Duration groups

This feature is configurable via .json input, without the need for code customization.
Available for both the Marketplace app and Platform. You can find a list of all available features here.

This how-to guide assumes you already completed the get started with vehicle routing tutorial.

Field name	Required	Data type	SI Unit	Defined on	Example	Configurable via `defaults`
`duration_groups`	No	`array` of `duration_group`	NA	input	`{"duration_groups": [{"group":["foo", "bar"], "duration": 200}]`	➖

duration_group

Field name	Required	Data type	SI Unit	Description	Example
`group`	Yes	`array` of `string`	NA	Stop IDs contained in the group.	`{"group": ["foo", "bar"]}`
`duration`	Yes	`int`	`seconds`	Duration to add when visiting the group.	`{"duration": 5}`

Duration groups allow you to define an overhead duration that is added to the stops' regular duration each time a stop of the group is approached from a stop that is not part of the group. Duration groups are used with the duration_groups feature which defines an array of duration_group. Each duration_group holds a group (array of string) and a duration (int) in seconds.

Here is an example defining duration groups. A sample output obtained after solving the problem is also shown.
