Trip planning tools

We are building a small set of calculators for the parts of a road trip that are arithmetic rather than opinion: gas bottle fittings across borders, what a route actually costs in tolls and vignettes, and where the next confirmed water and service point is.

None of them are finished, so none of them are listed. This site inherited two calculators built for American RVs and they were deleted rather than dressed up, because a generator sizing tool answers a question almost nobody asks on a European aire.

When a tool exists it will appear here, it will run in your browser, and it will show its working. In the meantime the useful pages are the explanation of where our information comes from and the country rules themselves.
