Abstract

In this paper, We propose a method which prevents severe traffic jam by controlling traffic signal by itself based on image-processed information and fuzzy logic. The detailed idea of this method is first to let a closed monitoring camera gather the number of cars which show the flow of traffic the designated roads which are commonly considered to have traffic. After executing the image processing method on each image gathered from the monitoring camera, this system determines the changing timing of traffic signal based on fuzzy logic. Also, this image processing method shows good performance in real road environment because the setup background image which used in this system is designed to be updated in real time. All of good points mentioned above would lead driver and users to cost efficient and time efficient results by preventing the increase of the number of traffic on road in advance with the automatic traffic signal controlling algorithm based on the fuzzy logic.

본 논문에서는 교차로에 설치된 카메라를 이용하여 각 도로로 유입 유출되는 교통량을 동시에 측정할 수 있도록 하였으며, 측정한 데이터를 퍼지논리에 적용하여 녹색 신호를 제어하는 시스템을 제안한다. 기존의 퍼지논리를 이용한 신호등 제어 시스템은 신호대기 중인 차량 숫자를 측정하여 기반 데이터로 사용하였으나, 본 논문에서는 영상처리를 이용하여 측정한 교차로 유입 차량 수를 퍼지논리의 기반 데이터로 사용하여 심각한 교통 정체가 일어나기 전에 이를 미연에 방지 할 수 있는 신호 제어로직을 고안한다. 본 논문에서 제안하는 교통신호 자동 제어로직을 활용하여 교통정체가 일어나기 전에 각 도로간 교통량을 조절함으로써 교통 정체로 발생하는 운전자의 시간 낭비 및 에너지 낭비를 예방한다.
