보행자의 안전과 보행지체 향상을 위하여 대각선 횡단보도의 설치가 증가하고 있다. 기존 연구는 대각선 횡단보도의 설치 기준을 판별할 때 차량지체만을 주요 변수로 설정한 경우가 많았다. 이러한 설치기준은 대각선 횡단보도 설치의 궁극적 목적인 보행자의 안전과 보행지체 개선 측면을 측정할 수 없다는 한계가 있다. 본 연구는 보행지체, 차대사람 상충횟수, 차량지체, 차대차 상충횟수 개선율을 함께 고려하는 MOE를 구성하여 대각선 횡단보도 설치 전후의 효과를 시뮬레이션 분석했다. 분석 결과, 대각선 횡단보도의 설치는 보행지체 감소 효과와 차대사람 상충횟수 감소에 따른 보행자 안전성 향상에 기여한다는 것을 확인할 수 있었다. 본 연구에서 제시한 MOE는 변동폭이 큰 상충횟수와 차량지체에 주로 영향을 받았으며, 일정 수준 이상의 차량 통행량에서는 운영이 지양되는 구간도 판별하였다. 본 연구에서 제시된 대각선 횡단보도의 설치기준은 보행자와 차량 운전자를 모두 고려하고 대각선 횡단보도 설치의 목적에 부합하는 기준을 제시했다는 점에서 의의가 있다.
In order to improve the pedestrian safety and pedestrian delay, the usage of scramble crossings has been increasing over the past few years. However, previous studies that deal with Measure of Effectiveness (MOE) for scramble crossings tend not to consider factors such as pedestrian safety and delays. These installation criteria are limited since they cannot measure the improvement perspective of pedestrian safety and pedestrian delay, which are ultimate goals of scramble crossing. The following paper proposes an improved MOE that considers the following factors: delays in pedestrian crossing time, delays in driving, number of vehicle-to-vehicle conflicts, and number of vehicle-to-pedestrian conflicts. Simulations of pre- and post-installation of scramble crossings on an intersection were used to measure the previously mentioned factors. Analysis results revealed that the installation of scramble crossings contributed to the decrease of pedestrian delays and the decrease of number of conflicts. The MOE was highly influenced by the frequency of conflicts (vehicle-to-vehicle, vehicle-to-pedestrian). From the analysis, due to the high number of vehicle-to- vehicle conflicts and high levels of congestion, identifying conditions that do not operate the scramble crossing was possible. Thus, the proposed MOE has been proven to be an effective installation criterion as it considers factors of pedestrians and those of vehicles.
