The AVV - Transport Research Centre of the Dutch Ministry of Transport, Public Works and Water Management is looking to improve the effectiveness of Dynamic Traffic Management (DTM). A possible solution is the improvement of route information by presenting it in a graphical manner as opposed to the currently used alphanumeric style. Advantages of this way of presenting information are: more information can be given, complex information becomes easier to understand and information relevant to motorists with different destinations can be presented simultaneously. Research has shown that it is possible to safely implement graphical route information panels (GRIPs) with positive results. The so-called Route Information System (RIS) concept, designed in the private sector, consists of coherent entities of information panels: ring road and road section panels with regular variable message signs (VMSs) and sign posting. This concept will be illustrated in this paper as well as an intended field operational test (FOT). An overview of international state-of-the-art GRIPs and developments in the field of graphical route information, such as in the German MOBINET project, is given.
