Delhi Chief Minister Arvind Kejriwal today indicated that the 'odd-even' restrictions for plying of private vehicles will be tried for a limited period and will be "halted" in case it creates trouble for people. With experts and Opposition parties questioning the practicality of the scheme, Mr Kejriwal said many things are to be thrashed out before its implementation including talks with the Centre and police as they will have to be taken on board.<br/><br/>Kejriwal said at HT Leadership Summit that his government had planned to introduce the scheme at a later stage after building a dedicated and elevated bus corridor. He said however, he was forced to take the drastic step following a situation of emergency and panic in the wake of Delhi High Court's observation that the city has become a gas chamber
