TomTom (TOM2), the geolocation technology specialist, today
releases the 13th edition of its TomTom Traffic Index, an annual
report that provides data and information on traffic trends in 387
cities in 55 countries throughout 2023.
The TomTom Traffic Index is based on data from
over 600 million in-car navigation systems and smartphones. For
each city (both the city center and the wider metropolitan area),
TomTom calculates the average travel time per mile from the time it
took to cover the millions of miles 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 6-mile journey increased by
almost 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 who have to use their car every day to get to
work. 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 had a direct impact on
average CO2 emissions per vehicle.
A global challenge: Traffic congestion
continues in cities worldwide
“With more than half of the world's population
living in urban areas, traffic congestion and its economic,
ecological and health consequences have become a problem that needs
to be urgently addressed”, said Ralf-Peter Schäfer, Vice President
of Traffic at TomTom. “Planning the future of urban areas is
essential to ongoing traffic management. Large urban areas are
harnessing Big Data to plan infrastructure and development that
will alleviate traffic congestion. Analysis of historical traffic
data can help growing cities map more efficient road systems and
plan better zoning using location intelligence. Effective
implementation of planning measures such as the implementation of
LEZs to reduce air pollution will benefit from data from connected
cars.”
The TomTom Traffic Index has become over time a
comprehensive tool for urban planners, policymakers, and drivers,
as it helps to understand and manage traffic congestion, and
provides insights into the impact of congestion on a city's
transportation infrastructure and economy. Real-time traffic data
can feed the algorithms used by municipalities to manage traffic
jams by optimizing road logistics and routes. According to a
McKinsey study, this can reduce commuting times in cities by
15-20%. Data can be used to prevent traffic jams through
intelligent traffic light synchronization, variable speed limits
and real-time alerts showing drivers the fastest routes.
TomTom Traffic Index – 2023
Rankings
ALL-YEAR AVERAGES THROUGH 2023
(24/7)
Average travel times: in which city do people drive the
slowest?
Travel time is the result of multiple factors,
which can be grouped into static factors such as road network
configuration, road sizes and capacities, or speed limits - plus
dynamic factors like traffic congestion, roadworks, bad weather,
etc., providing changes in traffic flow.
The TomTom Traffic Index shows travel times in
different cities and ranks them the slowest speed in each city.

For the second year in a row, London was the
slowest city to drive in 2023. The capital of England has the
lowest base speed due to the static factors, such as the absence of
any fast road, and speed limits changed to 20mph on most roads over
the past years - so, even in optimal traffic conditions, the
average speed in London is slower than any other city in the
world.

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 6-mile journey in 2023 is 12
minutes and 5 seconds longer on average than the optimum journey
time (i.e. with no traffic at all).
At the level of wide metropoles, Manila is the
one in which motorists see their journey times lengthened the most
compared to the optimal travel time (+9 min. 3 sec. in average, for
a 6-mile trip).

Dublin is the city where commuters lose the most
time in rush-hour traffic jams. A motorist spends an average of
1h14 in his or her car to make a typical 6-mile journey twice a day
during the morning and evening rush hours - but more than 40
minutes of this daily round trip is due to traffic jams. Those who
make this journey every day lose 153 hours in traffic jams. The
situation got particularly worse in 2023, with 12 hours and 31
minutes more than in 2022.

In Hong Kong, where the petrol price is
particularly high, a 6-mile round trip driven every day with a
typical petrol-powered car cost a commuter US$ 1,033 in 2023; but
in Paris, traffic has had a very significant impact on a daily
commuter's budget, with traffic jams "costing" them almost US$ 300
in 2023, i.e. a 45% increase in the fuel budget if these trips had
been made under optimal conditions.

Notes to Editors
About the TomTom Traffic
IndexUrban mobility is a key contributor to issues such as
climate change, health and economic development and the TomTom
Traffic Index has become the barometer of mobility patterns around
the world. TomTom’s traffic data, which is powered by 600 million
connected devices, is an authoritative indicator of how people
move, economic activity levels, global trade and much more. For
years, TomTom’s Traffic Index has been used by analysts,
corporations and the media to explain a world in flux.
Which data does TomTom use for the
Traffic Index?We source our traffic flow data from over
600 million devices, such as in-dash car navigation, smartphones,
personal navigation devices and telematics systems. Each day,
TomTom collects from these sources over 61 billion anonymous GPS
data points around the world, covering a total distance of more
than 3 billion miles driven. This real-time data is archived and
accessible as historical data right away. 58 billion driving hours
have been accumulated in TomTom’s historical traffic data.
2023 TomTom Traffic Index
methodology
- Travel times and Time
lost
For each city (both the city center and the
wider metropolitan area), TomTom calculates the average travel time
per mile from the time it took to cover the millions of miles
driven across the entire network in the year 2023. This makes it
possible to estimate the average time taken to cover a typical
6-mile journey in 2023, so that cities can be compared with each
other, and year-on-year trends can be assessed. The TomTom Traffic
Index determines the optimum travel time (no traffic) and indicates
how much these travel times increase on average at different times
of day and on different days of the week due to traffic
conditions.
TomTom defines the cost of driving as the amount
of time, fuel and CO2 used per km or per mile. The cost of driving
is the difference between the figures in optimal traffic conditions
and the actual average figures, considering the extra amount of
average time spent on the road. TomTom collects real-time fuel
prices for thousands of stations around the world. To assess fuel
costs, TomTom data is based on country-averaged daily pricing over
2022.
Emission from traffic is directly proportional
to a vehicle’s energy consumption. To raise those consumption
models, TomTom used the PHEM (Passenger car and Heavy-duty Emission
Model) simulation tool developed by the Graz University of
Technology (TU Graz). PHEM calculates the energy required to
perform any observed driving maneuvers (speeds, accelerations) from
TomTom data for different road profiles, and estimates the
resulting emissions, based on the vehicle efficiency, vehicle and
energy type (petrol, diesel or electric), as well as speeds.
The TomTom Traffic Index report is
available onlineAt tomtom.com/Traffic-Index, anyone can
discover where their city ranked in 2022, how travel times changed
year on year, and how much their driving habits cost.
