【摘要】：綜合智能交通系統(tǒng),能夠提高交通基礎(chǔ)設(shè)施的有效利用率,緩解我國日益突出的交通擁堵問題.數(shù)據(jù)是綜合智能交通系統(tǒng)運(yùn)行的核心,綜合智能交通系統(tǒng)的有效運(yùn)行離不開大量多源實(shí)時(shí)基礎(chǔ)交通數(shù)據(jù)的支持.如何及時(shí)并有效地對(duì)綜合智能交通系統(tǒng)所采集的多源異構(gòu)數(shù)據(jù)進(jìn)行有效集成,是目前智能交通系統(tǒng)研究領(lǐng)域亟待解決的基礎(chǔ)問題之一.以云南省"七彩云南智慧出行云服務(wù)平臺(tái)"的建設(shè)過程為基礎(chǔ),介紹了一種在面向綜合智能交通系統(tǒng)的多源異構(gòu)數(shù)據(jù)集成框架,該框架是一種基于元數(shù)據(jù)的異構(gòu)數(shù)據(jù)集成框架.通過該框架,能夠?qū)C合智能交通系統(tǒng)中的靜態(tài)結(jié)構(gòu)化異構(gòu)數(shù)據(jù)和動(dòng)態(tài)非結(jié)構(gòu)化異構(gòu)數(shù)據(jù)進(jìn)行及時(shí)有效的數(shù)據(jù)集成.
[Abstract]:Integrated Intelligent Transportation system (its) can improve the effective utilization of traffic infrastructure and alleviate the increasingly prominent traffic congestion in China. Data is the core of the integrated intelligent transportation system. The effective operation of the integrated intelligent transportation system can not be separated from the support of a large number of multi-source real-time traffic data. How to effectively integrate the heterogeneous and multi-source data collected by the Integrated Intelligent Transportation system (its) is one of the basic problems to be solved in the field of Intelligent Transportation system (its). Based on the construction process of Yunnan colorful Yunnan Intelligent Travel Cloud Service platform, this paper introduces a multi-source heterogeneous data integration framework for integrated intelligent transportation system, which is a meta-data-based heterogeneous data integration framework. Through this framework, the static structured heterogeneous data and dynamic unstructured heterogeneous data in the integrated intelligent transportation system can be integrated in a timely and effective manner.
