Bangalore Road Works Action BTP Transportation Infrastructure traffic advisory council TAC
Murali & Myself attended this months meeting. 2 Points emerged.
First was that the traffic police will get some monies from GoK to apply short term fixes to the city which can show visible improvements over the next 6 months. This could be tweaks to junctions to streets to anything that is not a huge civil works project involving large construcions like flyovers etc needing DPR's to execute. Citzens are expected to make specific suggestions with named places & include detailed suggestions like drawings designs etc. Next saturday will be a meeting which will take up these suggestions & put them to action. Calling on all Praja people to put in their suggestions now as comments to this thread
Two, traffic police are interested in enforcing lane discipline & want to know some innovative way of drilling in unselfishness & discipline in the people.

On the congestion improvement my suggestions are the following
1. Bible society junction redesign
2. Mantri mall Traffic improvement plan
Along with this I recommend the placement of direction signboards as per MUTCD standards given here since IRC 67 does not mention where on the road the signboards must be placed. Perception response time (PRT) needs to be considered before placing such signs.
For lane discipline following are the steps
1. Paint consistent lanewidths regardless of wether it is 3.75m or 3.3m
2. Allocate any extra space not fittign into the lanes to pedestrians or hatch it off with physical barriers so it is not usable to vehicular traffic.
3. We need to structure & roll out the DDC program in a better way so information can reach more people.
Each of you should identify a stretch in your area & provide solutions so it can be forwarded to Mr Saleems office.

Abstracting the above solutions to a generic theme I would say intersection spacing is the root of these problems. Due to the amount of traffic going in & out, a mall/business park driveway shuld also be treated like a turn & not a low volume driveway. In both the case of Mantri mall & Bible society merge the weaving to the extreme corner over a short distance is the cuse of the holdup. I can identify the 11th cross sankey lake east road to the new BEL road CV raman road junction as another such problem fitting in this theme.

In case of this junction the small red markers denote the closed roads. The traffic should merge into CV raman road at either one of the Big blue marked roads depending on the size of the backup at peak hours. Farther the better.
This access management paper (table 1 specfically) has good detailing on intersection spacing. Hence it follows that if you take an arterial divided road in your neighbourhood which has a speed limit between 40 & 60 kmph. You could identify roads which joind at lesser than 400 meters from a right turn either into another street or into a high volume driveway. The solution will more or less fall into the following 2.
1. Seal the road or driveway to prevent traffic from entering the road. Bollards can be used to allow pedestrians & cyclists to use the intersection & prevent only motor vehicles.
2. Put in a hard divider running along the outermost lane lane preventing the cross over to an inside lane for the turn, the traffic will skip the immediate junctions & take the turn at the next junction or make a U turn & come back to the skipped junction/driveway
In case of the Bible society & Mantri Mall the second solution has been chosen because the traffic will need to anyway flow usefully forward without weaving & merging. In case of the New BEL road junction option 1 can be used. SO pick your problem junction & see whether you want to recommend option1 or option 2
CIL and J C Nagar Junctions on Jaymahal Rd!

My 2 suggestions for Jaymahal Road would be:
1. CIL Junction
2. J C Nagar Main Rd
View J C Nagar Main Rd Junction in a larger map
Suggestions/Demand
1. These junctions need Magic Boxes for Right Turns from both CIL and JC Nagar Main Rd to Jaymahal Rd and Vice-Versa.
2. Provision for Pedesterian Crossings at both junctions.

I think JC Nagar main rd junction fits the intersection spacing pattern. I would think option 2 of allowing only straight movement from there towards cantt or Nandidurg road is feasible. That junction has a small roundabout where waiting traffic chokes the nearby intersection during peak hours
Vehicles going towards Mekhri circle would have to take right at CIL road juction from one of the internal roads behind the TV station. Vehicles coming from cantt or Nandidurg rd going to Jayamahal will have to take U turn at CIL junction. CIL jn will need some fixing to alow this as the road width now is too small for a U turn(for now take a right & go into the layout from behind the TV station. Land for widening has been acquired already, post widening it will need a dedicated turn lane or an underpass like you have suggested.

The Kadubisanahalli underpass opened today. Some minor work, and the road surface seems to be pending.. But, it was open to traffic..
Wonder why the flyovers, which started construction atleast one year in advance of the underpass is still not done!
