Big Data Analytics in Intelligent Transportation Systems: A Survey

TLDR

Big data is a growing research focus in intelligent transportation systems, which generate large volumes of data and are increasingly studied worldwide. This paper reviews the history and characteristics of big data and ITS and discusses open challenges in using big data analytics in ITS. The authors present a framework for conducting big data analytics in ITS, summarizing data sources, collection methods, analytics techniques, platforms, and application categories, and illustrate it with case studies on traffic accidents, flow prediction, public transport planning, personal routing, rail management, and asset maintenance. The produced big data will have profound impacts on the design and application of intelligent transportation systems, making ITS safer, more efficient, and profitable.

Abstract

Big data is becoming a research focus in intelligent transportation systems (ITS), which can be seen in many projects around the world. Intelligent transportation systems will produce a large amount of data. The produced big data will have profound impacts on the design and application of intelligent transportation systems, which makes ITS safer, more efficient, and profitable. Studying big data analytics in ITS is a flourishing field. This paper first reviews the history and characteristics of big data and intelligent transportation systems. The framework of conducting big data analytics in ITS is discussed next, where the data source and collection methods, data analytics methods and platforms, and big data analytics application categories are summarized. Several case studies of big data analytics applications in intelligent transportation systems, including road traffic accidents analysis, road traffic flow prediction, public transportation service plan, personal travel route plan, rail transportation management and control, and assets maintenance are introduced. Finally, this paper discusses some open challenges of using big data analytics in ITS.
