Monday mornings from 8:00-9:00 worst time to be on Germany's roads; Ruhrgebiet ranks third after London and Paris among the most traffic clogged cities in Europe

KIRKLAND, Washington, November 3, 2010 - INRIX(R), the leading provider of traffic information, released the INRIX
Germany 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, German drivers spend more time in traffic compared to drivers
France, but less than U.K., Belgium, Luxembourg and the Netherlands. With
many drivers paying over 1,35 Euro at petrol stations and roads clogged with
traffic congestion on average 34 hours a week across the country's 25 worst
bottlenecks, traffic continues to have a major impact on consumers, the
German economy and the environment.

The scorecard revealed that the worst place and time to be on Germany's
roads is in Stuttgart on Fridays from 16:00- 17:00 where it takes nearly 50
percent longer on average compared to the same journey in uncongested
conditions. Overall, the journey or Travel Time Tax(1) (T3) for Germany was
19,7 percent, meaning that a random journey on roads in urban areas during
peak weekday driving hours takes nearly 20 percent longer on average compared
to the same journey in uncongested conditions. Germany's T(3) is slightly
below the United Kingdom and Benelux (Belgium, Netherlands and Luxembourg)
regions, while more than 25 percent higher than France.

By analyzing traffic on major motorways in the country's 35 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 Cities in Germany(2) span all regions and the worst
hours are:

    1.  Ruhrgebiet: Drivers waste 51 hours per year in traffic(3), Worst Hour
        = Friday, 15:00-16:00
    2.  Hamburg: Drivers waste 44 hours per year in traffic(3), Worst Hour =
        Friday, 15:00-16:00
    3.  Berlin: Drivers waste 35 hours per year in traffic(3), Worst Hour =
        Monday, 8:00-9:00
    4.  Frankfurt am Main: Drivers waste 47 hours per year in traffic(3),
        Worst Hour = Monday, 8:00-9:00
    5.  Koln: Drivers waste 57 hours per year in traffic(3), Worst Hour =
        Monday, 8:00-9:00
    6.  Munchen: Drivers waste 35 hours per year in traffic(3), Worst Hour =
        Monday, 8:00-9:00
    7.  Dusseldorf: Drivers waste 46 hours per year in traffic(3), Worst Hour
        = Monday 8:00-9:00
    8.  Stuttgart: Drivers waste 56 hours per year in traffic(3), Worst Hour
        = Friday 16:00-17:00
    9.  Saarbrucken: Drivers waste 45 hours per year in traffic(3), Worst Hour
        = Monday 7:00-8:00
    10. Bielefeld: Drivers waste 25 hours per year in traffic(3), Worst Hour
       = Wednesday 16:00-17:00

"This is the first detailed and factual report about congestion in
Germany and it allows for a comparison of what traffic is really like and
where it is the worst and when," said Hans Puvogel, GM of 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
Germany's roads helping governments and businesses free people and commerce
from gridlock."

Germany's Traffic Patterns & Worst Bottlenecks

The INRIX Germany 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 35 cities in
Germany, 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 Germany's traffic congestion include:

    - Worst Traffic Day: Thursday
    - Worst Week Day Morning: Thursday
    - Worst Commuting Hour: Monday 8:00-9:00
    - Worst Evening Commute: Thursday
    - Best Week Day for Traffic: Friday
    - Best Week Day Morning: Friday
    - Best Week Day Commuting Hour: Friday 18:00-19:00
    - Best Week Day Afternoon: Monday

In analyzing and ranking the worst traffic bottlenecks across Germany,
the most congested segment is associated with a major roadworks project,
"Project Mittlerer Ring Southwest,"7 in Munich. It is a 0,58 km section of
Heckenstallerstrabe (Mittlerer Ring) heading west up to Hoglworther Strabe,
which was congested 97 hours a week, with an average speed below 23 km/h when

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

    1.  Munich: The Heckenstallerstrabe heading west up to Hoglworther
    2.  Bremen: The A1 towards Bremen near Ahlken
    3.  Hamburg: The A7 towards Hamburg near Hamburg-Bahrenfeld
    4.  Hamburg: The A7 towards Hamburg near Hamburg-Othmarschen
    5.  Koln: The A1 headed towards Euskirchen near Köln-Bocklemund
    6.  Koln: The A59 toward Bonn near Koln-Porz
    7.  Bremen: The A1 toward Bremen near Krummhorens Kuhlen
    8.  Stuttgart: The A8 heading toward Karlsruhe near Hollberg
    9.  Munich: Heckenstallerstrabe heading up to the Passauerstrabe
    10. Ruhrgebiet: The A52 toward Essen at Huttrop

About the INRIX Germany Traffic Scorecard

The INRIX Germany 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 Germany. It leverages
INRIX's Smart Driver Network, the first truly national traffic data
collection network which uses a revolutionary 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 country's largest traffic network, INRIX generates the most
comprehensive and timely congestion analyses to date, covering the 35 largest
metropolitan areas and all of Germany'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 35 Most Congested Cities in Germany, along
with an executive summary of the report findings are now available at the
INRIX Germany Traffic Scorecard website at The

(1) Travel Time Tax (T3): 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,
Hamburg and Damstadt have comparable T3 (20,3% vs. 20,0%) - this implies that
an average commuter in both cities faces similar delays. However, Hamburg has
more than 7 times more people and 10 times the amount of major highways. So
at a system level Hamburg 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
