Abstract

This study aims to evaluate the performance of Hook-turn operation with various sizes of bicycle waiting zone(WZ) and to determine the optimal size of bicycle WZ under various traffic and control circumstances. An extensive simulation study was performed to examine bicycle and vehicle delay trends for given experimental design. Results showed that vehicle delay was insensitive to the size of waiting zone, but bicycle delay was reduced as the size of waiting zone increased in general. The delay performance indicated a similar trend between with RTOR and without RTOR operation, but vehicle delay slightly increased and bicycle delay slightly decreased without RTOR. Regarding to optimal waiting zone size, 6 WZ was recommended for general conditions with RTOR, but 9 WZ was recommended when bicycle left-turn volume was greater than 120 v/h. 6 WZ was recommended for general conditions without RTOR, but 12 WZ was recommended when bicycle left-turn volume was greater than 90 v/h.

본 연구는 자전거 대기공간 크기의 변화에 따른 Hook-Turn 방식의 운영효과를 파악하고, 신호교차로를 운영 시 요구되는 적정한 대기공간의 크기를 다양한 교통상황에서 평가하여 제공하는 목적으로 수행하였다. 이를 위하여 시뮬레이션 기법을 이용하여 다양한 차량조건, 자전거 교통량, RTOR 우회전 통행방식을 고려하여 자전거 및 차량 지체의 변화를 평가하였다. 평가 결과, 일반적으로 차량 지체는 자전거 대기공간에 큰 영향이 없으나, 자전거 지체는 대기공간이 증가함에 따라 감소되었다. 그리고 RTOR 적용시와 비적용시의 차량과 자전거 지체의 패턴은 유사하였지만, RTOR 비적용시 차량지체는 약간 증가하였고, 자전거 지체는 감소하였다. 이러한 효과 차이는 우회전 교통향이 크게 증가하면 크게 변할 것으로 예상된다. RTOR 적용시에는 6대의 대기공간이 필요하나, 자전거 좌회전 교통량이 120대보다 많은 경우 9대의 대기공간을 제공하는 것이 권장된다. RTOR 비적용시에는 6대의 대기공간이 필요하나, 자전거 좌회전 교통량이 90대보다 많은 경우 12대의 대기공간을 제공하는 것이 권장된다.
