Analyzing accessibility of public open space in relation to urban configuration of Dhaka city

Abstract

Public open space plays an essential role in urban life, particularly in densely populated cities like Dhaka. Dhaka has a limited supply of land for its major urban areas; however, some open spaces are frequently criticized for being inconvenient to users and therefore underutilized. The issue of how to enhance the performance of open spaces is therefore crucial for city planners and designers. Accessibility, defined as the relative proximity of one location to another, denotes the convenience of reaching the destination from the starting point. As a spatial analytic metric, it plays a crucial role for decision-makers in determining where to locate public facilities or amenities in order to maximize their utility. In addition to the traditional accessibility measures, various factors, such as spatial configuration, opportunity attraction, and pedestrian comfort, are also considered. In this specific circumstance, the review tries to exhibit that customary openness measures to public spaces (squares, gardens, and stops) as far as time should be enhanced by other setup based measures. Space Syntax and GIS Network Analysis are two methods for determining open space accessibility. The Organization Investigation strategy estimates the distance between the open space and the neighborhoods it serves, while the space grammar procedure assesses the open space's spatial arrangement. This paper identifies the locations of these open spaces and analyses their level of accessibility using a comparative approach to both techniques. Related to public space inclusion, worldwide or nearby combination in the hub guide might bring about shifting weighting coefficients for openness examination. This study's primary outcome highlights the importance of integration as a critical factor in pedestrian movement throughout the city. Customary proportions of time related to these proportions of spatial design could be utilized to recognize roads with low degrees of openness.
