“A metro is an urban guided transport system, mostly on rails, running on an exclusive right-of-way without any interference from other traffic or level crossings and mostly with some degree of drive automation and train protection. These design features allow high capacity trains to run with short headways and high commercial speed. Metros are therefore suitable for the carriage of high passenger flows.”
Metros are major capital assets of cities. Urban Metro Projects have proven to be very useful in decongesting large cities. There are around 148 cities around the world had a metro system with nearly 540 metro lines, 9,000 stations and 11,000 kilometres of line infrastructure by the end of 2013. The world’s metro systems carry 150 million passengers per day, moving daily the rough equivalent of Bangladesh’s entire population, the 8th most populated country in the world!
