Just a reminder to all the readers, the BRT as a concept has already being implemented in Pune City. It was the first BRT corridor in India and its sucessfully running in 2 corridors namely Katraj- Swargate and Hadapsar- Swargate, with 6 more corridors being planned and under design.
There were indeed few snags even in Pune, but yet the project went ahead and currently stands as in "running" condition.
On second thoughts, a Ultra low floor Tram can be implemented instead of a BRT. in the same BRT corridor, its both cheaper than a Metro rail and monorail, as well as better blended in road traffic than normal rail and metro transport. Several cities and towns in Europe and Asia successfully run Hi-Tech Ultra low-floor Trams.
In fact a few of "successful" BRT corridors over a period of time ultimately have in fact moved either to Light Rail Systems or Ultra Low Floor Trams.
The closeness of the low floor tram to the rail track and road surface as well as the usage of a overhead pantograph instead of a third rail as in a Metro rail makes is more suitable to blend easily in city trafic along other modes of road transport.
Moreover one low-floor tram can in fact take the load of 4 buses in a single go.
Better way out is to implement the HiTech Low Floor Trams in all existing BRT corridors as the concept of BRT as unimplementable in dense traffic locations like in India.
