Event behavior for route calibration

Disponible avec la licence Location Referencing.

When route calibration occurs, events are impacted, depending on the configured event behavior for each event layer.

Remarque :

Events are not updated until the Apply Event Behaviors tool is applied after route edits. If you are using conflict prevention, you are prompted to run Apply Event Behaviors before posting can be completed.

Calibration can occur on a route when one or more calibration points are added, edited, deleted, or when recalibration downstream is selected for LRS route editing tools.

Calibration point changes can be made using Location Referencing tab calibration tools, by creating or editing calibration points using create features in ArcGIS Pro, by using Apply downstream recalibration in Location Referencing route editing tools, or by checking the Record calibration changes for event location updates option when running the Generate Routes tool.

Route calibration scenario

This route calibration scenario involves one route with two existing calibration points. A calibration point at existing measure 10 is changed to 15, resulting in recalibrated measures downstream.

Stay Put behavior

The geographic location of the event is maintained; the measures can change.

Move behavior

The measures from the event are maintained; the geographic location can change.

Retire behavior

The geographic location and measures are maintained; the event retires.

Upstream and downstream sections

The following table details how the calibration editing activity impacts upstream and downstream events according to the configured event behavior:

Behavior	Events upstream of calibration point edit	Events crossing calibration point edit	Events downstream of calibration point edit
Stay Put	Measures on an event update to maintain the geographic location if the event crosses the section between the edited calibration point and the nearest upstream calibration point.	Measures on an event update to maintain the geographic location of the event.	Measures on an event update to maintain the geographic location of the event. If the event crosses the section between the edited calibration point and the nearest upstream calibration point, measures update due to calibration point values changing.
Move	The event polyline shape updates to the new location of measures on the route if the event crosses the section between the edited calibration point and the nearest upstream calibration point.	The event polyline shape is updated to the new location of measures on the route.	The event polyline shape is updated to the new location of measures on the route if crossing a section of the route with a calibration point with measures is updated.
Retire	The event retires if the event crosses the section between the edited calibration point and the nearest upstream calibration point.	The event retires; line events crossing the edited calibration point are not split.	The event retires if the event crosses a section of the route with a calibration point with measures updated.

• Point events follow the same behavior as line events but don't need to be split.
• If the option to recalibrate route downstream is selected, calibrate route event behaviors are applied to the events downstream of the edited portion of the route.
• Since the LRS is time aware, edit activities such as calibrating or retiring a route result in time sliced routes and events.
• If the route is calibrated the same day that it's created and the event behavior for calibrate is set to retire, the events are deleted and not retired.

Detailed behavior results

The following sections detail how event behavior rules are enforced when a route is calibrated.

Stay Put behavior

A calibration point is added to the route at existing measure 10 with an effective date of 1/1/2000. The added calibration point has a new measure of 15 with recalibrate downstream applied and an effective date of 1/1/2005. This calibration has the following effects:

• Event1 is represented by two time slices because the route recalibrated to the nearest upstream calibration point with measure 5. There is a time slice from 1/1/2000 to 1/1/2005 with the original measures from 0 to 7, and a time slice from 1/1/2005 to <Null> that stays in the same location geographically but has the new measures 0 to 9 of Route1.
• Event2 is represented by two time slices because it crosses the location where the recalibration took place on the route. There is a time slice from 1/1/2000 to 1/1/2005 with the original measures from 7 to 15, and a time slice from 1/1/2005 to <Null> that stays in the same location geographically but has the new measures 9 to 20 of Route1.
• Event3 is represented by two time slices because it crosses the location on the route where it was recalibrated downstream. There is a time slice from 1/1/2000 to 1/1/2005 with the original measures from 15 to 20, and a time slice from 1/1/2005 to <Null> that stays in the same location geographically but has the new measures 20 to 25 of Route1.

The route measure is 10; add a calibration point with measure 15 and recalibrate downstream.

Event3	Route1	1/1/2005	<Null>	20	25

Move behavior

A calibration point is added to the route at existing measure 10 with an effective date of 1/1/2000. The added calibration point has a new measure of 15 with recalibrate downstream applied and an effective date of 1/1/2005. This calibration has the following effects:

• Event1 is represented by two time slices because the route recalibrated to the nearest upstream calibration point with measure 5. There is a time slice from 1/1/2000 to 1/1/2005 with the original measures from 0 to 7, and a time slice from 1/1/2005 to <Null> that retains the original event measures from 0 to 7, but for which the geographic x,y location moves to the new location of those measures on the route because the route recalibrated to the nearest upstream calibration point with measure 5.
• Event2 is represented by two time slices because it crosses the location where the recalibration took place on the route. There is a time slice from 1/1/2000 to 1/1/2005 with the original measures from 7 to 15, and a time slice from 1/1/2005 to <Null> with the same measures from 7 to 15 that move to their new location on the route.
• Event3 is represented by two time slices because it crosses the location on the route where it was recalibrated downstream. There is a time slice from 1/1/2000 to 1/1/2005 with the original measures from 15 to 20, and a time slice from 1/1/2005 to <Null> with measures from 15 to 20 that move to their new location on the route.

Retire behavior

A calibration point is added to the route at existing measure 10 with an effective date of 1/1/2000. The added calibration point has a new measure of 15 with recalibrate downstream applied and an effective date of 1/1/2005. This calibration has the following effects:

• Event1 retires because the route recalibrated to the nearest upstream calibration point with measure 5.
• Event2 retires because it crosses the location where the recalibration took place on the route.
• Event3 retires because it crosses the location on the route where it was recalibrated downstream.
