SUMMARY OF VARIOUS STUDIES OF SPEED LIMIT EXPERIMENTS

SYNTHESES DE DIVERSES ETUDES SUR LES EXPERIENCES DE LIMITATION DE VITESSE

This report analyzes speed limits in Germany, the USA & in France. In Germany, the 100 km/h speed limit resulted in a decrease in the number and severity of accidents outside built-up areas, no hindrance to traffic was observed. In the USA, the 55 miles/hr limit led to a reduction of 11% in fatalities. In France, experiments conducted in March 1969 (100 km/h) and April 1970 (110 km/h) led to a marked reduction in the number of accidents, especially fatalities. The simultaneous measures taken in July 1973 which consisted of a general speed limit of 100 km/h and of the compulsory use of safety belts in rural areas, led to an overall differential improvements of 8,4 and 11,6% as regards fatalities. Measures taken in December 1973 lowered the maximum speed to 90 km/h and retained the compulsory wear of safety belts. The average differential overall improvement as regards fatalities was between 21,7% and 24,9% compared to control conditions without speed limit. /TRRL/
