的交通场景。例如，紧急车辆提示的交通应用类型指示第一TCU待处理的交通场景为第一TCU需要向紧急车辆方向上的其他车辆进行提示，以使其他车辆为紧急车辆让道。第一交通信息为交通目标对象的信息，其中，交通目标对象可以是行人、车辆、交通基础设施等对象。交通目标对象的第一交通信息可以是包括各种与交通目标对象有关的交通信息，例如可以包括交通目标对象的标识、位置、状态的信息，也可以包括交通环境信息、灾害信息等等。
第一TCU在获取交通应用类型和交通目标对象的第一交通信息时，有以下几种可能的实施场景：
在第一种可能的实施场景中，S201可以具体为：第一TCU根据预设条件，获取交通目标对象的第一交通信息以及交通应用类型。
预设条件可以是预先在第一TCU中设置的定时时间、信息类型、指令类型等。当第一TCU检测到预设条件满足时，就可以触发获取交通目标对象的第一交通信息以及交通应用类型的动作。例如，预设条件为到达预设的第一时间，则第一TCU就可以在第一时间到达时获取交通目标对象的第一交通信息以及交通应用类型的动作。
交通目标对象的第一交通信息可以是第一TCU预先通过交通目标对象、其他TCU或者网络单元等收集到的，这里不作具体限定。
第一TCU在获取到第一交通信息后可以分析确定出相应的交通应用类型，也可以根据预设条件确定交通应用类型，这里的交通应用类型可以通过交通应用类型的标识来表示。从而，第一TCU就可以获取到交通应用类型和交通目标对象的第一交通信息。例如，若第一交通信息为紧急车辆的位置、状态等相关信息时，第一TCU可以根据第一交通信息确定出交通应用类型为紧急车辆提示应用类型。
进一步地，第一TCU可以根据交通应用类型和交通目标对象的第一交通信息创建该交通 应用类型对应的交通应用实例。交通应用实例是指交通应用的一次实际运行，例如交通信号通知应用的一次运行就是交通信号通知应用的实例。在实例的创建过程中，第一TCU可以为该交通应用实例分配一个实例标识，该实例标识可以唯一的表示该交通应用实例。
例如，第一交通信息中携带交通信号的信息(标识、位置、相位状态、当前相位状态的剩余持续时间等)，则第一TCU可以分析确定该第一交通信息对应的交通应用类型为交通信号灯信息的通知应用类型，创建交通信号通知应用实例，并分配该交通信号通知应用实例的实例标识。
在第二种可能的实施场景中，S201可以具体为：第一TCU接收交通目标对象的第一交通信息，并根据交通目标对象的第一交通信息确定交通应用类型。
第一TCU根据接收到的第一交通信息中的内容，可以分析确定出第一交通信息对应的交通应用类型。从而，第一TCU就可以获取到交通应用类型和交通目标对象的第一交通信息。进一步地，第一TCU可以根据交通应用类型和交通目标对象的第一交通信息创建该交通应用类型对应的交通应用实例。
在第三种可能的实施场景中，S201可以具体为：第一TCU根据接收到的交通目标对象的交通应用请求，确定交通目标对象的第一交通信息以及交通应用类型。
交通应用请求可以包括交通目标对象的第一交通信息和请求类型，其中，请求类型用于确定交通应用类型。
第一TCU在接收到交通目标对象的交通应用请求后，可以根据交通应用请求中的请求类型确定出对应的交通应用类型，从而，第一TCU就可以获取到交通应用类型和交通目标对象的第一交通信息。例如，交通应用请求中的请求类型为路径规划业务请求，第一TCU根据路径规划业务请求可以确定对应的交通应用类型为路况查询应用类型。进一步地，第一TCU可以根据交通应用类型和交通目标对象的第一交通信息创建该交通应用对应的交通应用实例。
需要说明的是，交通目标对象的交通应用请求可以是交通目标对象自身向第一TCU发送的，也可以是其他交通对象向第一TCU发送的。例如，交通目标对象为车辆，想要获知其周围盲区的物体信息时，交通目标对象可以直接向第一TCU发送请求类型为盲区物体告警的交通应用请求；交通目标对象为残疾人，其他交通对象为路侧监控设备，当路侧监控设备监测到残疾人出现时，可以向第一TCU发送请求类型为残疾人提醒的针对交通目标对象(残疾人)的交通应用请求。
