A server optimizing traffic signals of a target intersection may comprise: an input unit which receives information on a target intersection among a plurality of intersections; a traffic information collecting unit which collects traffic information on a plurality of neighboring intersections existing within a preset distance range from the target intersection; a speed calculation unit which based on the traffic information on a plurality of neighboring intersections, calculates a plurality of speed prediction rates of each neighboring intersection for various periods through a road speed prediction model; a correlation intersection selecting unit which based on a plurality of calculated speed prediction rates of each neighboring intersection, selects a major neighboring intersection having a correlation with the target intersection; a traffic information prediction unit which based on a plurality of speed prediction rates of the major neighboring intersection, predicts a speed in the target intersection; and a traffic signal optimizing unit which based on the predicted speed in the target intersection, controls a traffic signal of the target signal. Accordingly, the present invention can improve the accuracy of traffic signal control over the target intersection.

    대상 교차로의 교통 신호를 최적화하는 서버는 복수의 교차로 중 대상 교차로에 대한 정보를 입력받는 입력부, 대상 교차로로부터 기설정된 거리 범위 내에 존재하는 복수의 인근 교차로에 대한 교통 정보를 수집하는 교통 정보 수집부, 복수의 인근 교차로에 대한 교통 정보에 기초하여 도로 속도 예측 모델을 통해 다양한 기간에 대한 각 인근 교차로의 복수의 속도 예측률을 산출하는 속도 산출부, 산출된 각 인근 교차로의 복수의 속도 예측률에 기초하여 대상 교차로와 상관관계를 갖는 주요 인근 교차로를 선정하는 상관관계 교차로 선정부, 주요 인근 교차로의 복수의 속도 예측률에 기초하여 대상 교차로의 속도를 예측하는 교통 정보 예측부 및 예측된 대상 교차로의 속도에 기초하여 대상 교차로의 교통 신호를 제어하는 교통신호 최적화부를 포함할 수 있다.
