Transport infrastructure has such an impact on what kind of city we become that more democratic planning is long overdue. But public consultation is typically limited and focused on design issues.
The population growth is in the west, but most of the jobs are still in the city centre. Three major development proposals could help reshape Melbourne in ways that help overcome this costly mismatch.
Hobart is a smaller city with big city problems that have become an election issue. Recent growth is creating traffic congestion that affects productivity, residents' health and liveability.
Self-driving, shared, electric vehicles and increasing urban density represent four disruptions that will transform city life. But a transport utopia isn't a guaranteed outcome of their interactions.
One potential benefit of WestConnex, which remains untouched, is that it could relieve Sydney's city centre from cars and make it more pedestrian-friendly.
A comparison of Australian cities reveals cyclists and walkers are still very much a minority of commuters, despite the economic, health and environmental costs. Action on three fronts is needed.
The real challenge is finding appropriate ways to invest in public transport that will not only take pressure off the system but also support improved travel on all modes, including cars.
If the strategies we put in place to make cycling safer were taken up in earnest the result would often be chaos.
Australian cities generally don't allow pet dogs on public transport. Instead, owners need their own vehicle to travel with their dogs, and it's a surprisingly important factor in our car dependency.
Australians can see the impact of dockless bike sharing on the streets of their cities. The huge store of data collected about user journeys is less visible, but just as important.
The government claims figures showing the south gets more than the north are misleading.
Traffic congestion is the main cost that cars create when they use existing roads. Road use charges are a more efficient and fairer way to cover the cost and help ensure traffic flows.
A city-wide experiment suggests well-designed road use charges could ease congestion by encouraging people to drive at different times, take other routes or use other transport.
Cities around the world are starting to rethink the vast areas of land set aside for parking. The convergence of several trends likely will mean this space becomes available for other uses.
One of the most effective ways to reduce health inequalities across Australia is to design neighbourhoods that free residents from having to rely on cars for transport.
No matter whether competitive tendering or negotiation is used, operators that do not meet clear and transparent service benchmarks should be shown the door.
Traffic continues to increase, but more slowly than would have been the case if the reforms had not gone ahead.
The evidence suggests a small investment in cycling infrastructure, combined with less punitive policing, would enable more Australians to escape daily traffic congestion.
Australians are crying out for political leadership. One way our leaders can redeem themselves is by getting to work on a complete shake-up of how we pay for and use transport infrastructure.
Victoria offers lessons in the benefits of integrating metropolitan and regional planning, using regional rail to shrink distance and ease the pressures of growth on our big capital cities.