在第四种可能的实施场景中，S201可以具体为：第一TCU根据接收来自与所述第一TCU相邻的第三TCU的交通应用类型和交通目标对象的第一交通信息。
交通应用类型和交通目标对象的第一交通信息可以是与第一TCU相邻的第三TCU在初始触发交通应用实例，确定了交通应用类型和交通目标对象的第一交通信息后发送给第一TCU的；交通应用类型和交通目标对象的第一交通信息也可以是与第一TCU相邻的第三TCU收到其相邻TCU发送的交通应用类型和交通目标对象的第一交通信息后传递给第一TCU的。从而第一TCU可以直接得到交通应用类型和交通目标对象的第一交通信息。
进一步地，第一TCU可以根据交通应用类型和交通目标对象的第一交通信息创建该交通应用对应的交通应用实例。需要说明的是，在该实施场景中，第一TCU相邻的第三TCU还可以向第一TCU发送创建交通应用实例时分配的实例标识。因此第一TCU在创建交通应用实例时，无需分配新的实例标识。可选的，第一TCU在创建交通应用实例时可以为该交通应用实例分配物理资源，例如，内存资源、处理单元(Central Processing Unit，CPU)资源、存储 资源等等。
S202，第一TCU根据交通应用类型和交通目标对象的第一交通信息，确定交互覆盖区域。
交互覆盖区域用于指示待处理的交通场景涉及的地理区域。例如待处理的交通场景是交通信号灯的信息的通知场景，那么涉及的地理区域就可以是该交通信号灯管控的道路中的部分区域，那么这部分区域就可以为交互覆盖区域。
第一TCU确定交通应用类型和交通目标对象的第一交通信息之后，可以根据交通应用类型和交通目标对象的第一交通信息确定出交互覆盖区域。具体实现中，第一TCU可以根据交通应用类型和交通目标对象的第一交通信息以及地图信息确定交互覆盖区域。其中，第一交通信息可以包括交通目标对象的位置信息，或者，也可以包括交通目标对象的位置信息和状态信息。
在一种可能的实施场景中，第一交通信息可以包括交通目标对象的位置信息，交通目标对象的位置信息具体可以为交通目标对象的当前位置。第一TCU根据交通应用类型和交通目标对象的第一交通信息以及地图信息，将交通目标对象的当前位置为起点的第一距离阈值内的地理区域确定为交通应用的交互覆盖区域。其中，第一距离阈值可以是根据交通应用类型确定的，即不同的交通应用类型可以对应不同的第一距离阈值。
具体来说，交通目标对象的当前位置确定了交互覆盖区域的起点，而交通应用类型可以确定第一距离阈值，那么第一TCU根据交通应用类型结合地图信息就可以确定从该起点向某个特定方向或者特定道路延伸第一距离阈值后的区域，即确定以交通目标对象的当前位置为起点的第一距离阈值内的地理区域作为交互覆盖区域。
举例来说，假设交通目标对象为交通信号灯S，交通应用类型为交通信号灯信息的通知应用类型，交通目标对象的位置信息为交通信号灯S的当前位置A。假设交通信号灯信息的通知应用类型指示的是将某一个交通信号灯管控的道路上距离交通信号灯S2km(第一距离阈值)内的区域作为交互覆盖区域，则第一TCU就可以将交通信号灯S的当前位置a作为起点，结合地图信息确定交通信号灯S管控的道路上距离交通信号灯S2km内的地理区域，将该地理区域确定为交通信号灯信息的通知应用类型指示的交通场景对应的交互覆盖区域。
在另一种可能的实施场景中，第一交通信息可以包括交通目标对象的位置信息和状态信息。其中，状态信息可以指速度、角速度、加速度、运动方向等。则第一TCU需要根据交通应用类型和交通目标对象的第一交通信息以及地图信息，将交通目标对象的当前位置为起点的特定方向上的第一距离阈值内的地理区域确定为交互覆盖区域。与上一种可能的实施场景不同的是，从交通目标对象的当前位置为起点向外延伸的第一距离阈值、特定方向等交互覆盖区域的参数，不仅由交通应用类型和地图信息确定，还需要结合交通目标对象的状态信息。
