Realignment Event Behaviour

ColinSchut — Wed, 18 Sep 2019 22:15:23 GMT

Hi all,

Currently testing different route changes and the implications for event behaviour and have a question regarding realignments.

Let's say I have an event that goes from 0 measure to 100, and dates before and after the realignment which is measure 40 to 60. I need the start and end locations to stay in the existing geographic locations.

Completing the realignment will retire that event (and downchain ones) and create two new events from 0 to 40 and 60 to 100 with no record covering 40 to 60 on the new alignment. This seems to be the case whatever behaviour I try.

I could change new event 1 to cover the distance and delete new event 2, but this seems clunky to do for every event feature. Am I missing something in the combination of event behaviour rules to have it do what I need?

Thanks

Hi Colin,

The scenario you're describing would be an event behavior we added to Roads and Highways at 10.6 called Cover. See this page for more information: http://desktop.arcgis.com/en/arcmap/latest/extensions/roads-and-highways/scenarios-of-the-cover-event-behavior-for-realigning-a-route.htm

Thank you very much, in particular for that help page. I actually thought I had tested cover but must have made an error somewhere.

I found the description on this page a bit confusing because of it stating it changes measures and geographic location, but I can see what it means now.

Thanks again.

Colin,

Instead of changing event 1 and retiring event 2. Why not add event 3 to the new alignment, using beginning and end toggle button. That should retire event 1 and 2. A manual option to cover behavior.
