Estimate the number of travelers in India per day.

Types of mass travels: Interstate, Inter district, Intra district. Modes of transport: Flights, Trains, Buses, Private Transport. Frequency of trasport. Avg no of travellers. Total no. of domestic travellers.

International travellers to India. 10 mn/year divided by 365 ~ 30000/day

International travellers from India ~ 30000/day

Add it all up.

Estimation:

Interstate flights: Top 10 states have an average of 6 flights per day between themselves. Top 8 & the smaller 20 have average 2 flights/day between themselves. The 20 smaller states have average 1 flight/da between themselves. ~ 140 flights/day*200 average no. of passengers = 28,000

Interstate Trains: Top 10 --> average 3 trains per day. Between top10 & smaller 20 --> 2 /day. Between smaller 20 --> 1/day. ~80trains*avg of 1500 passengers = 120,000

Interstate Buses: Each state will have buses to an average of 6 neighbouring states. Each interstate segment is covered by an average of 3govt and 3 private buses. 30 states * 6 buses * 60 avg passengers = 10,800

Interdistrict trains: Average of 25-26 districts per state. Top 6 districts * avg. 1 train per day + 20 districts * avg. 3 trains per week (3/7 per day) = 15 trains per day * 1500 = 22500*30 states = 675,000

Interdistrict buses: 6 districts * 6 per day + 20 districts * 2 per day = 76 buses * 60 passengers = 4560 * 30 states ~ 135,000

Intra district buses: Average of 4 taluks/district*5 buses/day*60 passengers*30districts*30 states ~ 1,000,000

Summing it all up. ~ 2,000,000 travellers /day using mass transport + around 10% of this in private transport vehicles ~ 2,200,000 travellers/day in India
