Samenvatting
Congestion and traffic accidents occur relatively frequently on the primary road network of The Netherlands. At present the Dutch road authorities are making every attempt at finding solutions to reduce congestion on the road network. Examples of these attempts include the use of the emergency lane as a traffic lane and dynamic route information systems. Also being investigated is the use of narrow lanes to increase carriageway capacity. This could lead to improved traffic flow although it adds to the complexity of the driving task and possibly to the detriment of road safety. (Author/publisher)
