Abstract

In most public transportation related master plans, decisions for investment priorities are initially made by facilities with lower installation rates or lower satisfaction (performance) levels. In general, the decisions are made without conducting importance factor analysis. In this study, a combined method of importance-performance analysis (IPA) model for bus users related in travel time is proposed by using Structural Equation Model (SEM). The results of the IPA for Metropolitan users show that the categories need improvement are number of bus stops, number of intersections, headways, waiting times for boarding and traffic signal operations in order. On the other hand, Non-Metropolitan uses show that the categories need improvement are traffic signal operations, waiting times for boarding, headways, bus exclusive lanes and number of intersections that is in reverse order to Metropolitan users.

현재 수립된 대부분의 대중교통관련 계획에서는 투자우선순위를 결정함에 있어 중요도(importance) 분석 없이 시설물 조사와 설문 조사를 통해 시설물에 대한 설치율과 만족도(performance)가 낮은 항목을 우선적으로 고려하여 투자순위를 결정하고 있다. 본 연구에서는 구조방정식모형(SEM: Structural Equation Model)을 활용하여 버스 이용자의 통행시간에 대한 중요도와 만족도를 동시에 고려할 수 있는 중요도-만족도 분석(IPA: Importance-Performance Analysis) 기법을 제시하였다. 수도권과 비수도권을 대상으로 버스이용자에 대한 IPA 분석을 실시한 결과 수도권의 경우 우선적인 개선이 필요한 항목으로는 버스정차횟수, 교차로수, 배차간격, 승차대기시간 및 신호체계 순서로 분석되었고, 비수도권의 경우 수도권의 역순인 신호체계, 승차대기시간, 배차간격, 버스전용차로 및 교차로수 순서로 분석되었다.
