Hi Derek,
The link here leads to a 404 error page. Could you provide the link to the data model?
Thanks!
Chadwick
Hi Chadwick,
My answer you're referencing to in this thread is 6 years old. I'm not sure if the data model is still applicable. Please review this help topic on UML design for geodatabases in the Desktop help,
A note about the use of UML for geodatabase design—ArcGIS Help | ArcGIS for Desktop
It refers to the Transportation data model here, http://downloads2.esri.com/support/TechArticles/Transportation_Data_Model.pdf - but this is more of a resource document.
Suggest that you also post in this GeoNet discussion place: https://community.esri.com/community/transportation/overview
Hope this helps,
