The Best and Worst European Cities to Drive in as a Tourist is created by Compare the Market, and helps provide an insight into the cities that would be the best for a visitor to drive in.
Within the research, we took a list of cities based on the amount of tourist visitors (Euromonitor tourism study), the congestion levels within each city (INRIX 2018 Global Traffic Scorecard data), the price of secure parking near the top rated attraction (parking sites and TripAdvisor), the cost of fuel in each country (GlobalPetrolPrices.com), road-related fatality rates (Organisation for Economic Co-operation and Development), the road quality ratings from the World Economic Forum, and the car to person ratio in each country (United Nations).
The index created is weighted, as the congestion and parking prices are city-specific, they carry more weight in the final score. The following percentages reflect the weight each column has in calculating a final ranking: 20% - 2 Hours Parking, 20% - Cost of Fuel, 15% - Road Safety, 15% - Road Quality, 15% - Car Density, 15% - Congestion.
