The importance of easy wayfinding in complex urban settings has been recognized in spatial planning. Empirical measurement and explicit representation of wayfinding, however, have been limited in deciding spatial configurations. Our study proposed and tested an approach to improving wayfinding by incorporating spatial analysis of urban forms in the Guangdong-Hong Kong-Macau Great Bay Area in China. Wayfinding was measured by an indicator of intelligibility using spatial design network analysis. Urban spatial configurations were quantified using landscape metrics to describe the spatial layouts of local climate zones (LCZs) as standardized urban forms. The statistical analysis demonstrated the significant associations between urban spatial configurations and wayfinding. These findings suggested, to improve wayfinding, 1) dispersing LCZ 1 (compact high-rise) and LCZ 2 (compact mid-rise) and 2) agglomerating LCZ 3 (compact low-rise), LCZ 5 (open mid-rise), LCZ 6 (open low-rise), and LCZ 9 (sparsely built). To our knowledge, this study is the first to incorporate the LCZ classification system into the wayfinding field, clearly providing empirically-supported solutions for dispersing and agglomerating spatial configurations. Our findings also provide insights for human-centered spatial planning by spatial co-development at local, urban, and regional levels.
在空间规划中，人们已经认识到在复杂的城市环境中实现便捷寻路的重要性。然而，寻路的实证测量和明确表示在决定空间配置方面受到了限制。我们的研究提出并测试了一种方法，通过在中国粤港澳大湾区的城市形态的空间分析来改善寻路。寻路通过使用空间设计网络分析的可理解性指标来衡量。城市空间形态使用景观指标进行量化，以描述当地气候区 (LCZ) 的空间布局作为标准化城市形态。统计分析表明城市空间形态与寻路之间存在显著关联。这些发现表明，为了改善寻路，可以 1）分散 LCZ1（紧凑的高层建筑）和 LCZ2（紧凑的中层建筑），以及 2）聚集 LCZ3（紧凑的低层建筑）、LCZ5（开放的中层建筑）、LCZ6（开放的低层建筑）和 LCZ9（稀疏建筑）。据我们所知，这项研究首次将 LCZ 分类系统纳入寻路领域，为分散和聚集空间形态提供了明确的实证支持解决方案。我们的研究结果还为通过地方、城市和区域层面的空间共同发展提供了以人为本的空间规划的见解。
