CHENNAI: Chief Minister M K Stalin unveiled an App, ‘Chennai One,’ which is India’s first integrated public transport ticketing system, for the benefit of those using public transport, particularly those new to the metropolis or going on a route unfamiliar to them, on Monday. Launched by Chennai Unified Metropolitan Transport Authority (CUMTA), the nodal agency for transport in Chennai, the App would, to start with, integrate Metro Rail, MTC bus services, Namma Yatri auto rickshaws and taxis. MRTS services and suburban trains would soon be also integrated with the App, which would be a QR-based ticketing and journey planner, CUMTA said. By downloading the App on iOS and Android platforms, commuters can expect a seamless travel in Chennai, CUMTA said. The phenomenal growth seen by Chennai had led to commuters getting confused over the mode of transport to reach their destinations.
