During the period 1999-2002 the Swedish National Road Administration conducted a comprehensive road information project which included a large-scale trial involving intelligent speed adaptation in urban areas. Sever thousand vehicles were equipped with voluntary supportive and information systems to help keep drivers from exceeding the speed limit. The systems were tested in Borlange, Lidkoping, Lund and Umea where the local authorities were responsible for running the trials in the respective municipalities. Over the three years of the project, the Swedish National Road Administration provided SEK 75 million in funding and was also responsible for the overall coordination of the technology involved as well as for evaluating the comparative advantages and disadvantages of the various systems.
