§ Mr. PawseyTo ask the Secretary of State for Transport what action is taken to record systematically vehicle speeds on motorways.
§ Mr. Peter BottomleyAutomatic traffic counters, which also measure vehicle speeds, are being installed at 25 motorway sites. At present, speed data are being obtained from two of these sites; another eight should be supplying data by the end of the year, with the remaining 15 becoming operational in 1990.
These data will enable vehicle speeds, and trends in vehicle speeds, to be analysed by type of vehicle and time of day. It is unlikely that it will be possible to do such analyses until mid-1990 because of the need to have a sufficient number of sites supplying reliable, consistent, data.
