Being the most important entry-exit point of the city, the terminus has a capacity to handle over 2,000 buses and 200,000 passengers a day. The terminus currently handles more than 500 buses at a time, and 3,000 buses and 250,000 passengers a day.

There are provisions for parking 1,500 to 2,000 two-wheelers and 60 cars on the premises of the bus terminus. A two-level underground two-wheeler parking lot was mooted in 2008 to decongest the entrance for the buses, which jostle for space with two-wheelers and cars. Initially, the project cost was estimated at ₹ 90 million. The underground parking project was taken up based on a study that estimated that the number of motorcycles parked there would be increased to 3,000 a day in the future. Work on the 6,000-sq.m project began in January 2009 and was completed in August 2010 at a cost of ₹ 170 million.
