초록

국내에서 운영되는 교통체계를 보다 안전하고 효율적으로 개선하기 위해 창원시를 대상으로 교통운영체계 선진화 사업이 시행되었다. 이 사업은 회전교차로 설치와 비보호좌회전 확대 등 10개의 단위사업이 포함되었고, 이에 대한 사업 전/후 효과 평가를 실시하였다. 본 논문에서는 회전교차로, 비보호좌회전, 좌회전감응신호 적용에 따른 정량적 및 정성적 평가결과를 분석하여 제시하였다. 정량적 분석결과로는 회전교차로 도입으로 평균 통행속도가 16.8% 향상되었으며, 비보호좌회전 확대 시행에 따른 평균 통행시간은 12.4% 감소하였으며, 제어지체는 41.6% 개선되었다. 좌회전 감응제어 운영으로 인한 평균 제어지체는 26.7% 감소한 것으로 분석되었다. 정성적 분석결과로는 회전교차로 도입으로 인한 만족도는 약 57.7%, 비보호 좌회전 확대 운영의 만족도는 약 60.3%로 분석되었다. 이와 같이 교통운영체계 선진화 사업에 대한 운영 효과가 크게 나타났고, 일반시민들의 만족도도 매우 높은 것을 파악되었다. 그러므로 선진화 사업의 적용 효과가 클 것으로 예상되는 지점을 파악하여 이를 확대 적용하는 것이 필요하다고 판단된다

In order to improve the safety and efficiency of traffic signal operation, several core projects of advanced transportation operating systems were implemented in Changwon City. This project included 10 units such as the expansion of roundabout, the permitted left-turn signal operation and the effectiveness of the projects was assessed using before and after studies. This paper presented the quantitative and qualitative evaluation results for three projects: roundabout, permitted left-turn signal operation, and left-turn actuated signal operation. From the analysis results, average travel speed was improved by 16.8% from the installation of roundabouts and average travel time and control delay were reduced by 12.4% and 41.6% respectively, from permitted left-turn operation. It was found that average control delay was reduced about 26.7% from left-turn actuated signal operation. In addition, more than 57.7% of the surveyed people was satisfied with the operational performance of the roundabout implemented. It is expected that the operational performance of traffic signal can be greatly improved by incorporating the proper projects of advanced transportation operating systems in other cities.