举例来说，假设交通目标对象为紧急车辆E，交通应用类型为紧急车辆提示应用类型，交通目标对象的位置信息为紧急车辆E的当前位置b，状态信息包括紧急车辆E的行驶方向、行驶速度、行驶加速度等。假设紧急车辆提示应用类型指示的是将紧急车辆行驶的道路上5分钟内紧急车辆会到达的区域作为交互覆盖区域，则第一TCU可以将紧急车辆E的当前位置b作为起点，根据紧急车辆E的行驶速度、行驶加速度等确定出5分钟内紧急车辆E的行驶的距离为1km，然后结合地图信息以及紧急车辆E的行驶方向，将紧急车辆行驶的道路上紧急车辆E的行驶方向上距离紧急车辆E的当前位置b1km的地理区域确定为紧急车辆提示应用类型指示的交通场景的交互覆盖区域。
S203，第一TCU根据交互覆盖区域以及第一TCU的管理区域确定是否存在第一区域， 若存在，则执行S204，若不存在，则执行S207。
第一区域为第一TCU的管理区域与交互覆盖区域重叠的区域。第一TCU可以将第一TCU的管理区域与交互覆盖区域进行比较，以确定两者之间是否存在重叠的区域。若存在重叠的区域，则确定存在第一区域，执行步骤204；若不存在重叠的区域，则确定不存在第一区域，则可以将交通应用类型和交通目标对象的第一交通信息发送给第二TCU，则执行S207，第二TCU的定义在S207中详细说明。在本发明实施例中，第一TCU的管理区域可以是在对第一TCU进行部署时设定的，从而第一TCU可以获知自身的管理区域。
S204，第一TCU确定第一区域中的交通参与对象。
交通参与对象可以指在第一TCU确定的第一区域中与交通应用类型和交通目标对象的第一交通信息相关的交通参与对象。可选的，交通参与对象可以指获取到交通应用类型和交通目标对象的第一交通信息的某个时间范围内出现在第一区域的交通参与对象，也可以指交通应用类型特别针对的某几种交通参与对象，例如交通灯等，这里不作具体限定。
可选的，第一TCU可以将预设时间内在第一区域中出现的可通信对象确定为交通参与对象。其中，预设时间可以是从当前时刻起的一段时间，可通信对象为具有与第一TCU进行发送和接收消息的通信功能的对象。由于第一交通信息的时效性不同，对于不同应用类型、不同第一交通信息，可以设定不同的预设时间。例如，第一交通信息为自然灾害信息，则可以从当前时刻算起的3小时、5小时内在第一区域中出现的交通参与对象确定为交通参与对象。又如，第一交通信息为交通信号灯信息，则可以在从当前时刻算起的信号灯当前相位状态的剩余持续时长(30秒、50秒等)内在第一区域中出现的交通参与对象确定为交通参与对象。
进一步的，S203或S204之后，还可以执行S206，以确定交互覆盖区域是否超出第一TCU的管理区域。
S205，第一TCU为交通参与对象提供交互支持。
本发明实施例中的交互支持可以包括：第一TCU向交通参与对象发送交通目标对象的第一交通信息；或，第一TCU接收来自交通参与对象的第二交通信息并将第二交通信息发送给所述交通目标对象。具体的实施方式可以参见图3a和图3b的具体介绍。
可选的，第一TCU可以根据交通应用类型确定为交通参与对象提供交互支持。例如，若交通应用类型为指示待处理的交通信号灯通知场景，则所采用的交互支持为向交通参与对象发送第一交通信息，若交通应用类型为指示待处理的盲区物体告警场景，则所采用的交互支持为接收交通参与对象发送的第二交通信息，并将该第二交通信息发送给交通目标对象。
从而，第一TCU就可以通过确定交通场景对应的交互覆盖区域，精确地确定出第一TCU自身的管理区域中真正涉及该交通场景的交通参与对象并提供交互支持，从而达到有针对性的传递交通信息的目的。
进一步的，S205之后还包括S206：
S206，第一TCU根据交互覆盖区域以及第一TCU的管理区域确定是否存在第二区域，若存在，则执行S207。
