HOW FAST IS MY
CITY MOVING?
Detailed speed information for any
road segment with high granularity &
advanced features.

WHAT IS CAUSING
CONGESTION?
Incidents, jams, roadworks and road
closures. Reported by the
community or automatically
detected.

Jam Ahead Warnings
Inform road users of dangerous slow downs
Weather related delays
Where should I redirect traffic when a big hail storm is on
its way?
Jam prediction
Make informed decisions based on
how congestion is evolving.
Relative & absolute speed
Compare current speed to freeflow conditions, legal
speed limit or speed profiles.
Turn-dependent jams
Proactively manage traffic lights at cross roads
with detailed lane level traffic.
HOV & express lanes
Different lanes, different rules, different traffic.
You know the difference, so do we.

ANALYZE MEASURE IT. IMPROVE IT.

WE’VE BEEN AT IT
FOR 10 YEARS
We started capturing and storing
traffic data back in 2007. 19 trillion
data points, 400 terabytes, 10 years
of historical data, just a few clicks
away.

IT’S ALL IN THE DATA
Network performance. Traffic
models. Impact assessments.
Transportation planning. It can only
be as good as the data it crunches.

WHERE ARE THE
BOTTLENECKS?
With detailed speed data & travel
times, it’s easy to measure the
performance of any route or area
over time and pinpoint problems.

WHICH ARE THE
MOST USED ROADS?
With years of probe counts available,
understand how road usage evolves over
time and determine which roads require
the most attention.

NO MORE EXCUSES.NO MORE APPROXIMATIONS.

ANALYZE: SPEED PROFILES
Speed Profiles gives access to a uniquely large database
of historical travel time data to the governmental and
business markets for various uses.
Speed Profiles provides an average measured speed for
each road segment based on two years of historical travel
time data:
• Data available for each map segment for each
direction
• Coverage on all the roads
• High granularity of data: every 5 minutes and every
day of the week
Speed profiles used in routing provide
accurate ETAs
Average speeds for every day of the week
every 5 minutes

ANALYZE: CUSTOM AREA ANALYSIS
Custom Area Analysis offers governmental and business
markets an extremely detailed set of information across a
wide road network for various use cases – including
bottleneck analysis, performance measurement, traffic
modelling support and site location studies.
• This product can be accessed via the Traffic Stats
Portal
• The input of a query is composed of an Area, a Date
Range, and Time Slices
• The output contains data about:
• Speeds: median, average, percentiles
• Standard deviation
• Travel times
• Sample size
• Travel Time Ratio
• In SHAPE format
A Custom Area Analysis is used to analyse
the performance of a highway interchange

ANALYZE: CUSTOM PROBE COUNTS
TomTom Custom Probe Counts allows users to query the
TomTom historical traffic database to get a rough overview
on the relative density of cars and the distribution between
locations and times. Where the Probe Count is a proxy to
the total number of vehicles on a road, the absolute value
of probe counts is only the sample of people using
navigation and uploading it in our data sharing program.
Portal
• The input of a query is composed of an Area, a Date
• Sample size
• In SHAPE format
Custom Probe Counts can be used to
compare the usage of a road against another

ANALYZE: CUSTOM TRAVEL TIMES
Custom Travel Times gives access to a uniquely large
database of historical travel information to the
governmental and business markets to analyse specific
roads or routes in fine detail.
Portal or our API
• The input of a query is composed of a Route, Date
• Speeds: median, average, percentiles

MAKE DRIVERS
PART OF THE SOLUTION

WORKING TOGETHER
Research shows that 10% of drivers
using traffic information leads to a
5% reduction in travel time for all.
Drivers can be part of the solution.

HOW TO COMMUNICATE WITH
DRIVERS?

With this tool, Cities can publish data from multiple departments, including road closures, construction
and special events so drivers can find alternative routes, helping ease congestion within city limits.
✓ Influence the traffic using
the TomTom Traffic Engine
✓ Inform road users of
accidents to help them
route around them
✓ Plan events in advance
such as marathons or
roadworks
✓ Plan recurrent events such
as markets
