Abstract

By securing golden time, this study analyzed the effects of an emergency vehicle priority system in Cheongju, North Chungcheong province. Until the scene of a fire is reached, severe obstacles in the street, such as traffic congestion, cars coming forward, non-cooperative vehicles etc., are significant. To solve these problems of road obstacles, it is essential to adopt an emergency vehicle priority system. From April 2017 to June 2018 (1 year and 2 months, 426 days), the dispatch time and date, fire truck moving distance and required time, traffic signal control section and pass time, and shortening time, were measured. This study selected 140 cases consisting of five heavy traffic and frequent dispatch routes out of 293 cases. The effects of the emergency vehicle priority system were excellent. Overall, it took 3 min 3 s to pass 1 km on an uncontrolled traffic signal section. On the other hand, it took 1 min 23 s to pass 1 km on the same section that was controlled. The shortening time to pass 1 km was 1 min 40 s, showing a 45.4% reduction. This means that the 15 min driving time can be reduced to 6 min and 49 s. From this result, an emergency vehicle priority system should be implemented nationwide as soon as possible.

골든타임의 확보 방안으로 충북 청주시에서 시행하는 긴급차 우선신호체계 운영 결과를 분석하였다. 화재현장에 도착하기까지 도로상의 극심한 교통정체, 긴급차 앞으로 끼어드는 차량, 긴급차 길터주기에 비협조적인 차량 등 출동 중에 나타나는 장애요인들은 심각한 상태이다. 이와 같은 도로상의 장애문제를 해결하기 위하여 긴급차 우선신호체계를 도입하는 것은 반드시 필요하다. 2017년 4월부터 2018년 6월까지(1년 2개월, 426일) 출동시간과 날짜, 긴급차의 이동거리와 시간, 교통신호 통제구간과 통과시간, 단축시간 등을 측정하였다. 293개의 출동회수 중 교통이 혼잡하고 출동이 잦은 5개의 구간에서 140개의 선택하였다. 교통신호시스템을 통제한 결과는 놀라웠다. 총괄적으로 신호를 통제하지 않을 때에는 1 km를 주행하는데 3 min 3 s가 결렸지만 신호를 통제하여 긴급차를 우선통행하도록 하는 경우에는 1 km를 1 min 23 s에 주행하여 처음의 45.4% 밖에 걸리지 않았다. 즉 15 min 걸리던 주행시간을 6 min 49 s로 줄인 것이다. 이러한 결과를 볼 때 긴급차 우선신호시스템은 가능한 한 빨리 전국적으로 실시하여야 할 것이다.
