As a result, vehicles burn more fuel and thus emit more smoke. According to the police, the matter has been discussed at various levels including Delhi government but no plan has been chalked out to decongest these areas.

According to the traffic police, they have prepared the list of places and junctions which are polluted due to jams as vehicles are burning more fuel. Traffic Police Special Commissioner Muktesh Chander said that the matter has been discussed at an appropriate level, and the government has assured in helping to sort out the issue. "There are bottlenecks and junctions where vehicles burn more fuel and pollute the air. Various roads have different issues including structural issues. To make these areas less, polluted smooth flow of traffic is very important. We have prepared a list of 15 major and 50 minor places where vehicles burn more fuel," Muktesh Chander said.

Station Road junction in front of Dhaula Kuan Metro Station is one of such roads which has been identified by Delhi Traffic Police. According to the police, here vehicle has to wait for long and have to burn more fuel. "At this particular junction a car has to burn at least 24 per cent more fuel due to a bottleneck in front of Subroto Park. This stretch is one of the most polluted areas in Delhi as well," a senior traffic Police official said.

We have discussed this issue in various meetings that we can if we cut down the idle time of a vehicle at these junctions, pollution at these areas will come down immediately. We are working to find out a solution to decongest these areas," Chander said.

According to a traffic police, heavy vehicles are the biggest problem and create pollution. Areas like NH-8, Anand Vihar, NH-24 By Mail Today Bureau in New Delhi City's black zones scar AAP govt's anti-pollution plan Delhi Chief Minister Arvind Kejriwal, and Deputy Chief Minister Manish Sisodia discuss the odd-even scheme with Home Minister Rajnath Singh in New Delhi on Wednesday.

Areas like NH-8, Anand Vihar, NH-24, etc. are more polluted than any other area during night hours as trucks, buses move in large number after 11 pm till 7 am.

According to a survey conducted by Central Road Research Institute, Delhi is wasting, at least, Rs 87 crore worth of fuel at traffic jams only in a year. The amount of fuel burnt in just idling of vehicles at traffic intersection amounts to 39,806 Kg (diesel, petrol and CNG vehicles combined) and the quantity of Carbon Dioxide produced equals 1,15,609 Kg, that is 115 tonnes of climate warming and extremely unhealthy black soot.

Maximum idling delay in morning peak hours was recorded at Shastri Park (over 700 seconds), followed by Nirman Vihar (over 550 seconds) and Kingsway Camp (over 350 seconds).

The maximum idling delay at evening time was recorded at Kingsway Camp (over 700 seconds), Patel Nagar (close to 700 seconds) and Ashram Chowk (650 seconds). From 5 am to 8 pm in the day, 7.20 pm was found to be the most traffic-jam prone time clocking an average of 350 seconds of idling delay all across the city.

The study was carried out at eight traffic junctions located in different parts of Delhi. Ashram Chowk in southeast Delhi was found to be most polluting, wasting 11,038 kg of fuel and producing no less than 31,974 kg of Co2. Peeragarhi in the West came next burning 8,260 kg of fuel and emitting 24,119 kg of Co2, followed by Badli Crossing in the northwest, guzzling 5,617 kg of fuel and producing 16,535 kgs of Carbon Dioxide. Preet Vihar, Shakti Nagar, Paharganj, KG Marg and Lodhi Road queued up in exactly the same order in the list.
