Planning improvements are integral to the urban development initiatives envisaged for new and existing areas. These improvements include strategic distribution and provision for civic amenities such as parks, commercial centres and transport lines, around planned residential areas. Recent studies have identified that planning improvements uplift land value in its neighbourhood; however, the degree of upliftment varies with the quantum and mix of improvements prescribed. Studies have also quantified the impact of various factors such as, transportation lines, urban greens, and parcel sizes on the value of land, however, the cumulative impact of all improvements has not been discussed adequately. Therefore, the objective of this study is to develop a methodology to quantify the impact of planning improvements on residential land values. Since the impact of planning improvements on value of land is governed by its proximity to the interventions, therefore, a GIS-based regression modelling approach is adopted for the study. Data for the study was collected in multiple layers, the market price of the vacant residential land was collected through one of the leading properties listing portals and the proximity parameters of urban amenities are identified from “PARIMAN” the Geo-Portal of the NCR Planning Board. The study focuses on residential areas of Noida—a satellite town of Delhi and it generates a proximity dependent model which can be used to quantify the impact of planning improvements on residential land values. The results also highlight that urban amenities in the immediate neighbourhood contribute more towards value of land as compared with distance from city centre. The findings of this study have the potential to evaluate and suggest possible planning scenarios being considered by authorities for urban development.
