Talking about uber car-based rides and not scooters, public transit, or helicopter.
This is # of rides per day.
Estimate the # of uber riders x their average number of rides per day. --- (a)
Splitting (a) by power users, normal users dormant users.
Estimate the volume of each of the above user types and count their rides/day separately.
US population = 300M
Target Uber audience in the range 15-65, with average life expectance of 80 years.
Thus, the target user count 50/80x300M = 190M
Assuming 70% of these users actually use Uber → 130M users
Based on my experience seeing users, 20% of users, in general, tend to be power ridesharing user, they use it atleast 1 time a week.
60% are normal users - Use it atleast 1 time a month
20% are dormant users use it once every quarter,
26M power → Daily rides → 26M/7 rides per day → 3.7M rides/day
26M casual users → 26M/90 rides per day → 0.2M rides/day
78M normal users → 78M/30 rides per day → 2.6 M rides/day
Thus total rides per day → 3.7M + 0.2M + 2.6M ~6.5M rides per day
Any feedback on my approach and assumptions?
