I'm viewing Transportation Analytics Q&A, and the presenter was saying that I can find sample apps in the resource center... but there's nothing in the resource center about Transportation Analytics, no Apps no links nothing... any help?
As you found out, ArcGIS for Transportation Analytics does not have a devoted Resource Center page. For information about what the Transportation Analytics bundle is, the product page is best. That is available here: http://www.esri.com/software/arcgis/arcgis-for-transportation-analytics
The two sample applications you are referring to are the RoutePlanner and Status Dashboard. The RoutePlanner app is available on both GitHub and on ArcGIS.com. The Status Dashboard is available on GitHub. Those links are below.
