Not all the bus services will get DDs simply due to the demand
factor, heights, etc etc. Dont think that bus services should get
DDs for the sake of doing so. It is very apparent that 3 bypasses
narrow roads, 19 already has DDs, 40, 82, 101 has low demand, hence
totally no need for DDs. For service 43, DD trials had been
conducted but apparently it isnt a viable option to have DDs on
43.
