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
