Through-traffic on a provincial road can suffer from signalised intersections. A green wave where the signalised intersections are coupled is an ideal situation for through-traffic. But how will the driver know which speed he has to drive in order to benefit from the green wave? In this situation an in-vehicle driver assistance system and variable message signs can play a role. In this Master thesis research project an in-vehicle system and variable message signs are used to give the driver a personal advisory speed. If the driver decides to drive the advisory speed he will benefit from the green wave. This research project focuses on driver behaviour and the acceptance of the two systems.

How will drivers respond to this? Will they follow the advice or will they ignore it? And will they accept the system which gives them an advisory speed? The effects of coupled signalised intersections on the driving behaviour which is influenced by the way the driver is given information about an advisory speed will be examined.

In order to determine these effects the driving simulator from TNO in Soesterberg will be used. The subjects will drive on a provincial road with signalized intersections in the virtual environment. For measuring the effects on driving behaviour there will be three conditions. The first condition is where the driver won’t get an advisory speed, in the second condition he will get it via an in-vehicle system and in the third condition variable message signs are used. When the driver gets an advisory speed he can decide if he will drive the advisory speed or his own chosen speed. In the case where he drives the advisory speed a green wave is guaranteed.
