At present, there are around 80,000 autorickshaws plying across the national capital.
"Transport Department (of Delhi government) is yet to take a decision on around 18,000 applications, which is pending for seven months, to issue new permits for allowing more new autos on the city's roads.
"After government's even-odd formula, there will be huge crowd of passengers on roads. As DTC and cluster buses don't have sufficient numbers, government should allow pending applications for new permits," Rajendra Soni, Delhi Autorickshaw Sangh's general secretary, said.
Soni said auto unions will support government's even-odd formula if it agrees to issue more permits so that new autorickshaws could come on roads to meet the rush.
Outlining the contours of its ambitious plan to curb pollution through odd-even number plate formula, Delhi government, earlier in the day, said that odd-numbered cars will be allowed to ply on Mondays, Wednesdays and Fridays while even-numbered vehicles will run on Tuesdays, Thursdays and Saturdays.