第二区域为交互覆盖区域中与第一TCU的管理区域不重叠的区域。第一TCU可以将第一TCU的管理区域与交互覆盖区域进行比较，以确定交互覆盖区域是否存在与第一TCU的管理区域不重叠的区域，。若存在不重叠的区域，即存在第二区域，则执行步骤207。
S207，第一TCU向第二TCU发送交通应用类型和交通目标对象的第一交通信息。
由于在系统结构中提到的两种系统架构部署设计，本发明中的第二TCU也存在两种含义。
在第一种设计中，第一TCU仅知道自己的管理区域以及其相邻的TCU的存在，并不知道其相邻的TCU分别对应的管理区域，因此，这里的第二TCU可以为与第一TCU相邻的所有TCU。因此，在该实施例中，第一TCU向第二TCU发送交通应用类型和交通目标对象的第一交通信息，即向与第一TCU相邻的所有TCU发送交通应用类型和交通目标对象的第一交通信息。
在第二种设计中，第一TCU知道自身以及所有其相邻的TCU分别对应的管理区域，因此第一TCU就可以将与第一TCU相邻的TCU中管理区域与交互覆盖区域存在重叠区域的TCU确定为第二TCU。也就是说，这种实施场景中的第二TCU的管理区域是与交互覆盖区域存在重叠区域的。
需要说明的是，在S201中提到的第四种可能的实施场景中，第一TCU是接收来自与第一TCU相邻的第三TCU的交通应用类型和交通目标对象的第一交通信息的。在这种实施场景中，第一TCU可以在除第三TCU以外的第一TCU的相邻TCU中确定第二TCU。具体来说，在第一种设计中，第一TCU向除第三TCU以外的与第一TCU相邻的TCU发送交通应用类型和交通目标对象的第一交通信息；在第二种设计中，第一TCU向除第三TCU以外的第二TCU发送交通应用类型和交通目标对象的第一交通信息。就是说，第一TCU不再向第三TCU回传交通应用类型和交通目标对象的第一交通信息，避免通信资源和处理资源的浪费。
进一步地，第一TCU还可以将自己分配的实例标识或者从第三TCU获取到的实例标识发送给第二TCU。可选的，第一TCU还可以将其获知的其他与该交通场景有关的交通环境信息等发送给第二TCU。
进一步地，当与第一TCU相邻的TCU更新时，可以向第一TCU发送更新后的标识或，更新后的标识以及管理区域。
S208，第二TCU对交通应用类型和交通目标对象的第一交通信息进行处理。
第二TCU对交通应用类型和交通目标对象的第一交通信息的处理过程可以参考S202-S208。
从而，第一TCU在确定交互覆盖区域存在与第一TCU自身的管理区域不重叠的区域时，可以根据其了解的与自身相邻的TCU的管理区域情况，向第一TCU相邻的TCU或者第一TCU相邻的TCU中管理区域与交互覆盖区域存在重叠区域的TCU(即第二TCU)发送交通应用类型和交通目标对象的第一交通信息，以使第二TCU或与第一TCU相邻的TCU能够继续确定交互覆盖区域并为相关的交通参与对象提供交互支持。
进一步，S208之后还可以包括：
S209，第二TCU发送向第一TCU发送第一消息。
第一消息用于指示第二TCU确定已接收到交通应用类型和交通目标对象的第一交通信息，这样的反馈机制可以使第一TCU就无需启动重传等流程。需要说明的是，这里的第二TCU也包括步骤S207中说明的两种第二TCU的情况。
本发明实施例第一TCU通过确定交通场景对应的交互覆盖区域，可以精准的确定在第一TCU的管理区域中涉及到该交通场景的交通参与对象并为之提供交互支持，从而达到有针对性的传递交通信息的目的，有效减少通信资源和处理资源的浪费。
在本发明实施例中，步骤S205中第一TCU为交通参与对象提供交互支持，可以参考图 3a和图3b中任意一种实现方式。具体参见以下介绍。
请参见图3a，图3a为本发明实施例提供了一种提供交互支持的流程示意图。在图3a的实施场景中，第一TCU为交通参与对象提供的交互支持是向交通参与对象发送交通目标对象的第一交通信息，具体可以执行以下S301-S303的步骤。
S301，第一TCU向交通参与对象发送交通目标对象的第一交通信息。
