Event behavior for route reassignment

适用于 Location Referencing 许可。

During route reassignment, events are impacted in the edit activity areas, and upstream and downstream of the reassignment, depending on the configured event behavior for each event layer.

注：

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.

注：

对于已选中“下游重新校准”的任何 LRS 路线编辑，配置的校准事件行为将应用于下游弧段。 可通过查看 LRS 事件属性查看配置的事件行为。

The following sections detail the results of executing the Apply Event Behaviors tool on event features after a corresponding route edit.

Route reassignment scenario

This route reassignment scenario involves two routes. A portion of Route1 is reassigned to Route2.

Stay Put behavior

Although the geographic location of the event outside the reassign region is maintained, the measures can change. The event can also split if it crosses the reassign region. Portions in the reassign region are removed.

Move behavior

Although the measures of the event are maintained, the geographic location can change.

Retire behavior

Events intersecting the reassignment region are retired.

Snap behavior

Although the geographic location of the event is maintained by snapping to the route that it was reassigned to, the measures can change. The event can also split if it crosses the reassign region.

Upstream and downstream sections

Route editing impacts upstream and downstream sections differently.

The following diagram shows the upstream and downstream section for the route reassignment scenario:

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

Behavior	Events upstream reassignment	Events intersecting reassignment	Events downstream reassignment
Stay Put	No action	Retire event. Line events crossing the edit section are split and the original event retired.	If route calibration is changed, the recalibrate event behavior is applied; otherwise, no action.
Move	Shape regenerated, if needed, to new location of route measures	Shape regenerated to the new location of route measures.	If route calibration is changed, the recalibrate event behavior is applied; otherwise, no action.
Retire	No action	Retire event. Line events crossing the reassignment region do not split.	If route calibration is changed, the recalibrate event behavior is applied; otherwise, no action.
Snap	No action	Geographic location (x,y) is maintained. The event is migrated to the reassigned route. Line events crossing the edit section are split.	If route calibration is changed, the recalibrate event behavior is applied; otherwise, no action.

注：

• 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 the events downstream of the edited portion of the route.
• Since the LRS is time aware, edit activities such as reassigning a route time slice routes and events.

Detailed behavior results

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

Stay Put behavior

If the reassignment is set to occur on 1/1/2005 with target values of 0 to 5 and Recalibrate route downstream is chosen, this has the following effects:

• Event1 is represented by two time slices. 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>, with measures from 0 to 5 that stay in the same location geographically but have the new measures from Route1.
• Event2 retires to maintain geographic location.

Event1	Route1	1/1/2005	<Null>	0	5	No Error
Event2	Route1	1/1/2000	1/1/2005	7	10	No Error

Move behavior

If the reassignment is set to occur on 1/1/2005 with target values of 0 to 5 and Recalibrate route downstream is chosen, this has the following effects:

• Event1 is represented by two time slices. 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> with measures from 0 to 7 that move geographically to maintain the original event measures. This new time slice only partially locates since the event time slice has measures from 0 to 7, but the underlying route only has measures from 0 to 5. The event has the same measures but different geometry in the new time slice.
• Event2 is represented by two time slices. There is a time slice from 1/1/2000 to 1/1/2005 with the original measures from 7 to 10, and a time slice from 1/1/2005 to <Null> with measures from 7 to 10 that move geographically to maintain the original event measures. This new time slice does not locate since the event time slice has measures from 7 to 10, but the underlying route only has measures from 0 to 5. The event has the same measures but different geometry in the new time slice.

Snap behavior

If the reassignment is set to occur on 1/1/2005 with target values of 0 to 5 and Recalibrate route downstream is chosen, this has the following effects:

• Event1 is represented by two time slices. 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> with two event records. The first Event1 event record after reassignment has measures from 0 to 5 that snap to the new measures from Route1; and the second event record has measures from 0 to 2 that snap to the new measures of Route2.
• Event2 is represented by two time slices. There is a time slice from 1/1/2000 to 1/1/2005 with the original measures from 7 to 10, and a time slice from 1/1/2005 to <Null> with measures from 2 to 5 that snap to the new measures of Route2.

Detailed behavior results on routes in a line network with events that span routes

The following sections detail how event behavior rules are enforced when routes on a line in a line network are reassigned.

Stay Put behavior

The routes are active from 1/1/2000, and if the reassignment is set to occur on 1/1/2005 from measure 25 on Route3 to 48 on Route4 and Recalibrate route downstream is not chosen, this has the following effects:

• Reassignment is used for merging Route3 and Route4 to create a new route, Route3A.
• Event1 is represented by two time slices. There is a time slice from 1/1/2000 to 1/1/2005 with the original measures from 0 on Route1 to 30 on Route3, and a time slice from 1/1/2005 to <Null> with measures from 0 on Route1 to 22 on Route2, as it stays the same geographically. The portion of the event on Route3 is retired since there is no Route3 to build the event shape on any longer.
• Event2 retires. as the event is completely within the reassigned portion. There is no longer a Route3 or Route4 on which to build the event shape.

Event2	1/1/2000	1/1/2005	Route3	Route4	30	48	Route Not Found

Move behavior

The routes are active from 1/1/2000, and if the reassignment is set to occur on 1/1/2005 from measure 25 on Route3 to 48 on Route4 and Recalibrate route downstream is unchecked, this has the following effects:

• Event1 is represented by two time slices. There is a time slice from 1/1/2000 to 1/1/2005 with the original measures from 0 on Route1 to 30 on Route3, and a time slice from 1/1/2005 to <Null> with measures from 0 on Route1 to 30 on Route3, but since Route3 has been reassigned, the shape can’t be built in that location. In the new time slice, the event has the same measures but different geometry.
• Event2 is represented by two time slices. There is a time slice from 1/1/2000 to 1/1/2005with the original measures from 30 on Route3 to 48 on Route4. The second time slice, from 1/1/2005 to <Null>, has measures from 30 on Route3 to 48 on Route4, but Route3 and Route4 have been reassigned, so there is no shape for this event.

Event2	1/1/2005	<Null>	Route3	Route4	30	48	Route Not Found

注：

Event2 exists after the Apply Event Behavior tool is run but has no shape.

Retire behavior

The routes are active from 1/1/2000, and if the reassignment is set to occur on 1/1/2005 from measure 25 on Route3 to 48 on Route4 and Recalibrate route downstream is not chosen, this has the following effects:

• Event1 retires since it is located in the reassigned region.
• Event2 retires since it is located in the reassigned region.

Snap behavior

The routes are active from 1/1/2000, and if the reassignment is set to occur on 1/1/2005 from measure 25 on Route3 to 48 on Route4 and Recalibrate route downstream is unchecked, this has the following effects:

• Event1 is represented by two time slices. There is a time slice from 1/1/2000 to 1/1/2005 with the original measures from 0 on Route1 to 30 on Route3, and a second time slice from 1/1/2005 to <Null> with two event records. Because the reassignment took place in the middle of the event, it splits. The first Event1 record after reassignment has measures from 0 on Route1 to 22 on Route2, while the second Event1 record has measures from 25 on Route3A to 30 on Route3A. Both events stay in the same location geographically, but the second event snaps to the new route at the location, Route3A.
• Event2 is represented by two time slices. There is a time slice from 1/1/2000 to 1/1/2005 with the original measures from 30 on Route3 to 48 on Route4, and a time slice from 1/1/2005 to <Null> with measures from 30 on Route3A to 48 on Route3A. The event stays in the same location geographically, but snaps to the new route at the location, Route3A.
