Abstract
Massive traffic data is produced constantly every day, causing problems in data integration, massive storage, high performance processing when applying conventional data management approaches. We propose a cloud computing based system H-TDMS (Hadoop based Traffic Data Management System) to capture, manage and process the traffic big data. H-TDMS designs a configurable tool for data integration, a scalable data scheme for data storage, a secondary index for fast search query, a computing framework for data analysis, and a web-based user-interface with data visualization service for user interaction. Experiments on actual traffic data show that H-TDMS achieves considerable performance in traffic big data management.
