# One to many routing
Computes the minimal duration from one place to many or vice versa.
The order in the response array corresponds to the order of coordinates of the \`many\` parameter in the query.

`GET /api/experimental/one-to-many-intermodal`

## Query parameters

- `one` string, required
- `many` string[], required
- `time` string, date-time
- `maxTravelTime` integer
- `maxMatchingDistance` number
- `arriveBy` boolean
- `maxTransfers` integer
- `minTransferTime` integer
- `additionalTransferTime` integer
- `transferTimeFactor` number
- `useRoutedTransfers` boolean
- `pedestrianProfile` 'FOOT' | 'WHEELCHAIR' — Different accessibility profiles for pedestrians.
- `pedestrianSpeed` number — Average speed for pedestrian routing in meters per second
- `cyclingSpeed` number — Average speed for bike routing in meters per second
- `vehicleHeight` number — Vehicle height for HGV routing in meters
- `vehicleWidth` number — Vehicle width for HGV routing in meters
- `vehicleLength` number — Vehicle length for HGV routing in meters
- `vehicleWeight` number — Vehicle gross weight for HGV routing in tons
- `vehicleHazmat` boolean — Whether the vehicle carries hazardous materials for HGV routing
- `vehicleHazmatWater` boolean — Whether the vehicle carries hazardous materials dangerous to water for HGV routing
- `vehicleAxleCount` integer — Axle count for HGV routing
- `vehicleAxleLoad` number — Maximum axle load for HGV routing in tons
- `vehicleTrailer` boolean — Whether the vehicle has a trailer for HGV routing
- `vehicleTopSpeed` integer — Vehicle top speed for HGV routing in km/h
- `vehicleLezAccess` boolean — Whether the vehicle is allowed to use low-emission zones for HGV routing
- `elevationCosts` 'NONE' | 'LOW' | 'HIGH' — Different elevation cost profiles for street routing. Using a elevation cost profile will prefer routes with a smaller incline and smaller difference in elevation, even if the routed way is longer. - `NONE`: Ignore elevation data for routing. This is the default behavior - `LOW`: Add a low penalty for inclines. This will favor longer paths, if the elevation increase and incline are smaller. - `HIGH`: Add a high penalty for inclines. This will favor even longer paths, if the elevation increase and incline are smaller.
- `transitModes` Mode[]
- `preTransitModes` Mode[]
- `postTransitModes` Mode[]

## Response `200`

A list of durations.
If no path was found, the object is empty.

- OneToManyIntermodalResponse — Object containing the optimal street and transit durations for One-to-Many routing
  - `street_durations` Duration[] — Fastest durations for street routing The order of the items corresponds to the order of the `many` locations If no street routed connection is found, the corresponding `Duration` will be empty
    - `duration` number — duration in seconds if a path was found, otherwise missing
    - `distance` number — distance in meters if a path was found and distance computation was requested, otherwise missing
  - `transit_durations` ParetoSet[] — Pareto optimal solutions The order of the items corresponds to the order of the `many` locations If no connection using transits is found, the corresponding `ParetoSet` will be empty
    - ParetoSetEntry[] — Pareto set of optimal transit solutions
      - `duration` number, required — duration in seconds for the the best solution using `transfer` transfers Notice that the resolution is currently in minutes, because of implementation details
      - `transfers` integer, required — The minimal number of transfers required to arrive within `duration` seconds transfers=0: Direct transit connecion without any transfers transfers=1: Transit connection with 1 transfer
