Earlier a broken simulated line (using nonreflective raised pavement markers) was used as an L2 lane line. The RTA has discontinued its use. Noise impact must be taken into account when considering the use of profile linemarking. Refer to Section 5.6 for more details on profile linemarkings. 5.2.5.3 Applications Application of enhanced lane line (L2) is illustrated below: Figure 5.6: Profile lane line (L2) 5-8 Version 1.5 UNCONTROLLED WHEN PRINTED

5.2.6 Profile linemarking<br />
5.2.6.1 General<br />
Profile linemarking is a thermoplastic line, consisting of raised ribs at regular<br />
intervals. These markings provide a more durable marking, enhanced<br />
visibility and an audio-tactile warning to the motorists.<br />
Figure 5.7:<br />
Raised ribs across profile linemarking<br />
This section provides guidance on the use of profile linemarking for marking<br />
longitudinal lines while preserving the safe use of roads by all road users<br />
including cyclists, pedestrians and motorcyclists.<br />
5.2.6.2 Benefits<br />
The profile linemarking provides:<br />
(a)<br />
(b)<br />
An audio-tactile effect to motorists, should they stray from the<br />
carriageway and run onto the marking due to fatigue<br />
Enhanced visibility during adverse weather conditions, especially at<br />
night<br />
5.2.6.3 Types<br />
Currently two different patterns are available, designed to have a raised<br />
profile. They are:<br />
