GrabShare at the Intelligent Transportation Engineering Conference

Summary

Grab presented a technical paper on the construction of its real-time ridesharing service, GrabShare, at the Intelligent Transportation Engineering Conference in Singapore. The platform pairs passengers heading along similar routes with drivers immediately while handling network drops, volatile supply and demand, and heavy traffic conditions in Southeast Asian cities. To deliver accurate pairings, the scheduling system generates and filters through hundreds of travel time estimates for each candidate match before finalizing an itinerary. Operational teams on the ground evaluate complaints about poor matches, enabling engineers to refine the online matching systems. Over the course of one month, the service cut more than 4.5 million kilometers of driving distance and brought in over 100,000 new users within two weeks.

Takeaways

1. 1

   GrabShare's scheduling system evaluates and rejects hundreds of candidate travel time estimates for every successful ride match.

2. 2

   Engineers directly update the online matching systems in response to field analyses of passenger and driver complaints about inappropriate matches.

3. 3

   In a single month, shared journeys on the platform reduced total driving distance by more than 4.5 million kilometers.
