Virtual Variable Message Signs

Read a document about the concept of a Virtual VMS. In this scenario the road authority send the information of a VMS, giving travel times on two routes, to a service provider in order to incorporate this information in a navigation system.

This remided me of a presentation I saw a couple of month ago. The speaker explained that in the early days of cars, the designers just took a horse wagon, and put a motor on it. The Virtual VMS concept is exactly this way of thinking.
