Retire routes—ArcGIS Pro

Mit der Location Referencing-Lizenz verfügbar.

During the life span of a roadway, the routes may change as portions of the route are removed while others are added. Major changes, such as environmental concerns, age, erosion, or repair work, may require a portion of a route or the entire route to be retired for a specific period of time.

When you specify that a portion of a route should be retired, that portion is removed from the route in the LRS Network for the specified time frame. When a route is retired using the Retire Route tool, the route's To Date field in the LRS Network feature class is populated with the retirement date.

When portions of a route are retired, the centerline features are split to accommodate the precise location of the retire operation. Calibration points are also added to ensure that the remainder of the route continues to calibrate properly.

Route retirement scenarios

The following are examples of route retirement scenarios:

Retirement on a route without recalibration

Retirement is from the start of the route to the middle portion of the route.


From Route	RouteX
From Measure	0
To Measure	5
Recalibrate Downstream	No

After retirement, the route is not recalibrated, leaving the downstream measures intact. The start measure of the remaining route is updated to the same value as the start measure of the route before its retirement.

Retirement on a route with downstream recalibration

Retirement is from the start of the route to the middle portion of the route. The route is recalibrated downstream and the downstream measures are updated.


From Route	RouteX
From Measure	0
To Measure	5
Recalibrate Downstream	No

Complex route retirement scenarios

The following are examples of route retirement scenarios on complex routes including loop, lollipop, branch, alpha, and infinity routes.

Retirement on a loop route

In the following example, a route (RouteX) has a start measure of 0 and an end measure of 12. Retirement takes place from the middle to the end of a loop route.


From Route	Route X
From Measure	9
To Measure	12
Recalibrate Downstream	Yes

After retirement, RouteX becomes a simple route.

Retirement on a loop route

In the following example, a route (RouteX) has a start measure of 0 and an end measure of 15. Retirement takes place in the middle of the lollipop route.


From Route	Route X
From Measure	4
To Measure	8
Recalibrate Downstream	Yes

After retirement, RouteX becomes a branch route.

In the second example, retirement takes place from the middle to the end of the lollipop route.


From Route	Route X
From Measure	12
To Measure	15
Recalibrate Downstream	Yes

After retirement, RouteX becomes a loop route.

Retirement on a branch route

In the following example, a route (RouteX) has a start measure of 0 and an end measure of 9. Retirement takes place from the beginning to the middle of the branch route.

Input on a branch route with retirement at the start


From Route	Route X
From Measure	0
To Measure	3
Recalibrate Downstream	Yes

After retirement, RouteX becomes a simple route.

Output on a branch route with retirement at the start

In the second example, retirement takes place from the middle to the end of the branch route.

Input on a branch route with retirement in the middle


From Route	Route X
From Measure	6
To Measure	9
Recalibrate Downstream	Yes

After retirement, RouteX becomes a simple route.

Output on a branch route with retirement in the middle

Retirement on an alpha route

In the following example, a route (RouteX) has a start measure of 0 and an end measure of 18. Retirement takes place from the start to the middle portion of the alpha route.


From Route	Route X
From Measure	0
To Measure	6
Recalibrate Downstream	Yes

After retirement, RouteX becomes a simple route.

Retirement on an infinity route

In the following example, a route (RouteX) has a start measure of 0 and an end measure of 24. Retirement takes place from the middle to the end of the infinity route.


From Route	Route X
From Measure	18
To Measure	24
Recalibrate Downstream	Yes

After retirement, RouteX becomes an alpha route.

Retire route parameters

The following table lists the parameters used in the Retire Route tool:


Parameter	Description
Network	The network in which the routes exist.
Retire Date	The date when the retirement takes place.
Route ID	The route on which the retirement takes place.
From Measure	The measure on the route where the retirement starts. This is displayed as a green dot.
Use route start measure	The starting measure of the route.
To Measure	The measure on the target route where the retirement ends. This is displayed as a red dot.
Use route end measure	The ending measure of the target route.
Recalibrate route downstream	Choose this option to remove the length of the retired route from your overall set of measures.

Complete these steps to retire a route:

Hinweis:

Gap calibration rules are followed when editing routes.

Add the centerline and network feature class to a map.
You can also open a map in which the centerline and network feature class is already present.
Hinweis:
The information model expects only one centerline at any given location. Ensure that the centerlines you're using for your edit do not overlap other centerlines in your LRS.
Hinweis:
Traditionally versioned networks must be edited through a direct connection to the geodatabase. Branch versioned networks, including any network configured with a user-generated route ID, must be edited through a feature service.
Zoom in to the location where you want to retire the route.
Click the Retire button on the Location Referencing tab.
The Retire Route pane appears.
Choose the Network in which the retirement will take place.
Hinweis:
To edit using feature services, the LRS Network must be published with the linear referencing and version management capabilities.
Click the Calendar button next to the Retire Date text box and choose a retirement date.
Tipp:
You can also double-click the Retire Date text box to automatically populate it with today's date or type a date in the Retire Date text box.
Click the Choose route from map button next to the Route ID parameter and select a route to retire on the map.
Provide the start measure value in the From Measure text box or click the Choose measure from map button to select the start measure on the map.
A green dot appears at the location of the start measure on the route.
Tipp:
You can also check the Use route start measure check box to choose the start measure of the route.
Provide the end measure value in the To Measure text box or click the Choose measure from map button to select the end measure on the map.
A red dot appears at the location of the end measure on the route.
Tipp:
You can also check the Use route end measure check box to choose the end measure of the route.
Hinweis:
Check the Recalibrate route downstream check box if you want to remove the length of the retired route from your overall set of measures.
If the Recalibrate route downstream check box is not checked, the modified route gets its start measure from the end measure of the retired portion, and the end measure of the modified route remains unchanged.
You can't retire the route if the From Measure and To Measure values for the route are the same.
Click Run.
The selected portion of the route is retired.
Hinweis:
As a result of the retire route activity, only routes or portions of a route are retired; centerlines are not retired.
Hinweis:
If a message about acquiring locks or reconciling appears, conflict prevention is enabled.
