The widespread use of virtual audits has transformed the assessment urban design attributes by eliminating necessity for on-site visits. However, there remains a lack audit tools specifically designed evaluating parks in dense environments. This study aims to (1) adapt Audit Tool Activity-friendly Parks Dense Urban Areas (TAPS) into remote tool (R-TAPS), and (2) evaluate its reliability validity. Trained auditors used R-TAPS conduct (n = 53) Tokyo, with subset 25). Kappa statistics percent agreement assessed inter-rater reliability, intra-class correlation coefficient (ICC) verified convergent showed moderate almost perfect 89% items. Remote exhibited high positive (ICC 0.73). offers reliable virtually promote physical activity settings.
