Event behavior for realigning routes with the cover option

  • Event covering the entire route
  • Event covering the entire route with a time slice
  • Event partially covering the route
  • Event partially covering the route with a time slice
  • Creating concurrent routes during realignment

When routes are realigned, events are impacted depending on the event behavior that is configured for each event layer.

The cover event behavior modifies the geometric location and measure of a line event to make the event go across the newly modified section. The following scenarios describe the results of the Apply Updates tool on event features in the edit activity region for the cover event behavior.

Event covering the entire route

When realigning a route, any event with cover behavior configured will be stretched to cover the newly realigned portion of the route.

In the following example, the initial from and to measures for Route1 and Event1 are 0 and 20, respectively. The route is realigned between measures 6 and 12, and after realignment the from and to measures of Route1 become 0 and 24, respectively.

Upon applying the event behaviors, Event1 will cover the entire route including the newly realigned portion. The from and to measures of Event1 also become 0 and 24.

Note:

The LRS is time aware, so edit activities such as realigning a route will time slice routes and events.

Event covering the entire route with a time slice

In the following example, the route is active from 1/1/2000 and a realignment is set to occur on 1/1/2005.

Event partially covering the route

When realigning a route, any partial event with cover behavior configured will be stretched proportionally in the newly realigned portion of the route.

In the following example, the from and to measures for Route1 are 0 and 20, respectively. The route is realigned between measures 6 and 12, and after realignment the from and to measures of Route1 become 0 and 24, respectively.

The initial from and to measures for Event1 are 0 and 9. Upon applying the event behaviors, Event1 will proportionally cover the route and the from and to measures for Event1 become 0 and 11.

Creating concurrent routes during realignment

In the following example, the from and to measures for Route1 and Event1 are 0 and 20, the from and to measures for Route2 and Event2 are 0 and 6, and the from and to measures for Route3 and Event3 are 0 and 6.

The realignment creates concurrent sections along Route2 and Route3. In this example, Route2 is most dominant followed by Route1 and Route3.

Upon applying the event behaviors, Event1 will cover the Route including the newly realigned portion and excluding the concurrent portion of Route2, and Event3 from the non-dominant section will be retired.

Note:

If RealignOverlap is set to Snap and RealignRoute is set to Cover in your event behavior rules, then cover event behavior will be applied for the realigned route portion and events in the realigned section will be snapped to the concurrent route.
