Abstract
Objective: This study aims to develop a pedestrian safety assessment model for underground parking facilities that comprehensively measure the pedestrian safety level of an underground parking facility.BRBRBackground: Although underground parking spaces have many potential risks that can cause pedestrian accidents, assessment frameworks that enable to comprehensively measure and monitor the risk levels of underground parking facilities have not been widely discussed in the literature. In this regard, it is necessary to develop a safety assessment framework that can objectively and quantitatively capture the safety level in an underground parking facility.BRBRMethod: 381 indicators that are associated with general pedestrian safety were extracted from the extant literature first. Then, these indicators were streamlined and standardized based on the importance of each indicator. Finally, a total of ten identified major indicators with sub-indicators and three safety factors categorizing these indicators were derived as a basis of a safety assessment framework. A weighted average scoring system using Analytic Hierarchy Process (AHP) was employed for the indicators measured in a Likert scale and their associated factors to quantify the overall safety level. The proposed framework was applied to a case study of a Korean university.BRBRResults: The results showed the overall safety level of the undergraduate parking facility at the university is in a range of
