HARD
Design a Ride Matching Algorithm
Design the core matching algorithm for a ride-sharing service that optimizes driver-rider pairing.
Estimated Time: 45 minutes
#Matching#Geospatial#Optimization#Real-time
Solution Overview
Use geospatial index for nearby driver lookup. Implement scoring function considering distance, ETA, driver rating, and ride type.
Hints to Get Started
1
Single vs batch matching
2
Handling driver rejections
3
Pool ride matching complexity
Algorithm
Hungarian algorithm for batch matching, greedy for real-time
Matching Factors
- •Distance to pickup
- •Estimated arrival time
- •Driver rating
- •Vehicle type match
- •Driver direction
