Tamil Nadu Chief Minister M.K. Stalin is set to unveil a landmark 25-year Comprehensive Mobility Plan (CMP) for the Chennai Metropolitan Area next week, alongside the launch of a unified QR-code-based ticketing system that will integrate all major public transport modes in the city.

The announcements will be made during the second governing board meeting of the Chennai Unified Metropolitan Transport Authority (CUMTA) at the State Secretariat, according to an official release.

Covering 5,904 sq km, the CMP outlines a roadmap up to 2048, aiming to create an "integrated, seamless, safe and sustainable transport ecosystem" in Chennai. The plan focuses on increasing the share of public transport, ensuring affordable fares, integrating bus, metro, and para-transit services, and promoting eco-friendly mobility through non-motorised transport options.

In addition, CM Stalin will introduce the Chennai One Mobility App, available on iOS and Android. The app allows commuters to plan journeys, track services in real-time, and purchase digital tickets via UPI or card payments.

Its signature feature, ‘One City, One Ticket’, enables passengers to switch seamlessly between buses, metro trains, and suburban rail using a single QR code – the first such facility in any Indian city. The app, available in Tamil, English, Telugu, and Hindi, is expected to reduce ticket counter queues and simplify transfers.

"With just a few taps, passengers can plan, pay and travel across modes – a landmark reform for Chennai’s public transport," said CUMTA special officer I. Jayakumar.

Transport planners believe that the CMP, combined with the unified ticketing system, could serve as a model for other metros aiming to integrate services and enhance commuter experience.

Through these initiatives, Chennai aims to improve mobility, reduce congestion, and cut pollution, positioning itself at the forefront of sustainable urban transport reforms in India.
