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. Response from REST service will be a success message.
