The Odd-Even scheme has worked to an extent in other countries but may require more supporting transport infrastructure here to make travel comfortable for commuters, leading industrialist Ratan Tata said today.

Tata declined to get into the merits of the scheme that is being followed in the capital till January 15, saying that he is not the 'qualified person' to comment on it. "Even Odd licence plate solution has been tried in other countries. It has worked to some extent. So I am not quick to dismiss it...may be it needs more supporting (transport) infrastructure to make it comfortable to other people to avail it," Tata told reporters in New Delhi.

The Delhi government introduced the Odd-Even formula for fortnight from January 1 to check pollution in the city. Under this scheme private 4-wheeled vehicles bearing registration numbers ending with even number can ply on roads only on even dates like 2,4,6,8,10 from 8 am to 8 pm.
