To cut down vehicular pollution and minimise road congestion; It is time for policymakers to come out of traditional policies, and use smart technologies to put an end to the traffic mess.
To reduce traffic congestion and improve safety, many cities start considering the use of “roundabouts.” Roundabouts are used throughout the world, to reduce accidents, traffic delays, fuel consumption, air pollution and construction costs, while increasing capacity and enhancing intersection beauty and used to control traffic speeds in residential neighbourhoods, also accepted as safe type of intersection design.
For those not familiar with the terminology, a roundabout is an intersection with a circular traffic flow pattern, where drivers enter the intersection and travel around a center island without the use of traffic signals or stop signs.
Modern roundabout is a type of intersection control with particular design and physical geometry to control driver activities such that maximum entry flow rate relies on circulating flow. Some of these features such as yield control at entrance and splitter island guarantee vehicles traverse roundabout safely and comparatively with slower speed.
Roundabouts have safety aspect, and that is their most important feature, by far. They are good for people because they are generally safer than traditional intersections.
All the major circles in Belagavi have a Centre island, but with no signals and roundabout it is chaotic. Not all circles can have roundabouts but one like Basveshwar circle can definitely have one.
Currently no one takes a circle when the traffic signals are off, they just turn right suddenly and then find one more vehicle infront of it coming from the other side.
Many dont even know that at a circle it is always best to take a roundabout which avoids head on collision. I have seen this at Sanhayni Circle, Chennamma Circle where if the drivers keep to their left and take a roundabout the island/police post its safer and even faster.
Roundabouts are not the solution to all traffic problems at all locations. Careful study is required to identify the most appropriate control method at any given location. A modern Roundabout should be considered as an alternative traffic control to traffic signals and stop sign control.
