REDUCTION OF MAXIMUM SPEED LIMIT FROM 110 TO 90 KM/H DURING THE SUMMER OF 1979. INFLUENCE ON SPEED AND FUEL CONSUMPTION
Sänkning av högsta tillåten hastighet från 110 till 90 km/h under sommaren 1979 : effekt på hastighet och bensinförbrukning
This report presents the results of speed measurements and calculations on fuel savings in Sweden during the summer of 1979. During the period 21 June - 15 October the speed limit was reduced to 90 km/h on the roads, earlier limited to 110 km/h. The speed measurements show that the average speed for cars on motorways decreased by 12 km/h (from 107 to 95 km/h) immediately after the reduction of speed limit. The reduction remained until August while the average speed in September and October had increased by 5 km/h to 100 km/h. On highways with a speed limit of 110 km/h the average speed decreased by 7 km/h (from 97 to 90 km/h). Also this decrease remained until August. On roads always limited to 90 km/h the average speed decreased by 2 km/h (from 89 km/h to 87 km/h) during the period. The result of the calculation of the fuel saving points to the fact that the reduction of the speed limit has lead to a fuel saving of 12 to 29 million litres during the period. (TRRL)
