If you have faster option of taking public transport, the attractiveness of taking bus will be better and it will lure more people to take public transport.
Adding one more lane for car is pointless, but in just 2 to 3 years if you have that extra car lane, the same congestion will happen or worse as the peripheral roads connecting the highway and the local neighbourhood will remain the same.
Hence the sensible option in longer term to relieve congestion is to add bus lane.
But my concern is, who is really benefiting from this project ? For a couple of years, while in construction, we have to mind the traffic jams. Meaning, we have to go early to avoid the jams. To avoid Federal Highway, we have to pay tolls. Then after construction, we have to pay money to use it. Dont think it will be very cheap due to current economy. Then, BRT doesn't reach your doorstep, you still have to drive for a distance.
Who is benefiting? The constructor, the project awarding bodies, whoever signs the deal.......
We always end up paying for everything. At the end of the day we always turn out to be the SUCKER right!
