Delhi is the first city in the country to have a common mobility card, which can at present be used on 200 DTC and 50 cluster buses plying on different routes, apart from metro trains.
"Its a big step in the transport sector that will facilitate the seamless travel of people in Delhi," Mr Kejriwal told reporters after a short ride on a DTC bus on the occasion.
Transport minister Kailash Gahlot was also present for the launch of the pilot project.
