Abstract
Speed limits have been very effective in reducing accidents. Fixed speed limits at all times are probably most effective in good road conditions and slightly less so in adverse ones. In some cases, however, speed limits can encourage excessive speeds if they do not match prevailing conditions. This is also true – perhaps even more so – of variable speed limits. In 1997 a joint 2-year experiment was launched by the Ministry of Transport and Communications and the Finnish National Road Administration, in which speed limits would be changed according to the season of the year. Speed limits would be raised in summer and lowered in winter. Following good experience with the latter, coverage of lower wintertime speed limits was gradually extended. Higher speed limits in summer have not been used since the experiment. The effects of lower speed limits in winter both during and after the experiment will be presented to discuss the role of seasonal speed limits in speed management.
