Abstract

For the purpose of the research, it is analyze the influence traffic Signal Progression on a CBD by expansion of Permissive Left-Turn on the advanced traffic management system program compared with traffic response control For this, divided a average distance between intersections, a traffic network on five district in four city. As the result, Volume of the traffic management system on a advanced traffic management system program compared with traffic response control is effective in traffic signal cycle 160sec 286car per lane, in 140sec 308car, 120sec 264car. As well, for a traffic network as the length of a traffic network 2.0~3.0km, under 2.0km, all of traffic signal cycle(160sec, 140sec, 120sec) a passing band and stop is more effective. But the traffic management system on traffic response control compared with the traffic management system on a advanced traffic management system program is effective in the length of a traffic network over 5.0km. For the efficiency of traffic signal system manage, it should be runned the traffic management system on traffic response control in addition to the traffic management system on a advanced traffic management system program on CBD. As the result of simulation the business in chungju-si, the travel speed of the traffic management system on a advanced traffic management system program is 41.2km/h and the travel speed of traffic response control is 37.5km/h. Therefore, it should be runned per length of a traffic network the traffic management system on traffic response control in addition to the traffic management system on a advanced traffic management system program on CBD.

본 교차로에 각 방향별 이동류의 상충해소를 위한 목적으로 도입된 교통신호제어는 차량증가에 따라 여러 교차로를 연계하여 정지와 지체시간을 최소화하는 간선도로 제어 목적으로 바뀌었고 이를 위해 교통신호운영 효율화를 위한 다양한 방법이 제시되고 있다. 본 연구는 도심 가로축 연동체계를 교통운영체계 선진화 방안에서 제시하고 있는 비보호좌회전확대로 운영되는 선직진 후좌회전 체계와 기존 실시간 대응제어 신호운영체계를 비교 분석하였으며, 비교 분석을 위해 4개시 5개 지역을 선정 평균 교차로 간격, 연동 가로축 거리 등을 구분하였다. 그 결과 교통운영체계 선진화 방안 신호운영체계의 교통처리용량은 실시간 대응제어 신호운영체계의 교통처리용량 보다 주기 160초 때 차로 당 286대, 140초 경우 308대, 120초 경우 264대가 증가하여 1차로 도로확장을 한 만큼의 효과가 있는 것으로 나타났다. 또한 가로축 연동에 대해서도 가로축 길이 2.0~3.0km, 2.0km미만에서 분석 주기(160초, 140초, 120초) 모두에서 연동밴드 폭이나 정지횟수에서 효과가 있는 것으로 나타났다.
