Right now, it is of no use. But, for those who do have streets which go by multiple names, it is nice to have the data be totally correct.
I use it because often, highways or routes overlap. The primary name is used for the name most used, and alt name is where other names or routes are input. In my state of the US, all highways are named, and those usually have a route #, but not always.
Also, the primary name is used for shield creation, but alternate names can hold a local name if the route name is the most popular local name.
