The 'rail transit' (metro/light rail) in Indian cities has the key advantage over bus transit of:
Choose the correct answer
Lower initial capital cost than bus
High capacity (1000–2500 pax/train), dedicated ROW reliability, speed, and energy efficiency — viabile for demand > 20,000 PHPDT
Metro can operate on existing road surface
Metro requires no operating subsidy
Correct Answer
B. High capacity (1000–2500 pax/train), dedicated ROW reliability, speed, and energy efficiency — viabile for demand > 20,000 PHPDT
Why is this the answer?
Mass rapid transit (MRT): advantages over bus: (1) Higher capacity (trains 1000–2500 passengers vs bus 50–80); (2) Faster (dedicated ROW, no traffic); (3) Energy efficient (per passenger-km); (4) Reliable (schedule not affected by traffic); (5) Reduces road congestion; (6) Trigger TOD (transit-oriented development). Disadvantages: very high capital cost (Rs 200–500 cr/km underground), fixed route, high operating cost per seat. Viable for demand > 20,000 PHPDT.
