Last week, Chief Minister Arvind Kejriwal had alleged that BJP and RSS wanted to "sabotage" the scheme, when auto unions had called a day-long strike which was later withdrawn.
"Since the (second phase of) the odd-even scheme has started, we have noticed that traffic congestion has suddenly increased on the roads. Some auto unions had called a strike and now, municipal landfill sites and a forested area near Raj Ghat have caught fire.
He said traffic jams were not a result of the car- rationing formula and claimed that most of the vehicles being spotted on the roads were from Uttar Pradesh and Haryana, which is "unusual".
He said that from January 1 to April 14, 1,63,907 vehicles were registered with the city's transport department and out of them, 1,44,005 were private and the rest commercial.
2,14,394 vehicles were registered from September to December last year and of them, 22,934 were commercial ones.
Between January 1 and April 14, 12,126 private vehicles were fitted with CNG kits as against 5,463 from September to December last year, he said.
The data indicates that the scheme is not the reason behing the traffic jams in the city, "but there is some other reason contributing to chaos on roads", he said.
The Minister claimed that the government has received an audio clip of telephone conversation between a DTC bus driver and an unknown person, in which the former was demanding Rs 1,000 for halting the vehicle on the road as a break-down bus.