其中，在步骤S201第一TCU获取交通应用类型和交通目标对象的第一交通信息的步骤中，可以获知第一交通信息可以是通过不同的方式获取到的，这里不再赘述。通过向交通参与对象发送第一交通信息以便于交通参与对象有效利用该第一交通信息。
例如，若第一交通信息为前方拥堵的位置信息，交通参与对象为附近车辆，则第一TCU可以向附近车辆发送前方拥堵的位置信息，以使交通参与对象在接收到该信息之后，车辆用户可以根据自己的位置及需求确定是否调整前行路径。
在一种可能的实现场景中，第一TCU所发送的是第一TCU处理后的第一交通信息。例如，若第一交通信息为交通信号灯S的位置信息和状态信息，这里的状态信息为信号灯S保持红灯的剩余时长为45秒，则第一TCU可以根据接收到第一交通信息，以及信息处理时长，生成第一交通信息，如，信息处理时长，包括交互覆盖区域的确定时长、交通参与对象的确定时长、与交通参与对象传输信息的传输时长等等，若信息处理时长为5s，则生成的第一交通信息为信号灯S的位置信息以及保持红灯的剩余时长为40秒的状态信息。
相应的，交通参与对象接收所述交通目标对象的第一交通信息。
S302，第一TCU向交通参与对象发送交通环境信息。
其中，第一TCU可以获取交通环境信息，并向交通参与对象发送该交通环境信息。其中，交通环境信息可以包括但不限定于天气信息、交通道路是否有积水等。可选的，第一TCU可以向天气监控设备获取天气信息，可以向道路监控设备获取交通道路是否有积水的信息。
相应的，交通参与对象接收所述交通环境信息。
可选的，第一TCU还可以向交通参与对象发送不同于第一交通信息的交通差异信息，这里的交通差异信息不限于步骤302中的交通环境信息。在一种可选的实现方式中，第一TCU在确定发送第一交通信息和交通差异信息之后，第一TCU可以一次性将第一交通信息和交通差异信息发送给交通参与对象；或者，也可以分两次分别发送第一交通信息和交通差异信息，本发明实施例对此不做限定。
S303，交通参与对象向第一TCU发送第三消息。
相应的，第一TCU接收第三消息，第三消息用于指示交通参与对象已确认接收第一交通信息。第三消息可以是针对第一交通信息和交通环境信息中至少一个信息的反馈。
请参见图3b，图3b为本发明实施例提供了另一种提供交互支持的流程示意图。在图3b实施场景中，第一TCU为交通参与对象提供的交互支持是收集交通参与对象的第二交通信息然后发送给交通目标对象，具体可以执行以下S304-S308的步骤。
S305，交通参与对象向第一TCU发送第二交通信息。
交通参与对象可以定时的向第一TCU上报第二交通信息，也可以是经过第一TCU发送的指示信息后，向第一TCU发送第二交通信息的，这里不作具体限定。其中，交通参与对象可以为移动对象(例如移动的车辆)，也可以为固定对象(例如交通信号灯)。第二交通信息 可以包括交通参与对象的位置信息或状态信息，状态信息可以包括方向、速度、加速度、角速度等，状态信息也可以包括相位状态信息、持续时间信息等，例如交通信号灯的前进、停止以及对应的持续时间。
可选的，S305之前还可以包括S304：
S304，第一TCU向交通参与对象发送指示信息。
通过发送指示信息，可以使交通参与对象反馈第二交通信息。
S305之后，还可以执行S306-S308，需要说明的是，S306和S307在执行顺序上并没有先后之分。
S306，第一TCU向交通参与对象发送第四消息。
在第一TCU接收到第二交通信息之后，可以向交通参与对象发送第四消息，第四消息用于指示第一TCU已确定接收第二交通信息。
相应的，交通参与对象接收第四消息，以确定第一局部TCU已接收到该第二交通信息。
S307，第一TCU向交通目标对象发送第二交通信息。
第一TCU可以将从交通参与对象接收到的第二交通信息发送给交通目标对象，以使交通目标对象有效利用该信息。例如，假设交通目标对象为碰撞发生率高的路口的第一车辆，交通参与对象为与第一车辆相距一定距离范围内的第二车辆，为了减少碰撞，第一TCU可以将第二车辆的位置信息、状态信息发送至第一车辆，以使第一车辆的用户及时了解该路口的其他车辆的信息，还可以根据实际需求调整自身的驾驶行为。
