Paris tops all European Cities for Worst Traffic; Tuesday mornings from 8:00-9:00 worst time to be on French roads; Eight of Europe's Top 10 Traffic Bottlenecks in France

KIRKLAND, Washington, November 3, 2010 - INRIX(R), the leading provider of traffic information, released the INRIX
France Traffic Scorecard, a comprehensive country-wide perspective and
city-by-city analysis on traffic congestion. A comparison among six different
countries found that Paris is the most congested city on the continent,
followed by London. Germany's biggest metropolitan area Ruhrgebiet comes in


Generally, Ile de France drivers spend more time in traffic compared to
drivers in the UK, Germany, Belgium, Luxembourg and the Netherlands. With
many drivers paying over euro 1,44 at petrol stations and roads clogged with
traffic congestion on average 70 hours a week across the country's 25 worst
bottlenecks, traffic continues to have a major impact on consumers, the
French economy and the environment.

The scorecard revealed that the worst place and time to be on French
roads is in Ile de France on Tuesday from 8:00-9:00 where it takes nearly 52
percent longer on average compared to the same journey in uncongested
conditions. Overall, the journey or Travel Time Tax(1) (T3) for France was
14,3 percent, meaning that a random journey along urban area roads during
peak weekday driving hours takes 14 percent longer on average compared to the
same journey would take in uncongested conditions. The T3 for France is the
best among the countries analysed, well below the United Kingdom, Germany and
the Benelux region.

By analysing traffic on major motorways in the country's 27 largest
metropolitan areas, the Scorecard provides a comprehensive snapshot into the
intractable issues of urban traffic congestion. According to the report, the
Top 10 Most Congested metropolitan areas in France(2) and the worst hours

    1. Paris/IdF: Drivers waste 70 hours per year in traffic(3), Worst Hour =
       Tuesday 8:00-9:00
    2. Lyon: Drivers waste 34 hours per year in traffic(3), Worst Hour =
       Tuesday 8:00-9:00

    10. Poitiers: Drivers waste 25 hours per year in traffic(3), Worst Hour =
        Monday 17:00-18:00

"While traffic outside of the Paris region isn't nearly as bad as in
other European countries, the fact that eight of Europe's Top 10 worst
bottlenecks are located in Ile de France shows that traffic has a significant
impact on the French economy, the environment as well as the mobility of its
citizens," said Hans Puvogel, General Manager, INRIX Europe. "Our business is
built on knowing what's going on with traffic day in and day out in 20
countries. The Scorecard, and the data powering the report, will contribute
enormously to a better understanding of traffic congestion on French roads
helping governments and businesses free people and commerce from gridlock."

France's Traffic Patterns & Worst Bottlenecks

The INRIX France Scorecard takes a micro look at traffic problems all
across the country - zooming in on the total hours spent in traffic, worst
day of the week for commuting and average speeds for the top 27 cities in
France, along with hundreds of other details including the identification of
the worst traffic bottlenecks the country's drivers crawl through every day.
Unique patterns evolving out of France's traffic congestion include:

    - Worst Traffic Day: Thursday
    - Worst Week Day Morning: Tuesday
    - Worst Commuting Hour: Tuesday 8:00-9:00
    - Worst Afternoon Commute: Friday
    - Best Week Day for Traffic: Monday
    - Best Week Day Morning: Friday
    - Best Week Day Commuting Hour: Monday 6:00-7:00
    - Best Week Day Afternoon: Monday

In analysing and ranking the worst traffic bottlenecks across France, the
most congested segment (in all countries analysed in fact) is a 0,41 km
section of the Boulevard Peripherique Exterieur at Porte d'Ivry (Junction 2)
in Paris, which was congested on average 99 hours a week, with an average
speed below 23 km/h when congested.

According to the report, the Top 10 Worst Traffic Bottlenecks in France

    1. Paris Boulevard Peripherique direction Porte d'Orleans at Porte d'Ivry
    2. Paris Boulevard Peripherique direction Porte d'Orleans at Porte
    3. Paris A 86 direction Champigny Sur Marne at Exit Rancy

About the INRIX France Traffic Scorecard

The INRIX France Traffic Scorecard uniquely measures the country's
traffic congestion problem by going beyond the traditional limitations of
road sensors and statistical sampling techniques to evaluate real-time
traffic on almost every major metropolitan roadway in France. It leverages
INRIX's Smart Driver Network, the first truly national traffic data
collection network based on a crowd-sourced approach to collecting traffic

Each data report from these GPS-equipped vehicles and devices includes
the speed, location and heading of a particular vehicle at a reported date
and time with commercial vehicles reporting every minute for up to 7 hours
per day. With the world's largest traffic network, INRIX generates the most
comprehensive and timely congestion analyses to date, covering the 27 largest
metropolitan areas and all of France's major highways, interstates and
limited access roads. INRIX then processes and blends other relevant
traffic-related data such as road sensors, traffic accident and incident data
and other resources to provide the most comprehensive and accurate traffic
information available.

Rankings and scorecards of the Most Congested Cities in France, along
with an executive summary of the report findings are now available at the
INRIX France Traffic Scorecard website at The
extensive data powering the INRIX France Traffic Scorecard is immediately
available under license for further analysis and review by government
agencies and commercial organizations including transportation industry

To learn more about the Scorecard's findings, you can also register for a
free webinar planned for November 10, 2010 at 11:00 a.m. GMT/6 a.m. ET where
INRIX Vice President of Public Sector Rick Schuman and GM of INRIX Europe
Hans Puvogel will provide a detailed review of key findings and INRIX traffic
data can be applied to improving transportation planning, traffic management
and measuring system performance.

technology revolution behind the next generation of navigation and
location-based service applications, go to

(1) Travel Time Tax (T3): The methodology used to measure overall
congestion and to establish Urban Area T3 for each of the weekly 40 peak
period drive time hours enables the calculation of total France Urban Area
congestion metrics, by hour, by morning and evening drive time, by day and

T3 expresses the average amount of extra time it takes to travel relative
to free-flow travel. A T3 of 30%, for example, indicates a 20-minute
free-flow journey will take 26 minutes during the peak travel time periods, a
6-minute (30%) journey time penalty. For each road segment, a T3 is
calculated for each hour of the week, using the formula T3= Reference Speed
(RS) minus Hourly Average Speed (HS)/RS. Note if HS > RS, T3 is set to 0%. T3
is a direct derivative of Travel Time Index, a common metric used in
congestion analyses.

(2) Overall Congestion vs. Travel Time Tax (T3): Overall congestion
quantifies and ranks the total congestion in a region. Larger regions tend to
have more roads and more locations where congestion occurs, hence more
overall congestion. Travel Time Tax (T3) equalizes all regions by dividing
out the difference in the size of each region's road network - giving a more
driver centric view of congestion. For example, London and Birmingham have
comparable T3 (25.0% vs. 24.3%) - this implies that an average commuter in
both cities faces similar delays. However, London has roughly 5 times more
people and more than 3 times more road miles of major highways. So at a
system level London has much more overall congestion while individuals in
both regions each face similar congestion levels.

An analogy is power consumption - the amount of power consumed in each
home is similar to the T3; while the amount of total power consumed in a
region is similar to overall congestion. Both measures - power used in each
home (T3) and power used overall in the region (overall congestion) - are
relevant and thus measured.

(3) Based on a one-way uncongested commute of 30 minutes during peak
travel hours
