The author has not talked about how those ridership estimates were made. Was there any travel demand data available?? if yes where did it come from?? I do not remember taking a travel survey ever in delhi.. I feel there should more effort made in collection of Socioeconomic data that drives mode choice and travel demand. A little bit of investment in such efforts can lead to better evaluation of alternatives. What are the SMART people sitting in Delhi University doing in terms of application of their knowledge of Econometrics and Statistics??? OR is their knowledge just for writing exams and ultra-theoretical papers????? As for bus systems, where were these experts who think BRT's are a better option doing before the decision to implement a metro system taken....
