On the basis of a week long traffic sample survey at Gurgaon toll expressway, KPMG has projected that due to under-reporting of atleast 79,000 passenger car units (PCUs) daily by the operator, National Highways Authority of India lost about Rs.24 crore in 10-months. The company kept showing only 1.81-lakh PCUs as average daily traffic but actual figure was around 2.55-lakh.
