THE SPEED LIMIT EXPERIMENTS ON PUBLIC ROADS IN FINLAND

NOPEUSRAJOITUSKOKEILUT SUOMEN YLEISILLA TEILLA

The speed limit experiments in Finland continued from 1962 to 1978. A summary of the results of these experiments is presented in this report. In the 1960's temporary general speed limits were applied several times. During 1969-73 an experiment with recommended road-section speeds, and after 1973 with compulsory speed limits, were carried out. The last mentioned experiment was extensive even when compared internationally. The investigations proved that the number of accidents decreased the more the speed limits managed to reduce the speed which was a function of the relative level of the speed limit. Too high a speed limit could also raise the level of speeds and increase the number of accidents. That was the case for instance in adverse weather conditions on slippery road surfaces. In the report alternative goals for the speed limit system are presented and the decision making concerning the speed limits reviewed. The report will be published in English. (TRRL)
