摘要

In rapidly urbanizing Bengaluru, expansion of the metro rail network over the last two decades has significantly influenced urban land use patterns. This study evaluates spatio-temporal Land Use and Land Cover (LULC) transformations induced by the metro from 1997 to 2024, focusing on changes in urban form and development intensity. Multi-temporal satellite imagery and geographic information system analyses within 0–500 m, 500–1000 m and 1000 –500 m buffer zones along corridors assessed Transit-Oriented Development (TOD) impacts and quantified metro induced changes, employing robust methods. Four LULC classes were classified, including built-up area, vegetation, open land, and water bodies, and land use transition dynamics were examined using Sankey flow visualization. Results show built-up area in the influence zone more than doubled, rising from 19.59% in 1997 to 51.90% in 2024, primarily at the expense of open land. The most pronounced expansion occurred in the 500–1000 m zone, suggesting intensified development beyond station areas. Increasing green cover in later stages of metro expansion reflects landscaping and green infrastructure initiatives. Findings highlight the metro’s role in promoting compact urban growth and demonstrate the value of geospatial techniques for sustainable TOD in spatial information science and urban planning.
