How many drivers would a new ride-sharing service need to launch in Austin?
How to approach it
Turn expected demand at peak into drivers needed, since peak hours, not daily averages, set the fleet size.
How a strong answer opens
“Peak demand, not the daily average, sets how many drivers we need. So I'll estimate rides in Austin's busiest hour, take our target share, and divide by rides per driver per hour.”
Outline of a strong answer
Try answering out loud for a few minutes before you open this.
- Clarify launch target: share of the ride-hail market
- Estimate total ride demand in the city at peak hour
- Apply the target market share
- Rides per driver per hour
- Drivers needed at peak, plus a buffer for drivers who log off
- Convert to total drivers given hours each drives per week
Where this question usually goes wrong
Dividing daily rides by 24, which badly understaffs the evening peak, or forgetting that each driver works only some hours a week.
