The present invention relates to an apparatus for predicting traffic speed and a method thereof, wherein traffic speed of the past may be inputted such that an in-depth auto-encoder may learn to output all the traffic speed of the past and traffic speed of the future, before the in-depth auto-encoder which has completely learned is used to predict the traffic speed of the future. Therefore, during the process in which the in-depth auto-encoder learns, even in the case in which the causal relationship between the traffic speed of the past and the traffic speed of the future is weak, in other words, even in the case in which the traffic speed of the future is significantly higher or lower than the traffic speed of the past, traffic speed may be predicted with high precision. To this end, the apparatus for predicting traffic speed and the method thereof according to the present invention may comprise: a control unit which allows the in-depth auto-encoder to learn in order to output all the traffic speed of the past and traffic speed of the future after the traffic speed of the past is inputted, and predicts the traffic speed of the future based on the in-depth auto-encoder which has completely learned; and a storage unit which stores the in-depth auto-encoder which has completely learned.

    본 발명은 교통속도 예측 장치 및 그 방법에 관한 것으로, 과거의 교통속도를 입력으로 하여 상기 과거의 교통속도와 미래의 교통속도를 모두 출력하도록 심층 오토인코더를 학습시키고, 상기 학습이 완료된 심층 오토인코더를 이용하여 미래의 교통속도를 예측함으로써, 상기 심층 오토인코더를 학습시키는 과정에서 과거의 교통속도와 미래의 교통속도 간의 인과 관계가 미약한 경우, 즉 과거의 교통속도에 비해 미래의 교통속도가 현저히 높거나 낮은 경우에도 정확도 높게 교통속도를 예측해 낼 수 있는 교통속도 예측 장치 및 그 방법을 제공하고자 한다. 이를 위하여, 본 발명은 과거의 교통속도를 입력으로 하여 상기 과거의 교통속도와 미래의 교통속도를 모두 출력하도록 심층 오토인코더를 학습시키고, 상기 학습이 완료된 심층 오토인코더에 기초하여 미래의 교통속도를 예측하는 제어부; 및 상기 학습이 완료된 심층 오토인코더를 저장하는 저장부를 포함할 수 있다.
