The mobile app that underwent trials for many months aims bring in a seamless commuting experience for travellers in city.This app works as a journey planner for a commuter and offers multiple options of commuting including buses, Chennai Metro Rail services, suburban trains or autos.The plan for developing an app to create a single QR code was mooted by Chennai Unified Metropolitan Transport Authority (CUMTA) more than two years ago and following that, CUMTA did the ‘Journey Planner-cum-Integrated Ticketing in Chennai Metropolitan Area’ study.With 47 lakh travellers in the city commuting using different modes, CUMTA felt such an app could significantly benefit commuters if an app can help them plan their daily travel and generate a single QR code ticket that can be used in all these modes. Subsequently, they floated bids, awarded the contract for this building the app. Early this year, CUMTA started trials for the app before the launch on Monday.