进一步的，当第一TCU接收的是与第一TCU相邻的第三TCU发送的交通应用类型和交通目标对象的第一交通信息时，第一TCU可以经第三TCU将第二交通信息发送给交通目标对象。如果第三TCU也是接收的是与第三TCU相邻的第四TCU发送的交通应用类型和交通目标对象的第一交通信息，那么可以进一步经第四TCU将第二交通信息发送给交通目标对象。
S308，交通目标对象向第一TCU发送第五消息。
在交通目标对象接收到第二交通信息之后，可以向第一TCU发送第五消息，第四消息用于指示交通目标对象已确定接收第二交通信息。
相应的，第一TCU接收第五消息，以确定交通目标对象已接收到该第二交通信息。
下面就一些实际应用场景，举例说明本发明实施例的交通信息处理方法。
在图3a的实施场景中，第一TCU为交通参与对象提供的交互支持是向交通参与对象发送交通目标对象的第一交通信息，其中交通目标对象可以为固定部署或相对固定的对象也可以为移动的对象。
以交通信号灯信息的通知应用类型为例说明固定部署的交通目标对象的交通信息处理方法。
如图4所示，第一TCU为TCU A，其负责的管理区域为管理区域A，交通信号灯S固定部署于TCU A的负责区域内。交通信号灯S的控制单元主动或者在TCU A请求后，向TCU A发送交通信号灯S信息(即上述实施例中的第一交通信息)。交通信号灯S信息可以包括交通信号灯S的标识、位置信息和当前相位状态信息。相位状态信息可以包括通行、停止、减 速、限速、转弯等当前信号的类型以及当前信号的剩余持续时间。TCU A可以向交通信号灯S的控制单元发送用于指示已确认接收交通信号灯S信息的消息。
交通信号灯S信息触发TCU A根据交通信号灯S信息确定交通应用类型，交通信号灯S作为交通目标对象。TCU A根据该交通信号灯信息的通知应用类型和交通信号灯S信息，结合地图信息确定该交通信号灯信息的通知应用类型对应的交互覆盖区域。设交通信号灯信息的通知应用类型指示的是将某一个交通信号灯管控的道路上距离该交通信号灯2km内的区域作为交互覆盖区域，那么TCU A可以将交通信号灯S的位置作为起点，以交通信号灯S管控的如图4所示的道路区域DL1上距离交通信号灯S2km的区域，作为交通信号灯信息的通知应用类型的交互覆盖区域。
可以看出，TCU A的管理区域A与交互覆盖区域存在重叠的区域，即存在第一区域，则TCU A进一步确定其管理区域A内实际涉及该交互的交通参与对象P(图4中的汽车)。根据交通信号灯信息的通知应用类型，TCU A采用的交互支持方法可以是向交通参与对象P发送交通信号灯S信息，以便交通参与对象P根据交通信号灯S行动，例如通行、停止、转弯或者调整速度。交通参对象者P可以向TCU A发送用于指示已确认接收交通信号灯S信息的消息。
进一步地，TCU A可以确定该交互覆盖区域中存在与TCU A的管理区域A不重叠的区域，即存在第二区域，可以直接将相邻的TCU B和TCU C确定为第二TCU，也可以在已知TCU B和TCU C对应的管理区域的情况下，确定TCU B和TCU C对应的管理区域与交互覆盖区域存在重叠区域，则确定涉及该交互的第二TCU为TCU B和TCU C。
TCU A向TCU B和TCU C发送交通应用类型和交通目标对象的第一交通信息。当TCU B或TCU C收到TCU A发送的交通应用类型和交通目标对象的第一交通信息时，TCU B和TCU C分别对交通应用类型和交通目标对象的第一交通信息进行处理。TCU B或TCU C可以回复TCU A用于指示已确认接收该交通应用类型和交通目标对象的第一交通信息的消息。TCU B和TCU C对交通应用类型和交通目标对象的第一交通信息的处理流程与上述TCU A的处理流程相同，但TCU B或TCU C不再发送交通应用类型和交通目标对象的第一交通信息给TCU A。
