The projection of "normalcy on ground" will be the focus of Lockdown 4.0, which comes into effect from May 18. A senior home ministry official told NDTV that one of the first areas where relaxation will be allowed wherever possible, is public transport -- on ground and the skies. The boundaries will be based on the states' blueprint -- sought by Prime Minister Narendra Modi earlier this week -- and how compatible it is with the situation on the ground, officials involved in drawing up the Lockdown 4.0 guidelines told NDTV.
