The present invention relates to a system for forecasting the traffic condition pattern by an analysis of traffic data. The forecasting system thereof according to Example 1 of the present invention comprises a queue length estimation unit, which receives from a cloud server the information about vehicle passage time and speed of a first intersection or a second intersection, measured by a first beacon installed in the first intersection or a second beacon installed in the second intersection adjacent to the first intersection, and from the vehicle passage time and speed information of the first intersection or the second intersection, estimates the queue length of vehicles that entered the first intersection but did not pass the second intersection; a traffic estimation unit that uses the estimated queue length to calculate the traffic density by road segment between the first intersection and the second intersection, to thereby estimate the traffic; a traffic correction unit that corrects the estimated traffic data based on the historical data by road segment stored in the cloud server; and a traffic condition information calculation unit that applies data mining and pattern matching method to the corrected traffic data, to thereby calculate the traffic condition pattern and the traffic turning rate by time period and road segment.
A system for forecasting the traffic condition pattern by an analysis of traffic data, which comprises a vehicle queue length estimation unit, which receives the information about vehicle passage time and speed of a first intersection or a second intersection measured by a first beacon installed in the first intersection or a second beacon installed in the second intersection adjacent to the first intersection from a cloud server, and from the vehicle passage time and speed information of the first intersection or the second intersection, estimates the queue length of vehicles that entered the first intersection but did not pass the second intersection;
A method for forecasting the traffic condition pattern using a system for forecasting the traffic condition pattern by an analysis of traffic data, which comprises a step of a first beacon installed in a first intersection, or a second beacon installed in a second intersection adjacent to the first intersection, measuring the information about vehicle passage time and speed of the first intersection or the second intersection, and transmitting the information to a cloud server;
