MARKING OF EDGE LINES ON NARROW PAVEMENTS

Currently the Australian standard (as 1742) dealing with traffic control devices for use in Australia permits the use of edge lines on two-lane, two-way pavements that are at least 6.8M wide. The reasons for not extending their use to narrower pavements are somewhat unclear but appear to eminate from considerations of cost and accidents. This paper outlines the results of trials conducted on two-way pavements 5.5M wide, which is essentially the minimum width for two-way operations. The results indicate that there are definite economies to be derived from the marking of edge lines on these roads, as savings in shoulder maintenance costs outweigh painting costs. Statistically significant accident data could not be obtained. However the presence of edge lining caused vehicles to travel further away from the centre of the road and this itself may lead to a reduction in head-on type accidents by increasing the lateral separation between approaching vehicles. /TRRL/
