New Signals Installations and Removals<br />
All of the follow ing steps are to be part of the installation process:<br />
• candidate site identification;<br />
• warrant study;<br />
• signal design;<br />
• signal installation; and<br />
• commissioning.<br />
The follow ing procedure should be follow ed w hen removing traffic signals:<br />
• information is to be provided to the public for 2 weeks prior to the removal<br />
procedure commencing;<br />
• signals are to be placed in a flashing mode for 1 or 2 days;<br />
• implement new form of control and mask traffic signals for a period of at least<br />
7 days;<br />
• undertake a w arrant study during this stage to re-confirm the removal process;<br />
and<br />

Maintenance Actions<br />
Although to a certain extent obvious, it is prudent to re-visit the consequences of<br />
maintenance deficiencies as it is listed in the South African Road Signs Manual:<br />
• the cost-effectiveness of good signal maintenance is beyond question. The<br />
traffic safety implications of malfunctioning traffic signals alone can justify the<br />
cost of keeping signals in proper w orking order;<br />
• the possibility of liability judgements against a road authority is also an<br />
important consideration in signal maintenance. Proper maintenance of traffic<br />
signals is of vital importance if liability is to be minimised;<br />
