In a major leap forward to enhance connectivity and streamline urban mobility, Chief Minister M.K. Stalin on Monday launched the mobile application Chennai One, which provides an integrated QR code–based ticketing system for all modes of transport—buses, Metro Rail, suburban trains, and autos.
Hailed as the first city in the country to achieve this milestone, Chennai now offers a seamless commuting experience through the app, which also doubles as a journey planner. The Chennai Unified Metropolitan Transport Authority (CUMTA), which developed the app, described the all-in-one digital platform as a “game changer” that brings multiple modes of public transport under a single umbrella.
“This will make commuting easier. Positive feedback has already been received from the public, which will be taken into account to make Chennai shine as the best in the world in #PublicTransportSystem,” Stalin posted on X.
The app, available for both iOS and Android platforms, was launched following successful trials that began in June. A key hurdle that delayed the rollout was resolving the issue of platform fees. It was settled with the State government agreeing to bear 1.39 percent of the ticket fare charged through the app. The government is expected to pay approximately ₹3 crore annually toward this.
Further, CUMTA officials confirmed that the State government has already deposited ₹30 lakh into the account of Southern Railways as rolling funds. Southern Railways can deduct ticket fares from this pool, which will be reimbursed from daily fare collections.
This landmark initiative, a digital gateway for urban commuting, is part of Chennai’s 25-year comprehensive mobility plan. By eliminating the need for multiple ticketing systems, it offers a model that urban planners believe can be replicated in other cities across India.
