As could be seen in this map, it works for bicycles. (Cycle lane going from NW to the centre of the junction)

In this case however, it is designed to provide a 'protected' lane for cyclists who wish to go straight from cars who wish to go go left.

 it works for bicycles

Bicycles are not motorized and unsafe to ply on standard lanes. The only reason we go out of the way for them is because they are non polluting and have health benefits in the long run. Why would one need a special lane for motor vehicles when they have none of bicycle benefits and can use the standard lanes?

 Not for benefit of any kind of vehicle in particular, but to help to ease traffic in general. If a lane specified for them , we are providing a passage, who otherwise are obstruction for 4 wheelers. ps: this works if lane descipline is observed, else nothing will work, be it any type of road signs.

who otherwise are obstruction for 4 wheelers

How are they an obstruction? What are the causes of obstruction? Are we removing the cause by adding an extra lane and segregating them? If they can stick to their special lane why cant they stick to the normal lane? I dont think you have read the link to the other thread and understood/agreed the need for lanes and the role in traffic movement as i have elucidated

This help 2 wheelers to come at front and stand in que.

That statement is an oxymoron. They already jumped the queue when they came in front. Do read this blog on lanes. Might help answer some questions. 

Why is the signal so different from rest of the road? What bad habits we cultivate! And want to legitimize it also. Akrama only.

I submit that I did not go through full thread link which IDS has given. But we see scene as shown in image below . Hence thought this would be approach. More thoughts have to go in here. Isn't it?I am not good in illustration and this is not only scenario. Probably we should consider 2 wheeler, 3 wheeler and more.. IDS, thanks for your inputs, and keep digging more, Samudra Mathana gives Amrutha , lets hope for a solution and approach it, in objective way, as we do now. What say?

By the way, how is progress in this work (Not related to this thread though)?

 I was going through Shastri's blogs. One of which he posted in 2006, I think still to be considered. I am for privatizing traffic regularization and and through scientific way of crowdsourcing ( well designed system, where is certain people are trained, certified and re-certified to do the job). Shastri, good posts ! It paid for me to dig into your old blogs. And I am impressed even by this article, about driver profiles, even today, there is no change in their profiles, perfectly maintained. But Shastri, It is the time to add few more profiles, Volvo drivers, Rich(Poor drivers who drive the vehicles of the rich) and finally minister's drivers (courtesy: Bachchegowda). On lighter note, I feel US and UK should outsource drivers too, we have huge potential.

 Also I feel more markings needed on road, which guide drivers clearly. I am happy with markings done in Hosur Road near signals but it has be improved further, as shown below. Also each lane should have speed marks. Once this is done, I also feel lane breakers (who travel in much deviated speed in the lanes should be fined using interceptors, not only for high speed, but also for low speed).

Note: As usual this is very rough picture, should be done professional way :)

Conceptually, urban planners design dedicated lanes to encourage a shift from motorized private transportation to either motorized public transportation (buses) or non-motorized private transportation (bicycles). The use of HOV/carpool lanes is an exception to that (and a controversial one at that) since it could be considered as a more palatable version of the automobile.

By providing special infrastructure to the 2W you turn the concept of dedicated lanes on its head. In your most recent illustration [which I redrew in the pics below with a car (maroon box), auto (green trapezoid), bus (orange box) and 2Ws (red boxes)]...

...what you are essentially conveying is that a bus (orange box) can be 'queue-jumped' by the 2Ws (red boxes). Why would anyone seeing that want to take the bus?

On practical grounds too, if you were to add a safe 2W lane to each directional lane, wouldn't we need to rewiden our rewidened, widened roads!

Having said all this though, your illustration is excellent... when it is designed for bicycles (green boxes) :)

TM,

In your illustration/s above, bicycle lanes are displayed amidst lanes for motorized traffic with no protection. Traffic conditions being what they are in our cities, I think bicycle lanes need to be physically separated from all other traffic, & this is best done by moving them to the edges of streets to facilitate barricading & misuse by scooterists & motorcycles.

@ Naveen, yes that's probably the best way to enforce exclusive use of the bicycle lane until (maybe, just maybe) one day driver behavior improves to the point that we don't need that physical separation.

I have a question though. With the bike lane on the inside edge of the street, do they get a dedicated red/green light at the intersection (i.e. how do they travel safely if they are going straight?)? Or are they considered as pedestrians vis-a-vis the signalling pattern at the intersection? Anyone have info/observations from the bicycle lanes in Delhi?

Why should we differentiate within two wheeler sector, specially "near signal" (which is core of topic)?  Is that just because motorized 2-wheelers use fuel and go with higher speed? Are they dangerous drivers than auto/cab/bmtc? Help me understand.  From practical perspective and safety perspective, it would be group all two wheelers in a lane, either sides or center and separating them from 4 wheelers with a barricade. To be more precise, categorization should be based on space they occupy in road, easy passage through signals. This would smoothen traffic. I agree with warning that if two wheelers allowed to 'que-jump', its like discouraging discipline and public transport. But we should analyze the impact, in terms of traffic management , though we support public transport . I am afraid, I am getting biased to 4 wheelers, but no worries if it helps overall traffic situation near signals.

Motorized two-wheelers (& lightweight motorized three wheelers, such as autos) are known to be the most manoeverable of all vehicles, & hence, chaos & congestion on streets is aggravated by their presence since they can easily misuse pedestrian & bicycle facilities, go in between 4-wheelers, etc. It is for this reason that some world cities have banned them. None of the types of 4-wheeled vehicles are as manoeverable, by design.

Bicycles, cycle rickshaws, hand or bullock-driven carts depend on muscle power from humans /animals, which is several times smaller & weaker than the power available at a driver's disposal on 2, 3 or 4 wheelers.

Thus, categorization should never be based on the spaces they occupy on streets, but on how they are driven. It will be unfair if such vehicles are grouped & forced to compete for movement & road space with motorized vehicles, as is currently happening here. This also explains why bicycles are a vanishing breed in bangalore since the risks associated with bicycle-driving without a continuous network of secure infrastructure is very high, unlike most cities abroad.
