When routes are extended, events are impacted, 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：
When recalibrate downstream is chosen for an LRS route edit, the configured calibrate event behavior is applied to downstream sections.
The following sections detail the results of executing the Apply Event Behaviors tool on event features after a corresponding route edit.
Route extension scenario
The following route extension scenario involves one route and three events. The extension is at the beginning of the route.
Stay Put behavior
The geographic location of the events is preserved; the measures are changed.
Move behavior
The event measures on the route are maintained; the geographic location is changed.
Retire behavior
The geographic location and measure of the events are preserved; the events are retired.
Cover behavior
The event measures on the route are changed; the geographic location is changed to include the extended section at the beginning or end of a route.
Upstream and downstream sections
Route editing impacts upstream and downstream sections differently based on the configured event behavior.
Refer to the following diagrams to understand the upstream and downstream section for the route extension scenario:
The following table details how a route editing activity impacts downstream events according to the configured event behavior:
| Behavior | Events upstream | Events intersecting | Events downstream |
|---|---|---|---|
Stay Put | No action. | The shape is regenerated only if the event can be located using route and measures. | If the route is extended, measures are adjusted to retain x,y. |
Move | No action. | The shape is regenerated to the new location of route measures. | If the route is extended, measures move to retain x,y. |
Retire | No action. | Retire event; line events crossing the edit region are not split. | If the route is extended, measures change to retain x,y. |
Cover | No action. | The shape is regenerated to the new location of route measures. | If the route is extended, measures move to retain x,y. |
注：
Since the LRS is time aware, edit activities—such as extending a route—time slices routes and events.
Detailed behavior results
The following sections detail how event behavior rules are enforced when a route is extended.
Stay Put behavior
The route is active from 1/1/2000, and if the extension is set to occur on 1/1/2005, 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 20, and a time slice from 1/1/2005 to <Null>, with measures from 20 to 40, that stay the same geographically.
- 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 20 to 30, and a time slice from 1/1/2005 to <Null>, with measures from 40 to 50, that stay the same geographically.
- Event3 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 to 45, and a time slice from 1/1/2005 to <Null>, with measures from 50 to 65, that stay the same geographically.

Move behavior
The route is active from 1/1/2000, and if the extension is set to occur on 1/1/2005, 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 and a time slice from 1/1/2005 to <Null>, both with the original measures 0 to 20. Since the new time slice can locate both route and measure, events move to preserve measures from 0 to 20.
- Event2 is represented by two time slices. There is a time slice from 1/1/2000 to 1/1/2005 and a time slice from 1/1/2005 to <Null>, both with the measures from 20 to 30. Since the new time slice can locate both route and measure, events move to preserve measures from 20 to 30.
- Event3 is represented by two time slices. There is a time slice from 1/1/2000 to 1/1/2005 and a time slice from 1/1/2005 to <Null>, both with the original measures 30 to 45. This new time slice has measures from 30 to 45 as well.

Detailed behavior on routes in a line network with events that span routes
The following sections detail how event behavior rules are enforced when a route on a line in a line network is extended.
Stay Put behavior
The routes are active from 1/1/2000, and if the extension is set to occur on 1/1/2005, 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 10 on Route1 to 30 on Route3 with the same geographic location.
- 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 Route3 to 48 on Route4 with the same geographic location.

The route is active from 1/1/2000, and if the extension is set to occur on 1/1/2005, 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. Since the new time slice can locate both route and measure, the event moves to preserve measures from 0 to 30.
- Event2 is represented by two time slices. There is a time slice from 1/1/2000 to 1/1/2005 and a time slice from 1/1/2005 to <Null>, both with the measures from 30 on Route3 to 48 on Route4.

Retire behavior
The routes are active from 1/1/2000, and if the extension is set to occur on 1/1/2005, this has the following effects:

There is a time slice from 1/1/2000 to 1/1/2005, with the 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.

Detailed behavior on concurrent routes with Cover behavior
The following sections detail how the Cover event behavior rule is enforced when concurrent routes result after extension.
Concurrent routes with Cover behavior and a nonspanning event
In the following scenario, Route2 on LineA is extended at the beginning with the Cover behavior configured as the event behavior:
The Route2 extension uses two centerlines (CL1 and CL2).
The route is active from 1/1/2000, and if the extension is set to occur on 1/1/2005 with Recalibrate route downstream chosen, this has the following effects:
- Event1 is represented by two time slices after extension. There is a time slice from 1/1/2000 to 1/1/2005 with the original measures from 0 to 15, and a time slice from 1/1/2005 to <Null> with updated measures from 5 to 30.

After extension of concurrent routes with Cover behavior and a nonspanning event
After extension, Route2 is concurrent with the dominant route, Route1 on LineB, at the beginning of the extended section.
Event1 does not cover the section where Route2 overlaps Route1 since Route1 is the dominant route in the concurrent section.

Concurrent routes with Cover behavior and spanning events
In the following scenario, Route2 on LineA is extended at the beginning with the Cover behavior configured as the event behavior.
The Route2 extension uses two centerlines (CL1 and CL2) and there are two events that span routes.
The route is active from 1/1/2000, and if the extension is set to occur on 1/1/2005 with Recalibrate route downstream chosen, this has the following effects:
- Event1 is represented by two time slices after extension. There is a time slice from 1/1/2000 to 1/1/2005 with the original measures from 0 on Route2 to 17, and a time slice from 1/1/2005 to <Null> with updated measures from 5 on Route2 to 17 on Route3.
- Event2 is represented by two time slices after extension. There is a time slice from 1/1/2000 to 1/1/2005 with the original measures from 17 on Route3 to 36 on Route4, and a time slice from 1/1/2005 to <Null> with the same measures from 17 on Route3 to 36 on Route4.
