TRAFFIC SPEEDS ON STEEP GRADIENTS ON RURAL SINGLE- CARRIAGEWAY ROADS
The article describes a study of vehicle speeds on steep sections of two roads having one carriageway. In one case there was no lane for slow-moving large vehicles, and in the other case a third lane was provided. When there was no crawler lane 32 per cent of cars were forced to form queues behind slow-moving heavily laden lorries; average speeds of these cars were about 55 percent lower than those of cars which could travel unhindered on the gradient. These speed restrictions did not occur on carriageways where a third lane was provided. /TRRL/
