Abstract
Urban transport systems in the twenty-first century are no longer confined to the basic function of providing physical mobility. They have gradually evolved into dynamic infrastructures that influence economic development, digital transformation, and sustainable practices. This study examines the role of Chennai Metro Rail Limited (CMRL) as a transformative urban mobility initiative that integrates advanced technologies with commerce, contributing to what may be termed as Commerce 2.0. The research relies on a descriptive and analytical methodology, using commuter surveys, official metro data, and secondary literature to evaluate how digital ticketing systems, mobile payment platforms, QR-code ticketing, and station-based commercial hubs are reshaping commuter behavior and urban business opportunities. It highlights how CMRL has succeeded in reducing travel times, improving commuter satisfaction, and attracting retail investments in station premises. The study also emphasizes the sustainability dimension, showing that the metro has substantially reduced dependency on private vehicles, thus lowering urban pollution. With the ongoing Phase II expansion, Chennai Metro is expected to bridge crucial connectivity gaps, strengthen last-mile integration, and develop into a digital-commercial ecosystem by interlinking with e-commerce and mobility service providers. This dual role of CMRL—as a transport facilitator and as a commerce enabler—underscores its potential as a model for other Indian and international urban contexts. The paper concludes with policy recommendations on inclusivity, affordability, and technological innovations that could further amplify the metro’s role in shaping urban commerce and sustainable development.
