An increase in the use of self-driving cars will change parking infrastructure in cities, and hopefully result in more colourful character neighbourhoods.
Urbanisation is the main reason for rising temperatures and water pollution, but receives little attention in discussions about the health of water streams, reefs and oceans.
In the election bidding wars, parties commit billions to transport projects, often before all the work needed to justify these has been done. More cost-effective alternatives hardly get a look-in.
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.
TfL's money troubles worsen, as passenger numbers fall for the first time in two decades.
The risk of urban flooding is rising. Overall, residents and municipalities are ill prepared, but there are steps homeowners can take to protect themselves.
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.
Scholars and planners have long pointed out the need in Australia's big cities for democratic governance structures that operate at a citywide scale. Now Infrastructure Australia has weighed in.
Urbanisation has been a well-established trend and for some countries will continue to be. But some others experience the opposite, resulting in underused and abandoned infrastructure.
Traditionally, new communities first get hard infrastructure – schools, hospitals, transport – and 'soft' social infrastructure comes later. Liveability and public health suffer as a result.
Drains take up precious but inaccessible open space in our cities. Converting these to living streams running through the suburbs could make for healthier places in multiple ways.
The rail project may well help get more commuters into the CBD, but offers few benefits for the parts of the broader metro area where most population growth is occurring.
A variable special rate on new residential housing developments in selected centres could be used to create a local incentive to supply more affordable dwellings at higher density.
Australia should follow the lead of other nations like New Zealand and Switzerland and increase the charges for heavy vehicles on roads, proportionate to the amount of wear and tear they cause.
There are three key principles: prevent risk, evacuate users and minimise damage – in that order.
The highly politicised nature of the NBN has led to a lack of transparency that makes it even harder to fix the mess that has been made of this vital national infrastructure.
The light rail project pushed up property values within 800 metres of the stations by over 30% from 1996 to 2016. Gains on this scale offer a potential source of finance for public transport.
The trillions of dollars spent on infrastructure demands democratic transparency and accountability. This applies to both the investment and to the effects on cities, societies and the environment.
Suburban areas feel infrastructure stress most acutely. Having to deal with severe inadequacies, suburbs offer fertile ground for infrastructure experimentation and innovation.
Long-term privatisation contracts, most of them closed to scrutiny, lock urban infrastructure into 20th-century formats unsuited for a climate-threatened planet.
