交通运输信息融合功能模型

综述一般信息融合功能模型和交通运输信息融合应用的进展,指出这两个方面的联系和差异.针对交通运输应用的信息本质和功能特性,提出交通运输信息融合的一般定义,并建立了交通运输信息融合功能模型.模型对信源引入机器信息与认知信息的划分,提出了分属机器信息和认知信息两个层次的采集校验融合、状态特征融合、预测评估融合、规划设计融合和综合决策融合五级信息融合功能,提供了五级融合功能的三种应用模式,实现了不同交通运输应用功能与信息操作功能的衔接,与一般多传感器数据融合功能模型具有统一性.论文还以交通拥挤管理问题为例,给出了相应的信息融合功能模型.

Transportation Information Fusion Function Model

The achievements of the general information fusion function models and transportation applications were reviewed,and the involved relations and disjointedness were also pointed out.Aiming at the information essence and function characters of transportation applications,this paper defined a general concept of transportation information fusion and established a function model.The function model of transportation information fusion introduced the classification of the perception information and abiotic information for the information sources of transportation applications,designed five function levels of the information fusion,that is,collection and verification fusion,state and character fusion,prediction and evaluation fusion,plan and design fusion,and comprehensive decision-making fusion,all of which were fallen into two layers of perception information and abiotic information.Three applied patterns of the five function levels of the information fusion were presented at the same time.The proposed model joins information operating functions with different transportation applications,it bears coherence with the common function model of multisensor data fusion.At last,the corresponding function model of information fusion for traffic congestion management was presented as a practical example.
