Metro Alone May Not Be Enough

From today's The Hindu (link) :

Traffic engineering expert M.N. Sreehari points out that Namma Metro can decongest city roads only by just 25 per cent, and that too along its corridor. Only when this corridor is networked with other modes of public transport can visible change occur on Bangalore's roads, Prof. Sreehari said.

Prof. Sreehari pointed out that Namma Metro Phase 1 and Phase 2 will not be sufficient to cater to the growing demand for public transport in Bangalore. Along with other modes, more Metro lines should criss-cross the city as early as possible to reduce the pressure on roads.

25% of traffic along its corridor.  And the corridor is pretty narrow.

So those London dreams won't come true it appears (from Times Of India 2003 - Will Metro solve city's transport woes):

Bangalore city is looking for a mass transportation system that can claim to be swift, ease pollution and congestion. The best answer to the city's various traffic woes appears to be the Metro Rail.

The London Metro, which spans the entire city, connects all important spots and even the airport. But travel is comfortable and takes just a few minutes, enhancing the quality of life. A majority live in the suburbs,where housing is inexpensive. For them, the Metro is the lifeline. Driving through London takes hours, which is also true of Paris, New York, Washington and other major cities, point out experts. 

ToI omitted the fact that the London Metro is actually called 'London Underground'.

We were sold a defective good.  And now there will be a clamour for more - mono rail, high speed rail etc... - feeder services for a stupid metro system.
