Pricing:
The Pricing category comprises four factors:
Tolls policy
The countries have been divided into four groups based on their method of toll charging:
1 – toll-free motorways
2 – tolls only for certain bridges/tunnels
3 – toll collection at toll gates (fixed price or distance-based)
4 – motorway charged by vignette (time-based)
These four groups have been weighted with 1 ranked the best and 4 the worst. Due to the difficulty in comparing distance vs. time-based payment methods, the simplification has been made here that vignette as the unavoidable cost should be rated the lowest.
