After spending several gruelling hours under a hot on Thursday sun monitoring the traffic flow on the Ambedkar Nagar-Moolchand Bus rapid transit system (BRTS) corridor, officials worked hard to sort out glitches, especially after chief minister Sheila Dikshit's veiled threat to scrap the new bus corridor. Delhi's transport minister Haroon Yusuf, who made a personal visit to the stretch, said that efforts were being made to rectify the loopholes and that the things would further improve in days to come. "There is substantial improvement in the traffic flow. Every possible effort is being made to fine-tune the corridor's functioning," Mr Yusuf said. Clearly, the Delhi government on Thursday doubled up effort to salvage the controversial project. But opposition to the corridor is building up and the issue found resonance in Parliament as well a day earlier. The main Opposition Bharatiya Janata Party (BJP) launched a scathing assault against Dikshit's government for launching an ill-conceived and hasty scheme. The party's senior leader and member of parliament from south Delhi V.K. Malhotra on Wednesday raised the issue in the Lok Sabha and sought the corridor scheme be scrapped. Ms Dikshit is under tremendous pressure from her own party leaders to find a way out and not risk public outburst in view of the assembly elections in November this year. Several members, including Mohammand Salim of the Communist Party of India-Marxist, supported Mr Malhotra's plea. Earlier, calls to scrap the BRTS corridor were also made in the Rajya Sabha. Chief secretary Rakesh Mehta inspected the corridor on Thursday. Senior officials from the implementing agencies accompa nied him.
