The present invention relates to a system and method for controlling precision stop of a public transportation vehicle using an optical laser beam. According to the provided system and method for controlling precision stop of the public transportation vehicle, confirmation of a stop position and control of a stop of the vehicle is simply performed by using two optical laser beams, precision stop of the vehicle is possible without being affected by surrounding environment such as weather with a low cost compared to a preexisting precision stop method, and a position target of the vehicle is precisely displayed to a driver in advance to secure high accuracy and stability compared to the preexisting precision stop control method depending only on experience or skill of the driver. The system for controlling the precision stop comprises an optical unit, a collection unit, a calculation unit, and a control unit. 본 발명은 광학 레이저빔을 활용한 대중교통차량의 정위치 정차 제어 시스템 및 방법에 관한 것으로, 2개의 광학 레이저빔을 활용하여 간단하게 차량의 정차위치를 확인 및 정차 제어를 수행할 수 있고 기존 정위치 정차방식에 비해 저렴한 비용으로 날씨 등 주변환경에 큰 영향을 받지 않고 차량의 정위치 정차가 가능하며, 차량의 정위치 목표를 운전자에게 정밀하게 미리 표시해주어 기존 운전자의 경험이나 스킬 등에만 의존하는 정위치 정차 제어 방식에 비해 보다 높은 정확성 및 안정성을 확보할 수 있는 대중교통차량의 정위치 정차 제어 시스템 및 방법을 제공한다.
