PersistentUpdate

Description

The PersistentUpdate service allows a user to override aspects of the network. The overrides can be done on a per-road type, at a specific point or at a specific segment. The persistent update is valid only for a specific data source and may not be valid after a data update.

Using persistent updates to make these types of modifications, you have the ability to:

  • Exclude a point
  • Exclude a segment
  • Set the speed of a point, segment, or road type
  • Change (increase or decrease) the speed of a point, segment, or road type by a value
  • Change (increase or decrease) the speed of a point, segment, or road type by a percentage
  • List persistent updates
Note: Since persistent updates are changes made on a system-wide basis for routing data and all updates will persist, they should be used with caution. The response from the REST service will be a success message. When a request contains invalid query parameters in the GET URL or an invalid payload for POST, a cumulative error response will be returned in a JSON array. The value node in the response JSON is deprecated. For error checking, only the errors node should be utilized.
