Optimal Design of the Signalized Intersection in Pusan Area using the Protected-Permissive Left-Turn Signal System

보호.비보호 혼용좌회전 신호체계를 고려한 부산지역 신호교차로의 최적설계에 관한 연구

The purpose in this study was to review the travel characteristics of the left-turn signal system on the signalized intersections under the study in Pusan area, construct the appropriate transportation systems under the different left-turn signal system : Protected Left-Turn signal system, Permissive Left-Turn signal system, and Protected-Permissive Left-Turn signal system based upon the travel characteristics reviewed, and finally suggest the optimal left-turn signal system which could reduce traffic delay and fuel consumption. and also improve traffic safety on the signalized intersections based upon the optimal transportation system constructed. Based upon the results, it was concluded that the Protected-Permissive Left-Turn signal system would be better and safer than the Permissive Left-Turn signal system in the aspects which could reduce decrease delay and fuel consumption, and simultaneously increase traffic safety on the signalized intersections, even if the optimal Permissive Left Turn signal system was found to be the best left-turn signal system in the aspects of the Measures of Effectiveness(MOE) on the intersections under the study.
