Ramp signals control traffic flow and improve safety on freeways by staggering the volume of vehicles entering the freeway.

Freeway to freeway ramp signals operate in a similar way, controlling traffic flow when large volumes of traffic from two different freeways meet. Electronic signage and traffic signals space out vehicles, making merging safer and faster, resulting in less congestion and fewer collisions.

Freeway to freeway ramp signals will be rolled out from late June to August 2018 at the following interchanges:

• M80 Ring Road Greensborough-bound to Calder Freeway city-bound
• M80 Ring Road Greensborough-bound to Tullamarine Freeway airport-bound
• M80 Ring Road Altona-bound to Tullamarine Freeway airport-bound
• M80 Ring Road Altona-bound to Tullamarine Freeway city-bound
• Calder Freeway city-bound to M80 Ring Road Greensborough-bound
• Calder Freeway outbound to M80 Ring Road Altona-bound
• Eastlink to Monash Freeway inbound
• Eastlink to Monash Freeway outbound
