What you’ll learn

  1. Frame the marketplaceExplain why ride-hail supply and demand are local, time-dependent, and constrained.A request is a changing marketplace job, not a simple nearest-car lookup.
  2. Build a dispatchCompare ETA-aware, first-dispatch, and batch-matching decisions.Dispatch weighs pickup time, acceptance, future opportunities, and responsiveness.
  3. Balance the marketDescribe surge as feedback that changes rider demand and driver supply.Dynamic price is a control input with delayed responses and side effects.
  4. Evaluate the systemAssess matching by completed outcomes and explicit tradeoffs.A useful algorithm is judged by the full pickup loop and by whose costs it counts.

Questions this course answers

Why is the closest driver not always the best match?

Dispatch compares estimated arrival and other constraints, not only straight-line distance.

Put the basic surge feedback loop in order.

Surge is a feedback input whose effects arrive through rider and driver responses.

What is a benefit of batch matching?

A short batch window lets the system evaluate combinations rather than only the first available choice.

Why should a platform measure completed pickups instead of only initial assignments?

The customer experience continues after the algorithm selects a driver, so evaluation must include the full chain through pickup and trip start.

Why is there no single best matching objective?

Matching rules encode tradeoffs among riders, drivers, network effects, and policy goals, so success depends on which outcomes the system values.
