so many wonderful old trees were cut around KR cricle..the canopy there was the best and even harsh summers were shielded compeltely for road users..

now its barren nothing..which has also turned into something useless!

I second the thought that BBMP has to keep away from doing anymore innovative cheap implementations and leave the roads to the experts..allmost all their works are uselessly designed!

I'm not surprised. The new airport road might be providing a fast ride to & from the airport, no doubt, but did they ever consider how it had impacted others that were passing on part of the road - say someone from Kumara park or Malleswaram to Shivajinagar ?

The answer is to reduce the no. of vehicles on the streets & not keep widening or building roads & installing magic boxes all the time - they will not last long without other interventions !

Do they even realize that they are leaving permanent scars on Bangalore in their haste to make the ride quick (at least for a year or so) for car users?  Let's assume this does not resolve the traffic situation?  Then how does one undo the damage?

Read in DH the rotary has been referred to an expert committee to reveiw feasibility.  This after the underpasses, the rotary itself have been completed.  If this is how our agencies work, it is no wonder our city is the mess it is.

"Following a meeting between the Palike and the Traffic Police, it is learnt that the K R Circle Rotary has been referred to an expert committee for a feasibility study.
The controversial Rotary was created under the aegis of the then Palike Commissioner, Subramanya for easing the flow of traffic along K R Circle. It was alleged back then that the Traffic police was not consulted for building the Circle.  "

It really annoys me that BBMP continually makes one disaster after another and gets away with it. I cannot think of a single large infrastrutural project executed by BBMP which has been successful. Kaveri junction, BDA junction, the whole Bellary road - RT Nagar stretch - KR circle etc are all disasters. The ONLY thing which has really worked is the improvement of kerbs, footpaths  and roads which has been happening over the last few months. And this is the cheapest and least damaging. I dont know when they will wake up to this realization. In most instances a combination of lights, one ways and well designed intersections would have the same effect as these magic boxes, road widending. etc.

Found this nice video on using round abouts..KR circles desperately needs markings and road signs..

 

I think its not a bad design afterall..its just how we use it!

Good video, first they should make such clean junctions, second they should play these videos on TV since the RTO and driving schools dont know these things enough to test for them.

As you may have noticed most roundabouts are not designed for high speeds since banking the roads are not appropriate. The widening of roads and signal free junctions have made travel speeds higher which means the vehicles need to be told to slow down to atleast 5kmph above the roundabout limit before approaching it. Since you cant go from 60 to 20 in 100 meters the slow down has to start way early and in steps of 5 /10kmph so as not to brake too hard. Of course there will be complete stops at the entry of the roundabout when giving way to traffic already in the circle.

Thus, firstly, a roundabout, while is signal free, is not the same as stop free. Second, if we dont manage the flow smoothly, with appropriate education of how to drive in the roundabout followed by proper signage like lanes and speedlimit posts, there is bound to be chaos and backups due to jamming.
