New Delhi, Jan. 7 -- State-owned National Highways Authority of India (NHAI) on Tuesday said it has sought urgent intervention from the Department of Telecommunications (DoT) and the Telecom Regulatory Authority of India (TRAI) to improve mobile network connectivity on National Highways. NHAI in a statement said as part of a comprehensive assessment undertaken by the state-owned agency, 424 locations covering about 1,750 km across the National Highway network have been identified as critically affected due to non-availability of the mobile network connectivity. "Identifying critical mobile network connectivity issues across several stretches of National Highways, NHAI has sought the intervention of DoT and TRAI to issue appropriate directions to Telecom Service Providers (TSPs) for addressing non-availability of the mobile network connectivity on several stretches of National Highways, particularly on greenfield and remote sections," it said. Emphasising public safety implications and the strategic significance of the National Highway network, NHAI said it has called for an expeditious and coordinated approach to improve mobile network connectivity on the national highway corridors across the country. "Detailed information on these locations has been compiled and formally shared with the Department of Telecommunications and Trai for necessary action," it said. NHAI said as the National Highway corridors traverse through remote and rural areas, absence of dependable mobile network coverage on these sections adversely impacts National Highway operations, emergency response mechanism and delivery of technology-enabled public services. In addition, NHAI said it has requested TRAI to issue necessary directions to telecom operators for dissemination of proactive SMS or flash SMS alerts at geo-mapped accident-prone locations, including stretches affected by stray cattle movement and other hazards....
