Also I have a say on "Odd - Even" formula that it can be a temporary solution to the problem but not a permanent one; Because if today Odd Even is accepted solution then in future another mathematical combination can be a solution like vehicle number ending with 1 to run on 1st, 2 to run on 2nd and 9 on 9th and 0 on 10th of month and 1 again on 11th and so on..! At the end such solutions will add more vehicles to the street as those who can own more vehicles will buy it. This will also promote corruption as people will buy the numbers from RTO to ensure that their new purchase is worth.
Possible steps to be taken to reduce pollution
Any suggestions from your side? please post in comments. thanks
