Development of an Environmental Design Evaluation Model to Prevent Lost Children in Complex Commercial Facilities

The purpose of this study is to develop an environmental design evaluation model that can evaluate the possibility of preventing lost children within complex commercial facilities. First, the concept of the "Line for Prevention of Breakaway", which adopted the defense line of CPTED, was newly defined. This concept was used as the standard for setting evaluation subjects and areas in this study. To score items within each evaluation area, a "Simple Additive Weighting Method" was applied; the applied weighted value was calculated by multiplying the weight of child loss risks obtained from the "Risk Matrix" and the weight of environmental elements of child loss prevention from each evaluation area. The evaluation scores from each area and item were estimated by multiplying the calculated weighted value with an average importance score from each environmental element of an evaluation item; the score was then reallocated based on the importance of each respective item. This evaluation model was verified in field investigations of four complex commercial facilities. A correlation analysis was used to compare each area's score and total scores with the rate of occurrence among lost children in these facilities. This evaluation model proved its significance to predict and prevent losing children in complex commercial facilities.
