Three lane traffic

Ziauddin Ahmed, Gulshan - 1, Dhaka
I have failed to understand how the three lane traffic movement will work if vehicles are categorised like private cars will ply on first lane, buses on middle lane and CNG taxis on third lane. What I have seen in developed countries is that drivers who intend to take left turn from a main road should stay on left lane, those intending to go straight should stay on middle lane and those intend to take right turn should stay on right lane. Buses that have authorised stoppages on left will definitely have to stay on left lane. No one is allowed to change lanes on busy roads and are liable to be penalised. The three lane traffic system which Dhaka Metropolitan Police has introduced is bound to cause jams at auto traffic signal crossings when on a green signal a vehicle on right lane tries to take a left turn or tries to take right turn from left lane. I am very sceptical about the three-lane traffic system that the DMP has introduced but still I hope through trial and error traffic discipline will come into force on our roads and highways.
