초록

활동기반 모형은 개개인의 다양한 일상 활동을 교통계획의 의사결정단위로 파악하고, 인간의 활동으로 인해 파생된 통행을 분석한다. 즉, 동일한 활동패턴 집단의 유형의 사회경제적, 상황적 특성에 따라 어떤 활동을 수행할 것인지를 결정하고 활동수행주체의 활동시간, 공간의 이동, 교통수단을 선택하는 행위에 대한 예측을 수행한다. 통행은 개인과 다른 사람들이 참여하여 이루어지는 복합적인 의사결정 과정으로 간주되기 때문에 이를 통한 활동기반모형은 교통수요 예측에 있어 보다 효율적이면서 현실에 부합한 수요추정을 수행 할 수 있다. 이러한 과정에서 개인의 하루 활동유형을 선택하는 과정은 매우 중요하며, 이에 따라 활동기반 모형의 통행이 발생된다고 할 수 있다. 본 연구에서는 개인의 활동유형 선택에 영향을 주는 요인을 파악하고, 개개인의 특성에 따라 활동유형 선택행태를 분석하였다. 먼저 통행사슬 유형과 활동목적을 검토하여 활동유형을 분류하고, 활동유형선택에 영향을 미치는 개개인의 사회경제적 특성변수를 도출하였다. 다음으로 활동유형별 다항 로지스틱 회귀분석 모형을 구축하여, 활동수행주체의 복합적 특성에 따라 선호되는 활동패턴에 대한 분석을 수행하였다. 결론적으로 활동유형의 선택은 활동수행주체의 복합적인 특성에 의존하며, 장래 활동기반 교통수요 예측에 있어 개인의 복합적인 특성이 활동기반 모형의 활동스케줄 결정 과정에서 고려되어야 함을 시사하고 있다.

Activity-based models analyze individuals' various daily activities that are identified as a decision-making unit for transportation planning. In other words, it is the model that determines the types of activities according to the social, economic and situational characteristics of the groups with the same activity patterns and predicts individuals' activity time, distance, spatial movement and transportation mode. The activity-based model is a method of estimating more efficient and realistic demand in transportation forecasting because traffic is regarded as a complex decision-making process that an individual and other people participate in. In this paper, we grasp the factors affecting choice behavior of activity pattern and analyze choice behavior of activity pattern based on multi-dimensional characteristic of each person. First, we classify activity types of reviewing the trip chain and activity purpose. Next, we identified preferable activity types using complicated characteristics of main agent of activity. We concluded that choice behavior of activity pattern is dependent on complex characteristics of each agent, and further multi-dimensional characteristics of each person are affected over the whole decision process of activity schedule.
