NEW DELHI: The number of vehicles on roads came down significantly on Monday, the first day of Delhi government's odd-even road rationing scheme, with Chief Minister Arvind Kejriwal saying he was getting reports that people were following it nearly 100 per cent.The anti-pollution measure kicked in from 8 am in Delhi and Chief Minister Arvind Kejriwal urged people to follow the scheme for the sake of their family and children.Kejriwal carpooled with Delhi Health Minister Satyendra Kumar Jain and Labour Minister Gopal Rai to reach the Delhi Secretariat.While Deputy Chief Minister Manish Sisodia rode a bicycle to from his residence, Transport Minister Kailash Gahlot travelled in his OSD's car to reach the secretariat."I am getting reports that people are following it nearly 100 per cent and only a few challans have been issued. I thank Delhiites for their cooperation. Recently, we defeated dengue and it is now time to control pollution in the national capital," Kejriwal said.Responding to questions over deployment of less traffic police personnel on roads, he said they should back the initiative and if the need arose, he would talk to the lieutenant governor about it.Gahlot said that he was on Delhi roads for two hours and he was happy that basic compliance was being done. "Most of the vehicles are even numbers. I thank all Delhiites for their cooperation," he said.Under the scheme, apart from exempted categories, only those non-transport four-wheeled vehicles will ply on the roads which have registration numbers ending with an even digit.The overall Air Quality Index (AQI) of the city at 7:30 am stood at 439, which falls in the 'severe' category. An AQI between 0-50 is considered 'good', 51-100 'satisfactory', 101-200 'moderate', 201-300 'poor', 301-400 'very poor' and 401-500 'severe'. An AQI above 500 falls in the 'severe plus' category."Namaste Delhi, odd-even is starting from today to reduce pollution. Please do follow it for yourself, your family, kids and your breath. Share cars. It will strengthen friendship, form relations, save petrol and pollution," Kejriwal said in an early morning tweet in Hindi.He also appealed to auto and taxi drivers not to overcharge commuters and urged them to take part in the scheme.Violations of the odd-even rule will invite a fine of Rs 4,000.
