• Positioning of Signs and Devices AGTTM – Part 6 – Section 6.5
 Signs and devices should be positioned and erected so that:                                        Traffic controllers must ensure that they have a clear escape path to a non-traffic

  End of Queue calculations are conducted to ensure that pre-warning signage may be
  placed in advance of the expected end of queue position once traffic is held by traffic
  controllers. The calculations are based on traffic volumes and hold times.                      • Signs warning of works personnel

The general procedure for setting up a site is to:                                                  have left the work area or are no longer visible to traffic.
1. locate the work area using GPS, landmarks, side streets, chainage
2. install devices as outlined in the TGS for side streets first
3. install devices as outlined in the TGS for the non-working lane (un-affected direction)        • Provision for pedestrians and bicycles - AGTTM – Part 3 – Section 3.10
4. install devices as outlined in the TGS for the working lane (affected direction) to complete     Where pedestrians, including school children and people with disabilities or visual

with AGTTM Part 3.                                                                                  for pedestrian or bicycle traffic that were existing prior to the works.
        In addition to providing adequate traffic control and guidance at a static work site
        the safety of road users will be enhanced by ensuring that the work site is
        managed in such a way as to cause the minimum amount of inconvenience to
        traffic movement. Works should be arranged to minimise -
         (i) disruption of established traffic movements and patterns;
         (ii) interference with traffic at peak movement periods;
         (iii) interference with public transport services; and
         (iv) the amount of road closed to traffic at any one time.

     Delineating devices (e.g. traffic cones, bollards, post mounted delineators) should
     generally be placed 1 m clear of the travelled path where practicable. However,
     traffic cones and bollards may also be used to define the edge of the travelled path
