The railways are the lifeline of Mumbai and the buses of the Brihanmumbai Electric Supply and Transport (BEST) are the feeder system (part of the bigger transport network). Seventy-three per cent of BEST passengers travel up to 6 km every day. This means 21.60 lakh of the average 29.60 lakh daily passengers travel up to 6 km in the 4,043 BEST buses, as per figures in January 2016. Now BEST has introduced new stages in their ticketing format, which will reduce the ticket fares. But, this will not benefit the 73% passengers who form its base.
