초록
본 연구는 도로의 기상정보를 미리 예측하여 도로 이용자들에게 제공할 경우 발생되는 통행행태의 변화를 분석하고, 통행행태 변화에 영향을 주는 인자를 파악하고자 하였다. 분석을 위하여 1주일 간 온라인 기반 설문조사를 실시하여 총 600건의 유효 표본을 확보하였다. 확보된 표본은 구조방정식을 적용하여 통계적으로 분석하였다. 분석 결과, 현재 실시간 교통정보의 의존도가 높은 도로 이용자는 기상정보를 서비스할 경우, 우선적으로 통행수단을 변경할 가능성이 가장 높았으며, 그 다음으로 출발시간의 변경, 통행 포기, 경로 변경 순으로 나타났다. 또한 인적특성과 관련하여 도로이용자의 연평균 소득이 높을수록, 운전을 자주할수록, 연령이 높을수록 기상정보 기반 통행행태 변화 가능성이 높은 것으로 나타났다. 마지막으로 남성보다는 여성이 기상정보 기반 통행행태 변화 가능성이 높은 것으로 나타났다. 연구의 결과는 향후 예측된 기상정보의 활용도와 효과를 높이기 위한 서비스 전략 수립에 유용하게 활용될 것으로 기대된다.
Abstract
The objective of this study is to analyze the change in travel behavior when road users are provided with the weather forecast information and to identify its causal factors. A total of 600 samples were collected from web-based online surveys for one week and were analyzed statistically by using structural equation modeling (SEM). The results show that the road users highly dependent on real-time traffic information are likely to change their travel mode with highest priority. The next priorities are then given to the change of departure time, withdrawal of the plan for travel, and the change of the routes when the road users are provided with the weather forecast information. In addition, the road users with higher annual income, more frequent driving, and higher age have the higher tendency to change their travel behavior. Lastly, women are more likely to change their travel behavior than men. The results of this study are expected to contribute to the service strategies for utilizing and benefiting from the weather forecast information.
