(English Abstract)
ITS (Intelligent transport system) offers a wide range of traffic information and services by integrating the IT-related high technology with transportation and facilities. By collecting road traffic data from various data sources such as road sensors and mobile phones, an ITS monitors the current road status of the urban area. However, when huge volumes of traffic data are collected, it is not efficient for a user to query road traffic data for finding similar traffic situation. To overcome this limitation, in this paper we propose a road traffic data query system which uses the MapReduce functionalities of NoSQL database. Raw road traffic data are converted into traffic matrices and stored into a MongoDB document database. Also, by computing a singluar value decomposition (SVD) from transformed traffic matrices and using the SVD, it is possible to query the road traffic data efficiently. We evaluate the efficiency of the proposed system by using the real road traffic data obtained from Busan metropolitan city.
