Goals of Congestion Index:

• The traffic speed data used to create the index is embedded in our navigation devices and applications, including our free web route planner

• By using good navigation and trip planning tools, drivers can save themselves time, cost, fuel and frustration

• Road authorities can use available information to make informed decisions, benefitting all road users and taxpayers

In-vehicle technology and benefits

• Urban, Suburban, Rural• Congested, Uncongested

• Driving distance and travel time savings• Calmer and safer driving• Fuel savings

• Trip planning, route choice• Departure time• Driving style• Mode choice

• Pre-trip planning with (dynamic) traffic information• Navigation with dynamic rerouting• Eco-routing• Real-time driver feedback on fuel use

• Travel time savings• Fuel savings• Safety / accident rate reductions• Transport system efficiency8

In-vehicle technology and benefits: Proof

Fuel Consumption Savings (passenger vehicles): up to 15% with navigation and dynamic rerouting based on real-time traffic information (Naviconnect, 2009)

Travel Time Savings: up to 12% with navigation and dynamic rerouting based on real-time traffic information (German Air and Space Institute, 2012)

Safety: 5-10% fewer accidents when driving with navigation (TNO and others, 2008)

Carbon Footprint Reduction (commercial fleets): up to 25% with real-time driver feedback on fuel use and dynamic routing (Zenith Hygiene, 2012)

Cooperative Traffic Management1. Generate regional traffic data with full coverage via 5-10% of

vehicles

2. Fuse and process data with information from road authorities

3. Share this data with as many drivers as possible in their cars

4. Use the same data for Traffic Management purposes

Collective effect: If 5%-10% of drivers use TomTom HD Traffic or other high-quality, dynamic navigation, the road network will be used more efficiently and travel times will be reduced for everyone.

We believe that peak period travel times can then be reduced by 5% overall.

The pieces of the puzzle are already present

This is happening now:

• Automotive

• Government

• R&D for new services

Renault Carminat TomTom LIVE• First launched in 2009,

LIVE version with HD Traffic in 2011

• High take rates: 48% across range

• Over 1 million devices installed in two years

• Electric Vehicle Systems:

• Routing to and via charge stations

• Battery management solution

• Eco-routing function• LIVE services

HD Flow

VMZ Berlin Berlin Traffic Control Centre

GermanyGovernment

Traffic Management

Requirements:

Regional government in Berlin contracted VMZ (wholly owned subsidiary of Siemens) to run the traffic control centre to monitor traffic conditions and manage the traffic flow throughout the region – on major roads and secondary roads.

Solution:

Chose TomTom HD Flow to provide speed information on all strategic roads in the region every minute. OpenLR location referencing used for information on all FRC 0-4 roads

New services: smarter real-time information

Automatic detection of road closures on highways

Road closure report Corrected by LIVE data input

HD Traffic Fusion

Automatic correction of road closures

Effect of change*65% more road closure messages

Effect of change32% of messages are corrected

10% removed completely

Applied changeBased on flow of real-time GPS probes road closure reports are verified and corrected if needed

Applied changeTriggered by the lack of real-time GPS probe data for highways road closure reports are created

* Measured effects of changes are given as an example for Germany, actual effects may differ from country to country

New Services: SPITS adaptive cruise control trials

Created in partnership with TNOTested on A270 between Helmond &Eindhoven.

2010 Experiments: V2V Only• 100 vehicles, two lanes • Control vs. 100% equipped• 17% improvement on flow

2011 Experiments: V2I• 70 vehicles, two lanes• Control vs. 10% automated• 4% improvement• Substantially lower collision

risk

New Services: Green Wave Service

On-board units support 3G and WiFi-p as connectivity solutions and communicate to traffic lights to give intelligent speed advice to the drivers.

• Develop a scalable system for green-light timing and consequent speed-to-green advise based on cellular connection.

• Insight into the acceptance and effectiveness of in-car Green Wave speed advice for drivers.

• Demonstrate improved traffic flow and fuel consumption for individual drivers by means of in-car applications.
