Assessing the Impact of Metro on Spatial Characteristics - Case of Rajajinagar, Bengaluru

The introduction of a mass transit system in a city is expected to influence the spatial characteristics of the neighborhoods surrounding transit stations as it catalyzes economic growth and urban regeneration.  A thorough exploration of the impact on land use, built form, and land value may facilitate the successful implementation of transit-supportive development in the influence zone of mass transit. Hence, it is critical to understand the impact of a mass transit system on the built fabric of a predominantly brown-field development. This analysis further helps explore strategies for optimizing limited urban space and creating more livable neighborhoods. This research paper is an effort on the part of the Directorate of Urban Land Transport, Government of Karnataka to document the methodology and approach used for assessing the spatial impact of a mass rapid transit system on a neighborhood in its influence area so as to derive insights for developing appropriate regulations to encourage transit-oriented development. This study focuses on assessing the impact of the metro on the spatial character of the core Transit-Oriented Development (TOD) zone, which refers to the 500-meter walking catchment area around the Rajajinagar neighborhood in the city of Bengaluru. It aims to evaluate and quantify the spatial transformations occurring in the immediate vicinity of the metro station, within its walkshed, and explore the factors influencing these changes.

The study captures plot-level data on land use, building heights, plot areas, and floor-wise uses through detailed on-site and household surveys. The dataset collected was analyzed and compared to the developments recorded in 2014 when the metro system was first operationalized. The recorded spatial transformations were further validated through statistical analysis. The study helped in understanding the impact of mass transit stations on spatial transformation and its dynamics. Furthermore, it provides a detailed methodology for conducting spatial assessments facilitating the development of TOD zone plans. Building on the learnings from this research, the methodology and approach have been fine-tuned for application in similarly placed transit zones.
