Retire routes

Available with Location Referencing license.

During the life span of a roadway, major changes such as environmental concerns, age, erosion, or repair work, can require a retirement of a route segment, or an entire route to be retired for a specific period of time.

When you specify that a section of a route should be retired, that section 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 sections 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 is calibrated properly.

Route retirement scenarios

Route retirement scenarios are described below.

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

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.

Complex route retirement scenarios

Route retirement scenarios for complex routes including loop, lollipop, branch, alpha, and infinity routes are described below.

Retirement on a loop route

In the following example, 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

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

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, 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:

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

After retirement, RouteX becomes a simple route.

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

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

After retirement, RouteX becomes a simple route.

Retirement on an alpha route

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

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

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

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

After retirement, RouteX becomes an alpha route.

Retire routes in a line network

The following examples demonstrate how routes in a line network can be retired. Line orders are updated if needed.

The first example shows the before and after retirement at the beginning.

Example 1 input

Route ID	Line Order
RouteX	100
RouteA	200
RouteY	300

The first part of RouteX at the beginning will be retired.

After retirement of the first part of RouteX, line order is updated. RouteA now has line order 100, while RouteX is now 200.

Example 1 output

Route ID	Line Order
RouteA	100
RouteX	200
RouteY	300

The second example shows before and after retirement at the end.

Example 2 input

Route ID	Line Order
Route X	100
Route Y	200

The second part of RouteY will be retired.

Example 2 output

Route ID	Line Order
Route X	100
Route Y	200

Line order is unaffected when retiring a route or part of a route at the end.

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:

Note:

Gap calibration rules are followed when editing routes.

1. Add the centerline and network feature class to a map.

   Alternatively, open a map in which the centerline and network feature class are present.

   Note:

   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 the LRS.

   Note:

   Traditionally versioned networks must be edited through a direct connection to the geodatabase. Branch versioned networks, including networks configured with a user-generated route ID, must be edited through a feature service.

2. Zoom in to the location where you want to retire the route.
3. Click the Retire button on the Location Referencing tab.

   The Retire Route pane appears.

4. Choose the Network in which you want to retire a route.

   Note:

   To edit using feature services, the LRS Network must be published with linear referencing and version management capabilities.

5. Click the Calendar button next to the Retire Date text box and choose or type a retirement date.

   Tip:

   You can also double-click the Retire Date text box to automatically populate it with today's date.

6. Click the Choose route from map button next to the Route ID parameter and select a route on the map to retire.

   Note:

   After clicking the Choose route from map button or the Choose measure from map button , you can hover over the route to see the route and measure at the location of the pointer.

   If only one applicable route exists at the edit location on the map, click to select it. If multiple routes are applicable, click the location and choose one of the applicable routes from the Select Route dialog box.

   You can set map scale options for the display of route and measure information on the Options dialog box, on the Location Referencing tab.

7. Provide the start measure value in the From Measure text box or click the Choose measure from map button to populate the start measure.

   A green dot appears at the location of the start measure on the route.

   Tip:

   You can also check the Use route start measure check box to choose the start measure of the route.

8. Provide the end measure value in the To Measure text box or click the Choose measure from map button to populate the end measure.

   A red dot appears at the location of the end measure on the route.

   Tip:

   You can also check the Use route end measure check box to choose the end measure of the route.

   Note:

   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 unchecked, the modified route gets its start measure from the end measure of the retired section, 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.

9. Click Run.

   Note:

   If your route edit will result in the introduction of one or more physical gaps on the route, a prompt appears to alert you before the tool is run. If you don't plan to create a gapped route, answer No and edit the digitized centerlines so that no gaps result during route editing.

   If the route being edited already had one or more physical gaps, and no additional physical gaps were introduced by the edit, no prompt will appear.

   You can prevent unplanned centerlines by enabling snapping in the active map, or by enabling snapping using the Edit tab, Snapping group, Snapping button .

   You can disable this warning by unchecking Warn before allowing route edits that can create physical gaps in Location Referencing options.

   The selected section of the route is retired.

   Note:

   As a result of the retire route activity, only routes or sections of a route are retired; centerlines are not retired.

   Note:

   If a message regarding acquiring locks or reconciling appears, conflict prevention is enabled.
