Research Trends in Housing Shortages and Road Network Efficiency ‎Within ‎Urban Master Planning: A Bibliometric Review

Abstract

Urban inadequacies, such as the lack of proper housing systems and the declining road network efficiency, represent significant challenges for cities globally, particularly in developing nations. These shortcomings exert a negative effect on social equity, economic development, and urban sustainability, directly impacting the quality of life of urban inhabitants. Given that housing is an essential human need and road networks are fundamental for mobility, commerce, and social interaction, addressing these deficiencies is critical. Consequently, this study investigates these issues by incorporating planning strategies that integrate housing units and transportation systems into urban master plans. This research provides a comprehensive review of the pertinent literature regarding housing shortages, urban deficit analysis, and urban planning trends. Using the Scopus database for the period from 2001 to 2025, this study performs a bibliometric analysis supported by VOSviewer to demonstrate research trends, collaboration networks, and thematic clusters. Furthermore, the paper evaluates various methodological tools utilized in these studies, specifically Geographic Information Systems (GIS), Multi-Criteria Decision Analysis (MCDA), network analysis, and scientometrics. Finally, this research reviews diverse practices and identified the core difficulties faced by developing countries struggling to achieve sustainable urbanization.
