Abstract

This study analyzes the factors effecting on pedestrian crossing behavior in the unsignalized intersection. Pedestrian crossing behavior is the results of mental stress defined as a combination of environment perception, avoiding accidents, halting collision, and instant crossing decision. It is necessary to make walkable intersection in cities through relieving this stress influenced by personality, traffic condition, and roadway environment. The purpose of study is empirically to examine the crossing behavior such as crossing satisfaction, crossing trial frequency and waiting time based on various factors effecting on crossing intersection by video and questionnaire survey. The $x^2$-test is applied to analyze the characteristics of crossing trial frequency according to each factor. Also, the hazard rate model is established to find the factors effecting on waiting time for crossing. Finally, the direct and indirect effects on the pedestrian crossing satisfaction are presented as the results of LISREL.

본 논문은 무신호 교차로에서 보행자의 횡단행태에 영향을 주는 요소를 분석하였다. 보행행태는 교차로 주변의 환경과 횡단의 기준, 안전에 대한 예견, 순간적인 판단 등이 복합적으로 작용하는 정신적 스트레스의 결과이다. 이러한 복합적 스트레스는 개인의 속성, 교통여건, 환경요인 등 다양한 요인에 의해 영향을 받는데, 이러한 영향요인을 파악하여 교차로를 운영하는데 있어 보행친화적인 환경을 조성할 필요가 있다. 현장과 설문 조사를 통하여 보행자가 비신호 교차로를 횡단하는데 있어서 영향을 주는 다양한 결정변수를 기초로 하여 횡단시도 횟수, 기다림 시간 및 보행횡단 만족도 등에 대한 횡단행태를 분석하는 것이 목적이다. 횡단시도횟수에 대한 각 요소별 특성을 분석하기 위해 $x^2$테스트를 실시하였으며 횡단을 위한 기다림 시간에 영향을 주는 요소를 분석하기 위해 위험률 모형을 구축하였다. 마지막으로 구조방정식을 적용하여 보행자의 보행 횡단 환경에 대한 만족도에 대한 직 간접 효과도 제시되었다.
