The invention discloses an autonomous traffic system interoperation link evolution construction method, which comprises the following steps of: modeling traffic subjects, participating in traffic operation, of vehicles and roadside infrastructures in an autonomous traffic system as nodes; motion attributes of vehicles are represented through node attributes, traffic subjects can obtain information amount transmitted outwards through interoperation, supported interoperation communication systems and traffic subject autonomy level key elements, and the traffic subjects can be determined according to interoperation information satisfaction degree, communication distance between interoperation subjects, subject interoperation capacity and supported communication system factors. And calculating the probability of constructing a link between the design subjects, and constructing an interoperation link between the traffic subjects through a probability evolution mode. According to the method, the information transmission process of the interoperation process is comprehensively considered, the information age and other indexes are introduced to represent the effectiveness of the information, and a model basis can be laid for analyzing the time-varying trend and internal mechanism of the interoperation link state in the operation process of the autonomous traffic system.
本发明公开了一种自主式交通系统互操作链路演化构建方法,包括将自主式交通系统中的车辆、路侧基础设施参与交通运行的交通主体建模为节点,通过节点属性表征车辆的运动属性、交通主体可获取与通过互操作向外传递的信息量、支持的互操作通信制式和交通主体自主化水平关键要素,根据互操作的信息满足度、互操作主体间通信距离、主体互操作容量和支持的通信制式因素,计算设计主体间构建链路的概率,通过概率演化方式构建交通主体间的互操作链路。本发明例综合考虑了互操作过程的信息传递过程,引入了信息年龄等指标表征了信息的有效性,可以为分析自主式交通系统运行过程的互操作链路状态随时间变化的趋势与内在机理做好模型基础。
