Optimise multi-vehicle, multi-stop delivery plans (VRP). Provide vehicles (id, start/end, capacity, skills, time_window), jobs (id, location, service_s, delivery/pickup, skills, time_windows) and/or shipments (pickup+delivery pairs that ride the same vehicle). Costing "auto", "truck", "bicycle", "pedestrian" or "motor_scooter" (cargo-bike and courier fleets welcome): with a truck profile (dimensions + ADR declaration, as in route), the travel-time matrix respects dimensional and dangerous-goods restrictions, so every optimised route is truck-legal. Returns a summary, unassigned tasks and per-vehicle routes with ordered steps (arrival_s/duration_s in seconds, distance_m in metres). Fair use: at most 200 unique locations per problem, and no wider than the routing engine's matrix span (1,500 km on the hosted endpoint for motor costings, 400 km stock on a self-host). Past that, cluster the stops with cluster and optimise each group, or submit the whole problem to the asynchronous lane with submit_optimise_job (2,000 locations). Optional territories are named polygons ([{id, polygon}], GeoJSON [lon, lat] rings, LONGITUDE FIRST) that bound who serves what: a vehicle listing territory_ids may serve a task only if that task sits inside at least one of the territories it names, while a vehicle listing none is unrestricted and may serve anything, inside a round or outside every one. The response's territories block says which vehicle was eligible for what and names any task no vehicle could take. A vehicle may also declare reloads {max_trips 2-5, reload_time_s, depot?} to return to a depot, reload and go out again — the tipping round. It needs a time_window, because the shift is what gets split: it is cut into that many consecutive non-overlapping windows separated by the reload time, each trip carrying the vehicle's FULL capacity and task caps. That split is fixed BEFORE the solve, so the plan is conservative and never optimistic — it cannot put a lorry in two places at once — but it is an approximation: a trip that finishes early cannot lend its spare time to the next, so stops can come back unassigned that a truly sequential model would have served, and max_trips is a budget rather than a prediction (ask for five on a shift that supports three and every window shrinks to a fifth). Read the returned reloads block before quoting arrival times, and re-plan after each tip with replan_routes for the tighter answer. relax_if_unassigned {time_windows_by_s?, allow_overtime_s?} re-solves ONCE with those relaxations if the first plan left work unassigned, and the relaxation block says honestly which plan came back: at most one second solve, never beyond the caps stated, and the relaxed plan is returned ONLY if it assigns more work than the first. Breaks are never widened — a driver's rest is not a preference to trade for a fuller van — and neither are capacities, skills, territories or task caps; only time windows move. It bills as two solves when the second one runs. Always check relaxation.relaxed_plan_used before telling anyone the day fits: a plan produced under relaxation has had promises moved. emissions {vehicle_category, fuel, euro_standard} annotates the plan with the clean-air zones its own stops sit in and what this vehicle pays in each; add avoid_zones: true to steer the travel-time matrix out of them, which changes the plan itself. Territories, reloads, relaxation and zones are computed by the MapMap gateway; without one configured the tool refuses rather than returning a plan that quietly ignored them.
Input schema
| Property | Type | Required | Description |
|---|---|---|---|
| avoid_zones | boolean | null | no | Keep the optimisation's travel-time matrix out of every zone the declared vehicle would be charged or banned in. Requires `emissions`. |
| costing | any | no | Costing model for the travel-time matrix: "auto" (default), "truck", "bicycle", "pedestrian" or "motor_scooter". |
| emissions | any | no | The fleet's emission declaration, for UK clean-air / low-emission zone assessment. On its own it annotates: the response's `zones` block names every zone containing one of the problem's own locations and what this vehicle would pay there. With `avoid_zones` it also steers the internal travel-time matrix away from those zones, so the plan itself changes. |
| jobs | array | no | Single-stop jobs (at least one job or shipment overall). |
| relax_if_unassigned | any | no | Re-solve ONCE with these relaxations if the first solve leaves work unassigned, and say honestly which plan came back. At most one second solve, never beyond the caps you state, and the relaxed plan is returned only if it assigns MORE work than the first — giving away constraints for nothing is strictly worse than not giving them away. Breaks are never widened, nor are capacities, skills, territories or task caps: only time windows move, and only by the stated amounts. Bills as two solves when the second one runs. |
| shipments | array | no | Pickup+delivery pairs. |
| territories | array | null | no | Fleet territories: named polygons that bound which vehicle may serve which stop, referenced by `vehicles[].territory_ids`. These are request data — caller-drawn rounds, validated per call and never stored. Nothing to do with clean-air zones or with the offline map packages of the same word. |
| truck | any | no | Truck profile (dimensions + ADR declaration). Requires costing "truck"; the travel-time matrix then respects dimensional and dangerous-goods restrictions, so the whole plan is truck-legal. |
| vehicles | array | yes | The fleet (at least one vehicle, each with a start and/or end). |
