New technologies, new opportunities

New technologies that can make speed management more intelligent and flexible emerge rapidly. They are based on digital maps in relation to vehicle positioning information, e.g. through GPS. They are also based on the possibilities of vehicle-roadside communication and the automatic detection of the actual traffic, road and weather circumstances. Some systems are already available and likely to be introduced progressively. With respect to speed management, there are interesting and promising developments related to ISA and dynamic speed limits.
