Which of the following most accurately describes the problem?

PAA PORTABLE skid-resistance tester and a device for automatically weighing vehicles in motion are two of a number of pieces of equipment which will be on show at the Road -Research Laboratory during its open days, May 15

and 16. .

Both the Materials and Construction Division, including the Colonial Section, at Harmondsworth, and the Traffic and Safety Division, at Langley, will be.open to visitors.

The automatic weighing device can be set into a road to provide information of the magnitude and frequency of occurrence of vehicle wheel loads. It comprises a small weighbridge which rests on four load cells Carrying resistance ,strain gauges. Electrical output is• proportional to wheel load -(as it passes over) and actuates a fast-response mirror galvanometer. The light spot sweeps across 10 equally spaced photo-cells, and thus the number of loads in each of 10 weight levels is recorded.

At Langley, visitors will see a number of varieties of young shrubs growing in the grounds. These have been planted to provide the Laboratory with information on their protective value on road verges against crash impact. They will alsd be examined to discover which are the best varieties to plant down the centre of • a dual carriageway as protection against

dazzle from headlights.
