Abstract

Zones are the building blocks of urban analysis. Fields ranging from demographics to transport planning routinely use zones — spatially contiguous areal units that break-up continuous space into discrete chunks — as the foundation for diverse analysis techniques. Key methods such as origin-destination analysis and choropleth mapping rely on zones with appropriate sizes, shapes and coverage. However, existing zoning systems are sub-optimal in many urban analysis contexts, for three main reasons: 1) available administrative zoning systems are often based on somewhat arbitrary factors; 2) evidence-based zoning systems are often highly variable in size and shape, reducing their utility for inter-city comparison; and 3) official zoning systems are non-existent, not publicly available, or are too coarse, hindering urban analysis in many places, especially in low income nations. To tackle these three key issues we developed a flexible, open and scalable solution: the ClockBoard zoning system. ClockBoard consists of 12 segments divided by concentric rings of increasing distance, creating a consistent visual frame of reference for cities that is reminiscent of a clock and a dartboard. This paper outlines the design, potential uses and merits of the ClockBoard zoning system and discusses future avenues for research and development of new zoning systems based on the experience.

时钟板:用于城市分析的分区系统
分区是城市分析的组成部分。从人口统计到交通规划,各个领域都经常使用区域——将连续空间分解为离散块的空间连续区域单元——作为各种分析技术的基础。始发地-目的地分析和choropleth映射等关键方法依赖于具有适当大小、形状和覆盖范围的区域。然而,在许多城市分析背景下,现有的分区系统是次优的,主要原因有三:1)现有的行政分区系统往往基于一些武断的因素;2) 基于证据的分区系统在规模和形状上往往高度可变,降低了其在城市间比较中的效用;3)官方分区系统不存在、不公开或过于粗糙,阻碍了许多地方的城市分析,尤其是在低收入国家。为了解决这三个关键问题,我们开发了一个灵活、开放和可扩展的解决方案:时钟板分区系统。ClockBoard由12个部分组成,由距离不断增加的同心环划分,为城市创造了一个一致的视觉参考框架,让人想起时钟和飞镖。本文概述了ClockBoard分区系统的设计、潜在用途和优点,并根据经验讨论了未来研究和开发新分区系统的途径。
