Abstract
This study examines the evolution implications of neighborhood planning, focusing on modular and non-modular Neighborhood Planning Units (NPUs). Modular NPUs, such as those in Abu Dhabi, feature structured patterns that facilitate large-scale growth. Non-modular NPUs, like those in Dubai, have irregular street layouts lacking a clear planning language. This research analyzes 28 samples from 17 neighborhoods to evaluate the effectiveness of these configurations in promoting ordered, direct, and short routes to destinations within a 5- to 15-minute walk. Metrics used include Orientation Order (normalized entropy) and Pedestrian Route Directness (PRD). At 400 m, all neighborhoods had efficient, direct routes. However, at 1200 m, Abu Dhabi's modular neighborhoods provided more direct routes than Dubai's non-modular neighborhoods, which failed the directness test on all networks. While Orientation Order indicates network alignment, it did not correlate with directness at any tested scale; instead. block size and street density were the strongest predictors of route directness. In Abu Dhabi, even fragmented modular layouts achieved high Orientation Order and direct walking routes. Conversely, although some of Dubai's non-modular neighborhoods, had high Orientation Order, they struggled to provide direct walking routes. These results underscore the importance of modulatory and physical design in shaping planning policy.
期刊介绍:
Cities offers a comprehensive range of articles on all aspects of urban policy. It provides an international and interdisciplinary platform for the exchange of ideas and information between urban planners and policy makers from national and local government, non-government organizations, academia and consultancy. The primary aims of the journal are to analyse and assess past and present urban development and management as a reflection of effective, ineffective and non-existent planning policies; and the promotion of the implementation of appropriate urban policies in both the developed and the developing world.
