Dutch experiences with route information panels
Which types of electronic route information systems are most widely used in the Netherlands?
Dynamic information panels can send road users varying messages. Several types of electronic route information panels are being used in the Netherlands. One type of Variable Message Sign (VMS), which provides information about the traffic distribution (e.g. tailbacks) along a particular route and suggests alternative routes to improve the traffic flow, is called Dynamic Route Information Panels (DRIPs) in the Netherlands. Sometimes they show the estimated journey times for specific routes. DRIPs display information across the entire width of the carriageway and can also display a general safety advice, for instance to wear a seatbelt. In 2004 there were more than 100 DRIPs in use in the Netherlands. In addition Matrix Signal Indicators (MSIs) are used in the Netherlands. These MSIs react to incidents or deviant situations that occur on motorways. They then indicate a speed limit of for instance 50 or 70 km/hour. Because there are more MSIs than DRIPs they are better suited for use in unexpected events; moreover, they can also give separate information for each lane.
