New Delhi: The odd-even traffic scheme is set to start again "for a short period", Delhi Chief Minister Arvind Kejriwal said on Thursday, adding it can't be a permanent feature. "We will start it again for a short period," Kejriwal told a group of journalists at his residence here. "This will be done in phases. We can't do it on a permanent basis," he said. Kejriwal said that the decision has been taken following the feedback on the January 1-15 odd-even scheme when only cars with odd registration numbers were allowed to ply on odd dates and those with even registration numbers on even dates. Kejriwal, however, added that two-wheelers will remain outside the ambit of the odd-even scheme because of problems related to public infrastructure. He said Delhi had 30 lakh two-wheelers and if these many two-wheeler riders were to take to buses and Delhi Metro, it would lead to chaos. "So, we can't include two-wheelers in the odd-even scheme." A formal announcement regarding the odd-even scheme will be made later this evening. Deputy Chief Minister Manish Sisodia said that the lack of traffic jams during the January 1-15 period was something that everyone in the city had appreciated.
