Today people use tools like Google Maps to plan travel. What if, in somesort of amazing wonder/nightmare world the Romans had technology like Google Maps? The Romans would then use Omnes Viae: Itinerarium Romanum, a Google Map mashup which uses the Tabula Peutingeriana to map out travels on the Roman road network. Using a Latin veneer, Omnes Viae shows not only the route on Google Maps using the Roman road network but also shows the path on the Tabula with all the towns, villages, river crossings, and mountains one would pass through.
I planned a trip from the Eternal City to Jerusalem. Basically one would take a nice excursion through all the major Eastern Empire cities such as Belgrade, Constantinople, Antioch, and Beirut.
