The TomTom Traffic Index, an annual report that provides data and information on traffic trends in 387 cities in 55 countries throughout 2023 makes for grim reading for Dublin motorists.

The TomTom Traffic Index is based on data from over 600 million in-car navigation systems and smartphones.Dublin is the city where commuters lose the most time in rush-hour traffic jams.

For each city TomTom calculates the average travel time per kilometer from the time it took to cover the millions of kilometers driven across the entire network in the year 2023.

The trend over 2023 confirms the general decline in average speeds in most cities: of the 387 cities analyzed in the traffic index, 82 saw their average speed remain unchanged, and 77 had a higher average speed (and therefore shorter journey times) than the previous year. In the remaining 228 cities, average speeds decreased.

In London and Dublin, the two cities with the lowest average speed, travel times for a 10-kilometer journey increased by +1 minute compared to 2022.

The increase in both the cost of petrol and fuel consumption, due to longer journey times, has a clear impact on the budget of motorists .

In more than 60% of 351 cities where TomTom aggregates fuel prices, the average budget in fuel increased by 15% or more between 2021 and 2023.

This increase in consumption naturally has a direct impact on average CO2 emissions per vehicle.

London’s road infrastructure is not the only reason why travel times are slower than in any other city in the world:

London is also the city in which motorists have lost the most time due to traffic congestion. A 10-kilometer journey in 2023 is 12 minutes and 31 seconds longer on average than the optimum journey time (i.e. with no traffic at all).

Dublin is the city where commuters lose the most time in rush-hour traffic jams.

A motorist spends an average of 1h16 in his or her car to make a typical 10-kilometre journey twice a day during the morning and evening rush hours – but more than 41 minutes of this daily round trip is due to traffic jams. Those who make this journey every day lose 158 hours in traffic jams.

The situation is particularly bad in 2023, with almost 13 hours more than in 2022.
