Smart Matching Engine for Ride-Sharing: Technical Implementation and Algorithms

The Smart Matching Engine for Haolo’s ride‑sharing service ingests driver and passenger orders via Kafka‑Flink pipelines into Elasticsearch, then applies multi‑stage matching—nearby search, itinerary‑based filtering using ETA, angle, distance, route‑similarity and shared‑mileage calculations—and finally ranks results with evolving pre‑sorting and algorithmic models, including PMML and deep‑learning, to optimize driver‑passenger pairing.
