A driving network is an integrated, cohesive set of roads and streets that enables people to drive to any destination in Yarra. We already have this network, but its usability is under threat from severe traffic congestion.
Preferred Traffic Routes
Medium and longer distance journeys take place on Preferred Traffic Routes (PTRs), a network that spreads across greater Melbourne, and supports higher speeds (50 to 80 km/h).
Arterials
Arterials branch out from Preferred Traffic Routes and lead to slower (30 or 40 km/h) and calmer streets within neighbourhoods.
Worsening congestion
The main problem with our driving network is that congestion is becoming severe, which impedes people’s ability to get around. The KPMG Melbourne Activity Based Model showed that some streets were at capacity in 2015, and that gridlock is likely on many streets before 2030.
Suggestions
We don’t have enough space to add more traffic lanes. Even if we could, this would only induce more traffic, and congestion would return.
Instead, we need to offer alternatives – footpath, bicycle and public transport networks – so that people who are willing to ‘have a go’ with other modes are able to, thus freeing up space on our driving network for those who need to drive. In other words, investing in walking, cycling and public transport will help make Yarra better for drivers.
Another way to reduce congestion is to impose decongestion charges, i.e. demand responsive driving charges, which encourage some people to change what time of day they travel, or to use other modes, thus freeing up road space for those who need to drive.
