About Diodiometro
Diodiometro is a tool for estimating toll and fuel costs across Greece.
How it works
We map mainline plazas and slip-road ramps along your route using OpenStreetMap data and official motorway tariffs.
Official fares
All toll rates are taken directly from the published tariff tables of each motorway concessionaire across all four vehicle categories and updated regularly. Every fare in our price list links directly to the operator's official page.
Fuel & travel time
Fuel costs are calculated using typical consumption rates per powertrain and current pump prices, both fully customizable. Estimated travel times reflect standard driving conditions.
Ferry alternatives
Where a ferry crossing provides an alternative to a toll road (such as the Rio–Antirrio line), Diodiometro presents a cost and time comparison so you can choose the option that best suits your trip.
Privacy
No account or registration required. Your location queries are anonymized through our server, and your vehicle preferences stay on your device. See our privacy policy.
Feedback & corrections
If you notice a tariff change or timetable update, let us know via our contact form or by emailing diodiometro@info.gr.
Prices and times are estimates and can be wrong. For the driving itself, trust a proper navigation provider.
