The Yamuna Expressway industrial development authority (YEIDA) on Wednesday said that it has roped in the Indian Institute of Technology (IIT), Delhi to conduct a safety audit of the 165-km Yamuna Expressway connecting Greater Noida with Agra. The Institute has been instructed to finish the audit by the next four months and suggest ways to reduce accidents on this high speed expressway. “IIT-Delhi will start audit work in August and finish it in four months as we need to implement the suggestions in the report at the earliest. The motive of this audit is to ensure safety to motorists who use this E-way,” Arun Vir Singh, chief executive officer of the YEIDA, said.Following criticism from the Supreme Court hearing a petition seeking motorists’ safety on the expressway, the Uttar Pradesh government had, many times, directed officials to beef up law enforcement to contain speeding and other traffic violations causing accidents killing hundreds of people. But the apex court is not satisfied with the safety measures taken so far, said officials. According to data provided by YEIDA, there have been 4,984 accidents on the expressway between October, 2012, and April 10, 2018, resulting in the death of at least 540 persons.YEIDA had, on December 25, 2014, hired the Central Road Research Institute (CRRI) to conduct a safety audit of the expressway after frequent accidents resulting in casualties were reported. But the CRRI recommendations hardly made any difference to enforcement, said officials. “We explored other options and tried to hire IIT Roorkee and IIT Delhi, as well as other agencies. IIT Delhi agreed to conduct the audit which will cost the authority ₹34 crore. We will implement all the suggestions of IIT Delhi for motorists’ safety,” another YEIDA official said.According to the CRRI, the main causes of accidents on the expressway are speeding, not driving in the correct lane, drink driving and overloading of heavy vehicles. The expressway passes through six districts — Gautam Budh Nagar, Bulandshahr, Aligarh, Hathras, Mathura and Agra. The police in the six districts keeps passing the buck to one another instead of enforcing traffic rules.The speed limit for small vehicles is 100 km/hr whereas for heavy vehicles it is 60 km/hr.
