DMP's new toys and eyewash

We have read about the DMP's old toys, the CCTV cameras etc (Tk 61 crores) and now their latest, the multi crore “automatic traffic control lights” on road intersections together with “lanes” demarcated on the VIP roads for slow and fast motorized vehicles. All very progressive indeed!!!. My experience last Sunday to receive my son-in-law from the 11:am Emirates flight was a nightmare, however.
We left at 10:am and travelled, Niketon-Gulshan Ave-Kemal Ataturk-Airport Road and reached there around 10.50 without too much fuss. We left the airport at 12.45pm and from the start it was at snail's pace with bumper to bumper traffic on Airport Road- Mohakhali- Gulshan South Avenue-Niketon, arriving at home at 02.50pm (2 hrs 5 minutes for a 30 minute journey). Whether the new traffic lights were working or not, I do not know, but I saw plenty of cops waving their arms and batons. With lots of time to observe the movement of traffic at very close quarters, I would sub-divide them as follows in terms of numbers 60% private cars (very few carrying more than one passenger), 30% buses (chockfull of peasants) and 10% CNGs and others. In terms of occupying road space, it would be 80% private cars, 15% buses and 5% CNGs and others. I did not see much improvement in cars keeping to their lanes, they were weaving about much as usual as there was no supervision!.
Who will answer these questions: 1) Who will benefit from these traffic improvements? 2) How many roads in Dhaka are broad enough to have multi-lanes? 3) What happens when the lights go-blink as they surely will do regularly? 4) How many traffic cases have been instituted since these rules were enforced and how many were for private cars and how many for buses and CNGs? 5) How many private cars have been fined or towed away for illegal parking on public roads? 6) What have the authorities in store for rickshaws who carry 50%+ of Dhaka's population every day and rickshaw vans who transport more goods than all the trucks that bring in produce from outside Dhaka?
