Abstract
Purpose: The purpose of this study is to derive improvements through user satisfaction analysis for the smart traffic safety system being applied to improve traffic safety. Method: A survey-based IPA analysis was used to derive system and service improvements for groups of drivers and pedestrians. Result: As a result of the analysis, both drivers and pedestrian groups showed that Quadrant 1(Keep up the Good Work) was 'Perception of risk information', and Quadrant 3(Low Priority) was 'Reliability of warning information'. On the other hand, 'AI display suitability', which was analyzed as Quadrant 1 (Keep up the Good Work) in the driver group, was found to be Quadrant 3(Low priority) in the pedestrian group. Conclusion: Satisfaction factors for smart pedestrian safety systems may vary depending on users, and it is judged that user-centered system construction and service provision are necessary.

연구목적: 본 연구는 교통안전 향상을 위해 적용중인 스마트 교통안전 시스템에 대하여 이용자의 만족도 분석을 통한 개선 사항을 도출하는데 목적이 있다. 연구방법: 설문조사 기반의 IPA 분석을 통해 운전자와 보행자 그룹의 시스템 및 서비스 개선 항목을 도출하였다. 연구결과: 분석 결과, 운전자와 보행자 그룹 모두 Quadrant 1(Keep up the Good Work)은 ‘위정정보 인지성’, Quadrant 3(Low priority)은 ‘주의정보의 정시성’으로 나타났다. 반면 운전자 그룹에서 Quadrant 1(Keep up the Good Work)로 분석된 ‘AI 디스플레이 적합성’이 보행자 그룹에서는 Quadrant 3(Low priority)으로 나타났다. 결론: 스마트 보행안전시스템은 이용자에 따라 만족 요인이 달라질 수 있으며, 이용자 중심의 시스템 구축 및 서비스 제공이 필요할 것으로 판단된다.
