Spatial Accessibility Indices at Rural Wards of Dodoma Urban District, Tanzania

This study aimed at illustrating the limitations of the binary/zonal travel impedance weights and the potential of fuzzy set theory in defining continuous travel impedance weights in Floating Catchment Area (FCA) measures. To illustrate this in a real-world, the study implemented the Enhanced (E) Fuzzy-based (F) Two-step Floating Catchment Area (2SFCA) measures to calculate spatial accessibility of water points in Rural Wards of Dodoma Urban District, Tanzania. The resulting E2SFCA and F2SFCA accessibility indices are provided in this repository.本研究旨在阐明二元/分区出行阻抗权重的局限性，以及模糊集理论在浮动供需法（Floating Catchment Area，FCA）测度中定义连续型出行阻抗权重的应用潜力。为在现实场景中验证该结论，本研究采用增强型模糊两步浮动供需法（Enhanced (E) Fuzzy-based (F) Two-step Floating Catchment Area，2SFCA），对坦桑尼亚多多马市区乡村片区的取水点空间可达性进行测算。本仓库现已提供经计算得到的E2SFCA与F2SFCA可达性指数数据集。
