Metro/Heavy rail capacity: 40,000–80,000 passengers per hour per direction (PPHPD). Depends on: train length (6–8 cars), car capacity (1500–2000 passengers/train), headway (2–3 minutes). Delhi Metro: 36,000 PPHPD (Phase I/II). Bus PPHPD: 4000–8000. BRT PPHPD: 4000–10,000. Metro justified above 20,000–30,000 PPHPD. LRT: 10,000–20,000 PPHPD.
