TomTom today announces the 2012 Congestion Index, a report comparing
congestion levels in 2012 versus 2011 in 161 cities and across five
continents. The Annual Congestion Index finds Moscow the most congested
On average, journey times in Moscow are 66% longer during non-congested
periods when traffic is flowing freely, and 106% longer during morning
rush hour. TomTom’s Congestion Index, including individual continent and
city reports, can be found at www.tomtom.com/congestionindex.
TomTom’s Congestion Index is the world’s most accurate barometer of
congestion in urban areas. The Index is uniquely based on real travel
time data captured by vehicles driving the entire road network. TomTom’s
traffic database contains over six trillion data measurements and is
growing by five billion measurements every day.
The top ten most congested cities, ranked by overall Congestion Level,
in 2012 are:
1. Moscow 66%
2. Istanbul 55%
3. Warsaw 42%
4. Marseille 40%
5. Palermo 39%
6. Los Angeles 33%
7. Sydney 33%
8. Stuttgart 33%
9. Paris 33%
10. Rome 33%
"TomTom’s Annual Congestion Index provides accurate insight into the
world’s most congested cities,” said Ralf-Peter Schäfer, Head of Traffic
at TomTom. “This detailed knowledge of the entire road network helps
businesses and governments to make more informed decisions about how
best to tackle, and avoid congestion. TomTom’s world-class traffic
information also helps drivers get to their destinations faster.
Significantly, when used on a large scale, TomTom HD Traffic has the
potential to ease congestion in cities and urban areas by routing
drivers away from congested areas.”
Notes to Editor
About the TomTom Congestion Index
The methodology used in the Congestion Index compares measured travel
times during non-congested periods (free flow) with travel times in peak
hours. The difference is expressed as a percentage increase in travel
time. The Index takes into account local roads, arterials, as well as
highways. All data is based on actual GPS based measurements.
As well as assigning and ranking the overall congestion levels of over
161 cities around the world, the report analyses the congestion levels
in cities at different times of the day and on different days of the
week. TomTom analysed capital cities as well as cities with a population
of over 800,000. In addition, a selection of key cities with smaller
populations was included based on their regional importance to the
transportation network. The purpose of adding these smaller cities was
to provide a better understanding of congestion levels within individual
Individual city reports include more detailed information such as the
most congested day, time delay per year for commuters and congestion
levels on main and secondary roads.
Separate European, North American, Australia/New Zealand and South
Africa Congestion Index reports are available.
