MOBILE ROADSIDE SPEEDOMETER BOARD IN VESTFOLD COUNTY, NORWAY; EFFECT UPON SPEED

FARTSVISNINGSTAVLE I VESTFOLD; VIRKNING PAA FART

The report describes two experiments in Vestfold County, Norway, both using a roadside speedometer displaying speed to drivers. In the first experiment - on the road E18 - the drivers were warned about the measurement of speed by a sign some 1000 metres before the display. In the second experiment - on the road 310 - there was no previous warning of speed measurement. Speed was measured before, during and after the speedometer was in operation, and compared with recorded speed on reference road sections without such speedometers. The statistical analyses show that the speed was reduced by 2.0-6.8 km/h on E18 and by 1.2-6.1 km/h on road 310 when the display was in operation. The length of the road stretches where speed reductions were observed vary between 150-430 metres as a minimum.(A)