同理的，在车内标牌显示应用中，固定部署的交通标志作为交通目标对象，由交通标志的控制单元向TCU发送交通标志信息。交互覆盖区域包括该交通标志负责管控的道路上、并且到该交通标志特定距离或者特定路口数内的区域。TCU向该交互覆盖区域内的交通参与对象发送交通标志信息，以使交通参与对象可以在接收到交通标志信息后进行车内显示。
在前方拥堵提醒应用类型中，突发出现的拥堵报告点作为交通目标对象，由附近路侧监控设备或经过的车辆、车辆用户、行人等向TCU发送拥堵报告信息。交互覆盖区域包括该拥堵报告点周围连通的道路上、向该拥堵报告点接近方向、并且到该拥堵报告点特定距离或者特定路口数内的区域。TCU向该交互覆盖区域内的交通参与对象发送拥堵报告信息，以使交通参与对象可以在接收到拥堵报告信息后调整前行路径。
在危险障碍告警应用类型中，突发出现的路上障碍物作为交通目标对象，由附近路侧监控设备或经过的车辆、车辆用户、行人等向TCU发送道路障碍信息。交互覆盖区域包括该障碍物所在道路上、向该障碍物接近方向、并且到该障碍物特定距离或者特定路口数内的区域。TCU向该交互覆盖区域内的交通参与对象发送道路障碍信息，以使交通参与对象在接收到道路障碍信息后在前行时警惕该障碍物。
以紧急车辆提示应用类型为例说明移动的交通目标对象的交通信息处理方法。
设第一TCU为TCU A，紧急车辆E在TCU A对应的管理区域A内移动。紧急车辆E自己或者附近路侧监控设备发现紧急车辆E后，向TCU A发送紧急车辆E信息(即上述实施例中的第一交通信息)。紧急车辆E信息可以包括紧急车辆E的标识、当前位置和运动状态。运动状态可以包括方向、速度、加速度、角速度等。TCU A可以回复紧急车辆E或者附近路侧监控设备用于指示已确认接收紧急车辆E信息的消息。
紧急车辆E信息触发TCU A根据紧急车辆E信息确定交通应用类型，交通目标对象为紧急车辆E。TCU A根据该紧急车辆提示应用类型和紧急车辆E信息，结合地图信息确定交互覆盖区域。该交互覆盖区域包括紧急车辆E行驶前方道路上、并且到紧急车辆E当前位置特定距离(例如300m)内的区域。TCU A根据该交互覆盖区域，结合其所了解的TCU负责区域，确定涉及该交互的第二TCU。
若TCU A的管理区域A与交互覆盖区域存在重叠的区域，即存在第一区域，则TCU A进一步确定其对应的管理区域内实际涉及该交互的交通参与对象P，可以是车辆、车辆用户和/或路侧基础设施。根据紧急车辆提示应用类型，TCU A采用的交互支持方法可以是向交通参与对象P发送紧急车辆E信息，以便交通参与对象P为紧急车辆E的前行提供便利，例如在其行驶前方道路上的车辆为其让行，或者在其行驶前方道路上的交通信号等路侧基础设施为其调整相位状态。交通参与对象P可以回复TCU A用于指示已确认接收紧急车辆E信息的消息。
进一步地，若TCU A确定该交互覆盖区域中存在与TCU A的管理区域A不重叠的区域，即存在第二区域，可以直接将相邻的TCU确定为第二TCU，也可以在已知相邻TCU对应的管理区域的情况下，确定管理区域与交互覆盖区域存在重叠区域的第二TCU。
TCU A向第二TCU发送交通应用类型和交通目标对象的第一交通信息。当第二TCU收到TCU A发送的交通应用类型和交通目标对象的第一交通信息时，第二TCU对交通应用类型和交通目标对象的第一交通信息进行处理。第二TCU可以回复TCU A对用于指示已确认接收交通应用类型和交通目标对象的第一交通信息的消息。第二TCU对交通应用类型和交通目标对象的第一交通信息进行处理的处理流程与上述TCU A的处理流程相同，但第二TCU不再发送交通应用类型和交通目标对象的第一交通信息给TCU A。
