National Highways Authority Of India [NHAI] — need variable/dynamic led boards on smog affected highway in north india to avoid collisions

Watched one of the trending video today where vehicles ramming into one another on a smog affected affected yamuna express highway in north india. I guess, action is somewhat feasible with the ready technologies we have in our hands.. Use of hazard lights, fog lamps and being in cotrollable speed (Normally convert every 2 metres of visilbility to every km/h of speed - so a visibility range of 50m means a max speed of 25 km/h) are the self defense techniques to help youself and everyone on the road. Additionally, this is what we need! This variable/dynamic led boards are life saviors and could really control vehicle pile-ups on highways near delhi and other states during smog affected winters. These led boards which can be seen from few hundred meters away at least, should be kept at regular intervals extensively during winter and rainy mornings and nights.
