英文摘要
This project seeks to develop a neural network model (NNM) to produce estimates of transport andemployment accessibility in data-sparse urban areas by drawing on data from both rich and sparseurban data contexts and satellite imagery. Specifically, the project seeks to:1) Measure Transport and Employment Accessibility (TA and EA) at neighbourhood level in richandsparse-data urban settings;2) Build a NNM based on satellite imagery to predict longitudinal and geographical changes inTA and EA;3) Develop a time-adjusted weighting system for the NNM to create reliable longitudinal TA and EA predictions in sparse urban data settings.By addressing these aims, the project will innovate by developing a scalable, transferablemethodology for leveraging existing data and open access satellite imagery to create annual TA andEA estimates at high spatial resolution in sparse urban data contexts. By doing so, it ultimately seeksto help progress the United Nations' (UN) Sustainable Development Goals (SDGs) by generating nonexistent, timely, geographically disaggregated data on TA and EA in these areas (SDG 17). Specifically it seeks to inform interventions to reduce inequalities (SDG 10) and improve access to Employment and public transport (SDG 11).
