交通大数据关键技术研究

Research on Key Technologies of Traffic Big Data

作为数字化时代的新型资源,大数据成为驱动创新的重要因素,正在改变着人类社会的发展。大数据对科学研究、经济建设、社会发展和文化生活等各个领域正在产生革命性的影响。以交通数据资源和信息技术为支撑的城市交通决策和服务,是现代化城市交通的重要标志。近年来,随着城市交通信息化以及智慧城市建设的不断深入,各种数据的采集、汇聚已具规模,交通大数据的产生,是在大数据技术促进下城市交通信息化发展到一定阶段的必然结果。基于上海市交通信息化建设成就和数据基础,依托上海市科委《交通大数据应用关键技术研究与示范》课题研究成果,对交通大数据框架体系、基础理论、软硬件构建、实践应用等方面进行较为深入的研究和归纳,并对现代化城市交通管理决策和社会公众服务等方面的需求及发展做出展望。

As a novel resource in digital era, big data has been an important driving aspect of creativity, which is now changing our human society. Big data also brings the revolutionary effects to the areas including scientific research, economic construction, social development, culture and daily life, etc. Urban traffic decision and service supported by traffic data and information technology(IT) are important symbols in modern cities. With the development of traffic informationization and construction of smart city, types of traffic data have been collected and stored in certain scale recent years. Naturally, urban traffic big data rise from the developed traffic informationization in the background of big data technology. On the basis of the development of traffic informationization and stored data in Shanghai, this paper provides the research achievements which involve systematic frames, basic theories, software and hardware, practical applications, etc. It contains some achievements of the key projects from Shanghai Science & Technology Commission. And it also looks forward to the emergent requirements of the application direction of big data in traffic management, decision, and public service as well.
