Introduction
Dr. Wu's research spans the interdisciplinary fields of architecture, geographic information science, and urban informatics, specifically focusing on integrating data with emerging quantitative methods to understand urban forms and their relationship with urban activities. This approach provides decision support for urban design and renewal.

Polycentric urban development is gaining momentum in both scholarly research and real-life practice. This brings new demand for planning support systems to simulate and analyse the urban spatial structure in terms of polycentricity under various urban policy scenarios. With the help of emerging urban data, urban simulation techniques, and network s...
Streets are a crucial part of the built environment, and their layouts, the street patterns, are widely researched and contribute to a quantitative understanding of urban morphology. However, traditional street pattern analysis only considers a few broadly defined characteristics. It uses administrative boundaries and grids as units of analysis tha...
This study introduces a machine learning-based framework for mapping street patterns in urban morphology, offering an objective, scalable approach that transcends traditional methodologies. Focusing on six diverse cities, the research employed supervised machine learning to classify street networks into gridiron, organic, hybrid, and cul-de-sac pat...
Master plans are pivotal in strategising urban development, dictating land use, building height, and development intensity. These plans influence the spatial arrangement of urban infrastructure and activities, shaping the morphological and dynamic urban spatial structure. This study evaluates Singapore’s master plan’s effect on urban spatial struct...
Urban design and planning practices traditionally use a survey-analysis-design paradigm. Data are collected through site surveys followed by comprehensive analysis to generate knowledge for a context-specific design scheme with different professionals working on varying levels of detail. Nowadays, the practice has entered the age of digitalisation...
Urban morphology profoundly influences city planning and experiences significant transformations as cities evolve. This paper investigates paradigm shifts in block-level planning through a case study of Singapore, a city celebrated for its precision in urban planning and swift transformation. Integrating urban morphology theories with empirical dat...
Street patterns are planar street layouts in a given urban area, which serve as tools for researchers and urban planners to comprehend the structure of urban environments. Nonetheless, the task of mapping street patterns for extensive inter-city studies remains daunting due to the lack of consistency in manual identification methods. With recent te...
The automatic identification of urban functional regions (UFRs) is crucial for urban planning and management. A key issue involved in URF classification is to properly determine the basic functional units, for which popular practices are usually based upon existing land use boundaries or road networks. Such practices suffer from the unavailability...
