DRIVING SPEEDS ON 80 AND 100 KM/H ROADS (II). REPORT ON NATIONWIDE REPRESENTATIVE SPEED MEASUREMENTS FOR THE PROJECT 'MONITORING DRIVING SPEEDS' ON 80 AND 100 KM/H ROADS, PHASE 3, SECOND MEASUREMENT

The Transport Research Center (AVV) of the Directorate General for Public Works and Water Management commissioned the SWOV Institute for Road Safety Research to carry out speed measurements on 80 and 100 km/h roads in twelve Dutch provinces. These measurements were executed in the year 1994. The first series of measurements was completed in 1992. The SWOV's design of the network of measuring spots was used for the selection of measuring spots. The measurements were carried out on seven road types outside built-up areas. Mobile radar systems were used. The results of the three most important road types are: (1) Roads with limited access and a 100 km/h speed limit show an average speed of 86 km/h, and a speed violation of 18%; (2) other important roads with a 80 km/h speed limit show an average speed of 76 km/h, and a speed violation of 35%; and (3) roads narrower than 5 meter and with a 80 km/h speed limit show an average speed of 71 km/h, and a speed violation of 25%. The results of the measurements provide both a country wide representative and a regional indicative image of the driving speeds. The report also shows a decrease of the average speed level in 1994 compared to the level in 1992. See also IRRD 860653.
