어린이 보호구역 교차로 보행안전을 위한 시간가변형 공공디자인 연구 = Time-Variable Public Design for Pedestrian Safety at Intersections in School Zones

다국어 초록 (Multilingual Abstract)

This study proposes a time-variable public design that integrates the temporal rhythm of traffic flow and pedestrian behavior into the spatial configuration of school zones. Conventional school-zone facilities— such as static signage, surface colors, and fixed speed limits—remain limited in addressing time-dependent variations in mobility and visibility. To overcome these limitations, this research focuses on a 250-meter corridor surrounding Hansol Elementary School in Daegu, South Korea. Based on the data from the Korea Road Traffic Authority’s Traffic Access Analysis System (TAAS) statistics, the analysis identifies a dual- peak pattern of child pedestrian accidents, occurring predominantly during school commuting and rush hours. Drawing upon the principles of the Dutch Woonerf,—notably speed calming and spatial integration, —the study formulates three design guidelines: (G1) Speed Guidance, (G2) Pedestrian Safety, and (G3) Visual Readability. These principles are synthesized into a time-responsive spatial system titled “Safe O’Clock.” The design employs a clock-inspired rotating lever and pocket-type waiting bays that transform into three operational modes according to time: 0° (Open-Flow), 30° (Speed-Guidance), and 90° (Cross- Protection). Through this dynamic transition, the system reconciles conflicting demands of urban mobility: —absorbing pedestrian congestion during school hours, inducing voluntary deceleration in regular periods, and maintaining traffic efficiency at commuting peaks. Ultimately, Safe O’Clock reinterprets the conventional school-zone environment as an adaptive urban mechanism that responds to the rhythm of time. By translating behavioral periodicity into a tangible design logic, this study presents a pedestrian-safety model that transforms static regulatory infrastructure into a performative and time-sensitive spatial system.
