India is balancing rapid infrastructure growth with sustainability, particularly in its capital city, New Delhi, which spearheads the sustainable high-speed rail corridor initiative. Ghaziabad, an old satellite district to the capital, is a result of an unmanaged urban sprawl crawling out from the metropolitan core of India’s National Capital Region of Delhi. This report delves into the implications of the Rapid Rail Transit System (RRTS) for the National Capital Region of Delhi, with a focus on assessing the Public Transport Accessibility Levels (PTAL) and the integration of transit-oriented development (TOD) within local socio-economic contexts. It also discusses the pedestrian infrastructure conditions, particularly around the four station areas: Sahibabad, Ghaziabad, Guldhar and Duhai. Recommendations for the Sahibabad to Duhai stretch include point-to-point drop-offs, permeable footpaths and bike lanes interspersed with bioswales, and can be implemented for future corridor development.
