Many of the existing flyovers (Example: Silk-board junction on hosur road) in bangalore can be easily made signalless intersection with little modification similar to "Cloverleaf interchange".  Hebbal interchange is another disaster. With so many flyovers one would expet signalless interchange, but still there are signals. After investing so much on these huge flyovers and we still have signals means we need to rethink about our designs! Is it not?

OK what is "cloverleaf interchange?


From: www.kurumi.com/roads/interchanges/cloverleaf.html
History

The first cloverleaf opened in New Jersey (at routes 4 and 25, which are now US 1/9 and NJ 35) in 1929; it is scheduled to be replaced with a diamond interchange around 2004. The interchange was under consideration for the National Register of Historic Places, but was declined, primarily because of the many safety and capacity-related alterations to it over the years: "widening and curb replacements for both roadways, revised geometry for one ramp, placement of a center barrier on Rt.US 1&9, removal of bridge pilasters, and the addition of modern lights and guide rails." Thanks to Raymond C. Martin for this information.

The Full Cloverleaf

  The classic cloverleaf allows "non-stop" full access between two busy roads. Traffic merges and weaves, but does not cross at-grade; unless the interchange is too congested, no stopping is required. The colloquial "cloverleaf" is the same as the more technical "full cloverleaf", as you can omit ramps to get a partial one.
    Typically a cloverleaf is used where a freeway intersects a busy surface street, though many older freeway-freeway interchanges are also cloverleafs. As we'll see, the full cloverleaf is not considered as applicable in some situations now as it might have been a few decades ago; in several places cloverleafs have been replaced with either signalized interchanges or higher-capacity directional interchanges with flyovers.

The cloverleaf is the simplest way to connect two freeways. The only bridges required are to separate the two roadways. If land is expensive, so too can be the cloverleaf, which becomes a choice between tight turning radii (and lower design speed) or lots of consumed land. You'll notice that most loop ramps are banked to counteract centrifugal forces.
    A small advantage that "falls out of the design" is the "second chance:" if you miss the first ramp to the right, you can simply take three loops in a row to get back on track. (I've also used two loops of a cloverleaf to make a U-turn.)

1) Returning to India? Good... Welcome to India...
2) Returning to Bangalore? Fantastic... Welcome to Garden City...
3) Got an offer from a company located on "Hosur road" or "Electronic City"? Oh! No...

Wait... Think again...
Ask any of your friends about commuting on Hosur Road.
Ask any of your friends about traffic cohos on Hosur Road.
Ask any of your friends about time wasted on Hosur Road.

Let me tell little bit of my experience on this road!

I spend at least 90 minutes/day on hosur road alone for travelling just ~24KM

Why? Traffic Jam, Bumper to bumper traffic etc...

Some main reasons are...
1) No pedestrian under/over bridges [as a result all the pedestrians are on the road disturbing the traffic].
2) Lots and lots of side roads.
3) Bus stops on the road itself.
4) Break down vehicles just standing on the road, not caring for anybody!
5) No lane discipline!
6) Recently they have put heaps of mud which is occupying 10% of the road along the road. And since three days nothing has been done.
7) and many more

Thousands of IT companies/Garment factories/BTcompanies etc., are located on Hosur road (from Koramangala to Electronic city). [I dont understand why everybody is so mad about opening a company on Hosur road!] Commuting between Silk board junction till Electronic City (around 14KM stretch) is really really tough. If you are new to Bangalore, you may ask, Why? and why dont you take alternative road. As usual with Bangalore! Hosur road is the ONLY road leading to Electronic city. Absolutely there are no alternatives. [Readers, please correct me if I am wrong] This roads has to accommodate hundreds of thousands of vehicles every day.

Couple of months back (immediately after some roar of IT gaints against government) there was a news about elevated highway! It seems to have stopped immediately after the soil test.

Elevated highway sounds good, but it may takes long time to implement. In Bangalore if a simple bridge take nearly 2 years imagine how long it may take to build a elevated highway of ~12KM.

Bangalore simple solutions? Like another immediate alternative road, Pedestrain passes to existing road. Widening the existing road. Real traffic police on this road rather than contract workers!

So until this road problem is solved I suggest you to wait and hold on about your relocating plan. I am afraid that your wait may continue for ever.

If you want to be kind on yourself think about alternatives. Save ~10hr/week for yourself by avoiding "Hosur road" the Nightmare.
