Traffic roundabouts
S A Mansoor, Dhaka
While going through Sultana Rahman's city column in your paper of 27th October on "Fountain on a faulty roundabout" made me remember parts of a write up in a US "Traffic Engineering" publication many years back.In that article it was mentioned that roundabouts are suitable for managing traffic in intermittent low density traffic pattern where proper driver discipline can enable traffic to cross at right angles or take ninety degree turns without traffic lights or traffic policing. However it was stated that there must be clear all round visibility across the roundabout without any visual hindrance. In contrast in Dhaka the roundabouts are profusely blocked with fountains, hoarding and dense bushes. There is no visibility across the roundabout. Regarding traffic stream, it is bumper to bumper usually and continuous. Of driver discipline the least said the better. Four policemen are needed for all the four roads that come in and out of the roundabout, and the policemen too cannot see across the roundabout. Too sum up; a real mess of a situation is created by our road builders, architects and advertising income hungry city corporation. Nobody cares or bothers about the needs of traffic management or road safety. The excuse is that there should be traffic lights to control the traffic. When we will have failure proof traffic lights is another mystery! The minimum requirement for a satisfactory traffic control needs traffic lights with automatic change over timers, high quality bulbs, voltage regulators and large capacity UPS to cater for the power shut outs that could extend any where from minutes to hours! All this needs a lot of money. I wonder if we have taken proper steps in this direction? Any stopgap or technically incomplete setup will cause the same problems again. However if there is a will there is a way. Do we have the will; or we prefer to live in confusion?
