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
