3.4Managing conflict points#

Traffic management may be required at conflict points, especially where a change in priority is required (due to event participants or spectators needing free passage of movement) or where general traffic still has priority and management of event participants is required. Scenarios are presented in the following figures to illustrate the use of advance warning signage and manual control of traffic using traffic controllers and ETMs in the following situations:

unsignalised intersection (four-way)
roundabout (four-way)
pedestrian / cyclist crossings (mid-block and intersection), and
through road (two-way).

When considering these scenarios, it is important to note that:

the figures are illustrative only and a TGS showing the traffic control devices required and spacing / set-out arrangements must be designed for the site-specific situation by a TMD – examples of how to integrate other Queensland MUTCD traffic signs into these illustrations are provided in Appendix A
requirements relating to the use of traffic controllers can be found in the QGTTM Part 7 and the Traffic Controller Accreditation Scheme Approved Procedure (TCASAP)
requirements relating to the use of ETMs can be found in this ETMDG and the Events Traffic Marshal – Special Events Approved Procedure
requirements relating to the signing of detours can be found in the QGTTM
general traffic may need to be restricted along the event route and/or
participants may be required to travel in a convoy or follow special instructions for participating in the event (including the road rules).

Figure 3.4(a) – Unsignalised intersection: right turn from through roadp. 38

Event participants turning right from a through road onto a side road where it is desired to provide priority to the event participants and ensure that vehicles do not attempt to turn from the side roads while event participants are present. Use of traffic control to hold side road approaches and opposing through road approach.

Notes

Where frequent stoppages of vehicles are required, the impacts on traffic operations and/or vehicle queueing should be considered. Pedestrians attempting to cross the road that event participants are turning into or from may also need to be controlled. Controls may be put in place at the intersection to manage traffic travelling in the same direction as event participants so that traffic impacts on event participant movements are minimised. For example from following / overtaking traffic or traffic waiting and queued at the intersection to turn. The END EVENT signs along the continuing event route will be replaced by EVENT IN PROGRESS signs where the event is still continuing in this direction. The EVENT AHEAD signs along the continuing event route will not be required where the event is continuing in this direction and where all road users have passed an EVENT AHEAD sign previously.

Figure 3 4(b) – Unsignalised intersection: right turn from side roadp. 39

Event participants turning right from a side road onto a through road where it is desired to provide priority to the event participants and prevent minor road vehicles from attempting to turn between gaps in event participants. Use of traffic control to hold side road approach and opposite through road approach.

Notes

Figure 3.4(c) – Unsignalised intersection: left turn from side roadp. 40

Event participants turning left from side road onto a through road where it is desired to provide priority to the event participants and prevent side road vehicles from attempting to turn between gaps in event participants. Use of traffic control to hold side road approaches and opposite through road approach.

Figure 3.4(d) – Unsignalised intersection: through from side roadp. 41

Event participants travelling straight from side road across a through road where it is desired to provide priority to the event participants and prevent minor road vehicles from attempting to turn between gaps in event participants. Use of traffic control to hold side road approaches and opposite through road approach.

Notes

Where frequent stoppages of vehicles are required, the impacts on traffic operations and/or vehicle queueing should be considered. Pedestrians attempting to cross the road that event participants are using may also need to be controlled. Controls may be put in place at the intersection to manage traffic travelling in the same direction as event participants so that traffic impacts on event participant movements are minimised. For example from following / overtaking traffic or traffic waiting and queued at the intersection to turn. The END EVENT signs along the continuing event route will be replaced by EVENT IN PROGRESS signs where the event is still continuing in this direction. The EVENT AHEAD signs along the continuing event route will not be required where the event is continuing in this direction and where all road users have passed an EVENT AHEAD sign previously.

Notes

This arrangement can be used for any movement of participants through a roundabout. Additional traffic management measures may be required at multi-lane roundabouts. Where frequent stoppages of vehicles are required, the impacts on traffic operations and/or vehicle queueing should be considered. Pedestrians attempting to cross the road that event participants are turning into or from may also need to be controlled. Controls may be put in place at the roundabout to manage traffic travelling in the same direction as event participants so that traffic impacts on event participant movements are minimised. For example from following / overtaking traffic or traffic waiting and queued at the roundabout to turn. The END EVENT signs along the continuing event route will be replaced by EVENT IN PROGRESS signs where the event is still continuing in this direction. The EVENT AHEAD signs along the continuing event route will not be required where the event is continuing in this direction and where all road users have passed an EVENT AHEAD sign previously.
