Lane ki asli capacity: kitni gaadiyan nahi, kitne log
Do lane barabar chaudi hain. Ek mein sirf car, doosri mein bus. Ek ghante mein kaunsi zyada log aage pahunchaayegi?
Socho pehle… phir dekho jawab
Lane ki person-capacity = ek ghante mein guzarti gaadiyan × har gaadi mein log. Bus kam guzarti hai, par har bus mein log bahut zyada hote hain.
Formula: log/ghanta = gaadiyan/ghanta × occupancy. Udaharan (sirf samajhne ke liye, asli maap nahi): car lane mein 1,500 car/ghanta × 1.5 log = 2,250 log. Bus lane mein 60 bus/ghanta (har minute ek) × 50 log = 3,000 log. Isi wajah se engineer 'person throughput' dekhte hain.
Survey ka sach: pehle National Household Travel Survey (NSS 80th round, July 2025-June 2026, lagbhag 20 lakh log) ke mutabik kaam par 42.6% log two-wheeler se, 28.3% paidal, 10.7% cycle se, 6.7% bus se aur 3% car se jaate hain. Indian Express ke hisaab se sirf 9% public transport lete hain.
Cause-effect: jab bus kam aur dheemi ho, toh log two-wheeler khareedte hain; sadak par gaadiyan badhti hain, jam badhta hai, aur bus aur dheemi hoti hai. Ek chakra. Jahan rail hai, wahan log use karte hain: Maharashtra mein 20.7% shehri kaamkaaji metro/suburban rail lete hain.
So what: 1 km se lambi shehri yatra mein 21.7% auraten bus leti hain, aadmi 6.9%. Bus ki frequency aur suraksha ka seedha asar auraton ke kaam par pahunchne par padta hai.
Ghar pe try karo
Apne udaharan banao: ek auto lane (3 log/auto, 800 auto/ghanta) aur ek cycle lane (1 log/cycle, 2,000 cycle/ghanta, sirf udaharan). Har lane ke log/ghanta nikaalo aur bus lane ke 3,000 se tulna karo.
Wow!
Har minute ek bhari bus wali ek lane, udaharan mein, car wali lane se zyada log le jaati hai!
