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
Köln sits in the heart of North Rhine-Westphalia, the region with the largest concentration of the people who actually drive this corridor — Berlin catches the generic search, this route catches the drivers. It crosses the same countries as the Munich route but reaches the Alps another way: out of Croatia at Macelj, a short run past Maribor in Slovenia, Austria by Graz and the A9 Pyhrn motorway, then more than seven hundred kilometres into Germany. Germany charges a car nothing for its motorways, so the longest country on the trip contributes zero to the crossings line — while the tank there is among the more expensive in Europe. Routes like this are where a country-by-country breakdown earns its keep.
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.
