(English Abstract)
In this paper, we propose a framework for detecting traffic flow data from CCTV video and analyzing causality between traffic congestion. We track vehicles from CCTV video to detect traffic flow. The loss data which is occurring becauase of by the lack of CCTV cameras is supplemented from GPS average speed data. We model the traffic network by detected traffic flow data and road network information. We calculate causality between congestions with traffic network model and the Granger causality test.
