The minister said the PRTC was also planning to increase the number of both air-conditioned and non-air-conditioned buses to ease the congestion on roads of various cities, and officials had met central Road Transport Minister Kamal Nath and sought his help for the purpose.

In the 1960s, public transport buses constituted 12 percent of total vehicles on Punjab roads but in 2005-06, this figure declined to only one percent, he said.
