标准范围

ISO 22951:2009涉及使用优先信号控制功能来帮助紧急车辆运行的系统。这种类型的系统由一个交通管理中心组成，在？车辆单元、路边通信单元和路边单元。公交车等公共交通工具也是优先信号控制服务的目标。标准化的范围包括与通信相关的消息集和数据字典，如下所示:在路边通信单元和每个车载单元之间，在路边通信单元和其他路边单元之间，在车载单元和路边单元之间。ISO 22951:2009仅涉及与优先信号控制相关的信息，而不涉及诸如现场情况的信息提供。由于需要根据各个城市和地区的情况来处理公共交通工具，因此消息和数据字典中与车辆的优先信号控制被视为一种选择。此外，标准化不取决于所使用的通信介质的类型。

ISO 22951:2009 relates to systems that use priority signal control functions to help emergency vehicles operate. This type of system is composed of a traffic management centre, in？vehicle units, roadside communication units, and roadside units. Public transport vehicles such as buses are also targeted to receive priority signal control service.The scope of standardization includes message sets and data dictionary related to the communications as follows:

• between a roadside communication unit and each in-vehicle unit,
• between a roadside communication unit and other roadside units,
• between in-vehicle units and roadside units.

ISO 22951:2009 concerns only information related to priority signal control and does not deal with information provision such as that of the situations at scenes. Since it is necessary to handle public transport vehicles in accordance with the conditions of individual cities and regions, the section in the messages and the data dictionary that are concerned with priority signal control for the vehicles are treated as an option. Furthermore, the standardization does not depend on the type of communication medium used.
