时空数据及其在智慧交通中应用

Spatiotemporal Data and its Applications in Smart Transportation

地理数据在交通领域有广泛的应用,传感网、物联网、社交网络等技术迅猛发展,交通领域进入了真正的大数据时代,时空数据是智慧交通中应用最广泛的数据。将时空数据分为地理数据和时空大数据,首先分析了地理数据、时空大数据和智慧交通系统的基本特征,总结归纳了时空大数据在智慧交通中应用。为测绘地理信息领域时空数据的生产、处理与分析,时空数据在交通分析、交通基础设施规划建设、交通运营管理与运输组织、公众信息服务、交通安全方面的应用提供参考。

With the rapid development of sensor network,internet of things,social network and other technologies,geographic data has been widely applied in the field of transportation.Transportation has entered the real big data era,spatiotemporal data is the most widely used data in smart transportation.Spatiotemporal data is divided into geographic data and spatiotemporal big data in the paper.The basic characteristics of geographical data,spatiotemporal big data and smart transportation system are analyzed.Then the application of spatiotemporal big data in smart transportation is summarized.For the production,processing and analysis in the field of surveying and mapping geographic information,spatiotemporal data can provide reference in traffic analysis,transportation infrastructure planning and construction,transportation operation management and transportation organization,public information services,and traffic safety.
