The planning of green-blue spaces (GBSs) requires considering the pedestrian needs in their walking routes for improving experience. Incorporating quantitative spatial characteristics movement is essential pedestrian-friendly urban planning, which however received insufficient attention. Based on space syntax theory, this study provided three indicators – accessibility, visibility, and intelligibility to demonstrate physical access, visual cognition, respectively, movement. Measuring these indicators, exemplified GBSs using Guangzhou, China as a case study. Spatial design network analysis was used quantify heterogeneous values each GBS throughout city. Moreover, we principal component identify leading based weightings then calculate scores compare aspects GBSs. measurements were averaged across administrative districts evaluating city-scale findings showed that central most accessible visible but least intelligible. In contrast, overall city greatest visibility least. Furthermore, intelligibility, more important factor than accessibility should be particularly emphasized future Pedestrians from Guangzhou satisfied with experience, terms accessing to, viewing, cognizing 'Yuexiu', 'Huadu', 'Nansha' found key places where improved needed improve pedestrian-friendliness summary, not only demonstrated human-scale evaluation framework human experience also empirical evidence building at scale.
