Lines naming a toll plaza are the published price of a plaza the route actually drives through. Lines reading "tolled road" have their distance measured from the route but charge a national average rate; lines reading "motorway (assumed)" assume the distance too, because plaza-level data does not exist yet for that country. Bridge, tunnel, vignette and published transit prices are actual prices.
What we do not know
Every toll on this route comes from a published tariff. No line rests on an assumption.

About this route
The only route that heads east rather than west, and it changes the shape of the sum entirely. Georgia charges nothing anywhere on its network — not "free apart from a few structures" the way Germany is, but genuinely nothing; the East-West Highway that carries every route from Sarp to Tbilisi is state-built and free. The measurement shows it plainly: on a sixteen-hundred-kilometre drive the entire crossing cost arises on the Turkish side, and the Georgian line is fuel alone. This is the cleanest demonstration on the site that what you pay in tolls is a fact about the country, not about the distance.
What this figure leaves out
Accommodation, food, waiting at borders, tyres and wear, green card insurance, parking. Only fuel and the charges on the road itself are counted.
