Accessibility is fundamentally thought to be related to functional, economic, and social performances of cities and geographical systems and, therefore, constitutes an essential aspect for spatial planning. Previous studies focused on cities or metropolitan scales, often disregarding their position within regional and national systems, which can greatly affect their performance. Although accessibility at various spatial scales has been examined, the studies focused on accessibility patterns at different scales, with no reference to the level of accessibility of cities over local, regional, and national scales simultaneously, i.e. multiscale accessibility. This study aims to elucidate the multiscale accessibility level of individual cities and examine its relationship to urban performance in the urban system of Israel. Spatial accessibility was analyzed using the space syntax methodology for the entire national road network across multiple geographic scales—from the local to the national scale. Based on three distinct spatial accessibility systems identified, a unique multiscale accessibility profile was created for individual cities in Israel. Subsequently, each city’s multiscale accessibility profiles were examined against urban performance indicators determined from urban scaling theory. We found that the superiority of cities characterized by high accessibility level plays a role not only for a specific scale but also over scales and spatial systems. Moreover, most urban performance indicators related to the multiscale accessibility profiles of cities, while some multiscale accessibility profiles can be related to over- or under-performance of cities. The findings suggest that pervasive accessibility across spatial scales is inherently connected to urban performance and may indicate on the implementation and interpretation of accessibility. These findings may assist in various aspects of spatial planning at various scales.

可达性从根本上被认为与城市和地理系统的功能、经济和社会表现有关，因此是空间规划的一个重要方面。以前的研究侧重于城市或大都市规模，往往忽视它们在区域和国家系统中的位置，这会极大地影响它们的表现。虽然研究了不同空间尺度的可达性，但研究集中在不同尺度的可达性模式，没有同时参考城市在地方、区域和国家尺度上的可达性水平，即多尺度可达性。本研究旨在阐明各个城市的多尺度可达性水平，并检验其与以色列城市系统中城市绩效的关系。使用空间句法方法分析了跨多个地理尺度（从地方到国家尺度）的整个国家公路网的空间可达性。基于确定的三个不同的空间可达性系统，为以色列的各个城市创建了一个独特的多尺度可达性配置文件。随后，根据城市尺度理论确定的城市绩效指标，检查了每个城市的多尺度可达性概况。我们发现，以高可达性为特征的城市优势不仅在特定尺度上起作用，而且在尺度和空间系统上也起作用。此外，大多数城市绩效指标与城市的多尺度可达性概况相关，而一些多尺度可达性概况可能与城市的过度或欠佳绩效相关。研究结果表明，跨空间尺度的普遍可达性与城市绩效有着内在的联系，并可能表明可达性的实施和解释。这些发现可能有助于不同尺度的空间规划的各个方面。