同理的，在异常车辆告警应用类型中，突发出现并可能移动的异常车辆作为交通目标对象，由异常车辆自己、附近路侧监控设备或经过的车辆、车辆用户、行人等向TCU发送异常车辆信息。交互覆盖区域包括该异常车辆行驶后方道路上、并且到该异常车辆特定距离内的区域。TCU向该交互覆盖区域内的交通参与对象发送异常车辆信息，以使交通参与对象，以使交通参与对象可以在接收到异常车辆信息后在前行时警惕与其碰撞。
在弱势交通参与对象预警应用类型中，突发出现并可能移动的弱势交通参与对象(例如行人、骑行者等)为交通目标对象，由弱势交通参与对象自己、附近路侧监控设备经过的车辆、车辆用户、行人等向TCU发送弱势交通参与对象信息。交互覆盖区域包括该弱势交通参与对象周围连通的道路上、向该弱势交通参与对象接近方向、并且到该弱势交通参与对象特定距离内的区域。TCU向该交互覆盖区域内的交通参与对象发送弱势交通参与对象信息，以使交通参与对象，以使交通参与对象可以在接收到弱势交通参与对象信息后在前进、后退、转弯等时警惕与其碰撞。
在图3b的实施场景中，第一TCU为交通参与对象提供的交互支持是收集交通参与对象的第二交通信息然后发送给交通目标对象。
以盲区物体告警应用类型为例说明图3b的实施场景中的交通信息处理方法。
目标车辆V在TCU A对应的管理区域A内移动。当目标车辆V向TCU A发送盲区物体告警信息请求时，TCU获取目标车辆V信息并根据盲区物体告警信息请求的请求类型确定对应的盲区物体告警应用类型。目标车辆V作为交通目标对象。由目标车辆V向TCU A发送目标车辆V信息(即上述实施例中的第一交通信息)。目标车辆V信息可以包括目标车辆V的标识、当前位置和运动状态。运动状态可以包括方向、速度、加速度、角速度等。
TCU A根据盲区物体告警应用类型和目标车辆V信息，结合地图信息确定交互覆盖区域。该交互覆盖区域包括目标车辆V周围、不在目标车辆V可观察方向上、并且到目标车辆V特定距离(例如100m)内的区域。TCU A根据该交互覆盖区域，结合其所了解的TCU负责区域，确定涉及该交互的第二TCU。
若TCU A的管理区域A与交互覆盖区域存在重叠的区域，即存在第一区域，则TCU A进一步确定其对应的管理区域内实际涉及的交通参与对象P，可以是移动或固定物体。交通参与对象P自己或者附近路侧监控设备发现交通参与对象P或者TCU A向交通参与对象请求后，向TCU A发送交通参与对象P信息(即上述实施例中的第二交通信息)。交通参与对象P信息可以包括交通参与对象P的位置和运动状态。运动状态可以包括方向、速度、加速度、角速度等。TCU A向目标车辆V发送交通参与对象P信息，以便目标车辆V了解其盲区内的物体而警惕与其碰撞，例如纠正或放弃向盲区的移动。目标车辆V可以回复TCU用于指示已确认接收交通参与对象P信息的消息。
进一步地，若TCU A确定该交互覆盖区域中存在与TCU A的管理区域A不重叠的区域，即存在第二区域，可以直接将相邻的TCU确定为第二TCU，也可以在已知相邻TCU对应的管理区域的情况下，确定管理区域与交互覆盖区域存在重叠区域的第二TCU。
TCU A向第二TCU发送交通应用类型和交通目标对象的第一交通信息。当第二TCU收到TCU A发送的交通应用类型和交通目标对象的第一交通信息时，第二TCU对交通应用类型和交通目标对象的第一交通信息进行处理。第二TCU可以回复TCU A用于指示已确认接收该盲区物体告警应用类型和目标车辆V信息的消息。第二TCU对交通应用类型和交通目标对象的第一交通信息进行处理的处理流程与上述TCU A的处理流程相同，但第二TCU不再发送交通应用类型和交通目标对象的第一交通信息给TCU A。
同理的，在交叉口碰撞预警应用类型中，移动的目标车辆作为交通目标对象，由目标车辆向TCU发送自己的当前位置和运动状态信息。交互覆盖区域包括该目标车辆行驶前方交叉口范围内、并且到该目标车辆特定距离内的区域。该区域内各种方向上轨迹可能与目标车辆交叉的其它车辆作为交通参与对象。目标车辆可以接收到作为交通参与对象的车辆的当前位置和运动状态信息后，在驶经该交叉口时警惕与其碰撞。
