A server for optimizing a traffic signal of a target intersection comprises: a traffic information collection unit which collects traffic information on a plurality of nearby intersections which exist within a preset distance range from a target intersection; an information conversion unit which inputs the traffic information about the plurality of nearby intersections into a pre-trained map learning-based shape conversion model and converts the information into valid data having a correlation with the target intersection; and a traffic signal optimization unit which derives a traffic signal of the target intersection by inputting the valid data into a pre-trained reinforcement learning-based signal optimization model. The shape conversion model can be trained using the reward of the signal optimization model as a label for the traffic information.

    대상 교차로에 대한 교통 신호를 최적화하는 서버는 대상 교차로로부터 기설정된 거리 범위 내에 존재하는 복수의 인근 교차로에 대한 교통 정보를 수집하는 교통 정보 수집부, 복수의 인근 교차로에 대한 교통 정보를 미리 학습된 지도학습 기반 형태변환 모델에 입력하여 대상 교차로와 상관관계를 갖는 유효 데이터로 변환하는 정보 변환부 및 유효 데이터를 미리 학습된 강화학습 기반 신호 최적화 모델에 입력하여 대상 교차로의 교통 신호를 도출하는 교통신호 최적화부를 포함하고, 형태변환 모델은 신호 최적화 모델의 리워드(Reward)를 교통 정보의 라벨로 이용하여 학습될 수 있다.
