Background: The smart city approach is one of the most widely implemented urban development frameworks to solve the challenges brought about by urbanization. While the smart city approach has been evaluated across several urban dimensions. However, the extent to which the key performance indicators (KPI) assess security and safety dimensions is unknown. This protocol presents a systematic review of current KPIs to fill this gap. Objectives: This protocol details the work plan for a systematic review of KPI for public safety smartness designed to provide a comprehensive summary and their limitations in the scientific literature. Particularly, the study seeks to critically review the applicability of current public safety KPI to the Andalusian context. Specifically, the systematic review aims to synthesize: (RQ1) What indicators have been designed and used to measure urban public safety smartness; (RQ2) Within which smart city dimensions have the KPI been located; and (RQ3) How are the KPI defined and measured? Design: This systematic review follows the PRISMA statement. Five databases are searched for thematically relevant studies published in English or in Spanish. Studies included peer?reviewed publications, books, book chapters, conference papers, government and company documents, technical reports and doctoral theses. After the initial search, a pilot study was conducted on a sample of the total number of titles identified through the databases searches. After acceptable inter-rater reliability was reached among the three coders, screening of abstracts was carried out by the first author. Next, full-text screening of documents will determine the final sample. Finally, data will be extracted from the final selection of documents.Security and Global Affair
