Part of Dutch Project: Brabant In-Car II
In the pilot Green and blue wave we want to examine how it is for you as road user to receive green and blue waves information via the navigation system in your car. For this project we used the Eisenhowerlaan in Eindhoven.
The green wave is well known in the Netherlands, if you keep at a certain speed, you are assured of green light at the next intersection. The system is often used but usually the road users are not informed. Normally it works when you simply maintain the speed limit. At some locations the best speed to the next green traffic light is shown via electronic road signs. But the aim of this trial is to offer the road user this information in-car, on the navigation system. When you keep the advised speed on your display, acceleration and deceleration can be reduced to a minimum. This saves time and fuel.
The blue wave is a warning for a police car, ambulance or fire truck with sirens and flashing lights coming from behind you. Normally road users must rely on their hearing to know that a service is approaching. The problem is that it is often difficult to determine from which direction the sound is coming. Many road users hear the siren at the last moment due to loud music or other noise. In this test the driver will be notified via the navigation system and only if the emergency approaching from behind. This allows drivers to make room for the ambulance or the fire brigade on time.
How does it work? The special feature of this test is not only the in-car' component, but also the underlying technology: Radio Dynamic Speed Advice, RDSA. As its name suggests, this involves radio signals: there are small radio transmitters and receivers. The stations are set up along the route. They are linked to a simple traffic control center that knows at what point the light turns green, and if there is an emergency approach. A small in-car receiver picks up the signal from the transmitter. The advantage of RDSA is that it is a proven, existing technology and that it is cheap and easy to roll out.

Details of Field Operational Test
Start date and duration of FOT execution
September 2012 – November 2012
Eisenhouwerlaan, Eindhoven, The Netherlands
Show that radio signals can be used to receive “green” and “blue” wave information.
Keep the costs of the system very low for the end-user.
Show that this system makes the car-driver more aware of his behaviour so that he is willing to adapt his behaviour which results in a better traffic flow.
The radio signals can be used to receive “green” and “blue” wave information.
Drivers can anticipate on the given advice on the navigation system.
The blue-wave information can potentially be rolled out.
The position of the sender of the radio signals is crucial for the success of the product.
