A range of options were considered during planning for these intersections, including roundabouts.

Traffic signals were identified as the preferred option following an assessment of safety, operational and site constraints at both intersections.

Signalisation provides clear separation between conflicting traffic movements, reducing the potential for vehicle conflicts and providing safer turning movements for all road users.

Installation of a roundabout would require a larger footprint, involve potential property impacts, and create unbalanced vehicle movements. There were also challenges associated with constructing a roundabout on the existing steep grade at the Blackall Street intersection.

Overall, traffic signals were identified as providing the safest and most effective outcome for these intersections.

TMR understands community concerns about the proximity of the proposed intersections and potential impacts on traffic flow.

Traffic signals can be operated using different timing plans to respond to changing traffic demands throughout the day.

Signal optimisation ensures that intersection signals reflect current traffic conditions to optimise movements and increase the efficiency of the entire corridor.

As part of future design development, TMR will continue to assess how the proposed signals interact with nearby intersections to support safe and efficient traffic operation across the network.
