Missing evidence base for big calls on infrastructure costs us all

Billions of taxpayer dollars are committed before all the evidence for, and against, infrastructure projects is in. As well as missing business cases, basic rules of economic modelling are broken.
Whether it’s birds in a flock or drivers in traffic, agent-based modelling can describe complex phenomena by applying a simple set of rules to each individual’s behaviour. Barry Sweet/EPA

Traffic is complex, but modelling using deceptively simple rules can help unravel what’s going on

By identifying and applying the key rules governing the behaviour of each individual, agent-based modelling offers insights into complex phenomena like traffic jams and flocking.

Growth pains and gridlock come to Hobart, and building more roads is not the best way out

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.
Much of the traffic using Sydney’s Anzac Bridge and, in the distance, Harbour Bridge is travelling through the city centre, not to it or from it. Rob Roggema

This is how WestConnex can deliver Sydney a better city centre

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.

Delay in changing direction on how we tax drivers will cost us all

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.

City-wide trial shows how road use charges can reduce traffic jams

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.

People take to their bikes when we make it safer and easier for them

The evidence suggests a small investment in cycling infrastructure, combined with less punitive policing, would enable more Australians to escape daily traffic congestion.

Impending traffic chaos? Beware the problematic West Gate Tunnel forecasts

Melbourne's proposed road project relies on assumptions that inflate estimates of the traffic the new link will carry – but other choices about the future of transport are open to us.

Make housing affordable and cut road congestion all at once? Here’s a way

A combination of transit-oriented centres, inclusionary zoning and a special rate on land instead of stamp duty could make housing more affordable by cutting congestion, development and travel costs.

If you’re serious about affordable Sydney housing, Premier, here’s a must-do list

The new NSW premier is right to identify housing affordability as a priority for the people and economy of Sydney. It's not just housing supply that's the problem – action is needed on many fronts.
Will the reality match the hype that’s promised from a future with driverless cars? Shutterstock/Karsten Neglia

A future world full of driverless cars… seriously?!

Driverless cars are the future, right? Wait. While things would be simple if our roads were 100% driverless, getting there is anything but. And planning for roads shared by robots and humans is hard.
Road user pricing would encourage people to take non-essential trips at a different time, or not at all. thomasthethinkengine.com

Road user charging belongs on the political agenda as the best answer for congestion management

Charging people to drive has been the dream of policy wonks – serving politicians tend to see it as political poison. So when federal minister Paul Fletcher raises it, that's a step forward.

How to make cities work better – here’s what the government needs to do

Bigger cities increase wages, output and innovation, but also problems of congestion and pollution. Congestion charges can minimise these problems by dramatically improving traffic flows.

If the people can’t get to their jobs, bring the jobs to the people

Sydney, as a whole, is lurching toward an urban structure where its transportation problems are impossible to solve. The only alternative is to create new centres of employment.
