In Sydney, a 'latte line', that runs from the airport to Parramatta and up to the northwest, divides white-collar jobs from blue-collar jobs. This perpetuates inequality.
It's easy to be cynical about charity drives like the Vinnies CEO Sleepout. Are they just PR stunts or can they make a difference beyond fundraising? Our study shows they can, and they do.
The standards we use today were designed to help avoid the overcrowded housing that blighted cities in the past. But severe overcrowding is again on the rise, so what needs to be done?
The combination of higher-density living and increasing cultural diversity means we need to think about how to build social cohesion and make the most of the opportunities of apartment living.
Australia has guidelines for designing safe parks, but the stories of many women show these are not enough. We must involve women in co-designing these shared public spaces.
The largest cities in Australia and the US are both the richest and the most likely to push out low-income earners. Having cities of all sizes will increase people's choices of where to live and work.
Laws providing for safe access protect the dignity and safety of staff who need access to their workplace and women who need access to health-care services without harassment and intimidation.
Dockless or stationless bike sharing is risky business, relying a bit too much on common decency. Bike sharing schemes can work, but they may need to forego user convenience for bike safety.
Regional areas are expanding, and yet not enough attention is being paid to improving rail access to capital cities. This affects the liveability of the areas.
The NDIS has started to reduce the admissions of young people with disabilities to aged care facilities, but more than 6,000 are still waiting for more suitable accommodation.
Marketers once liked to think they could virtually steer people through shops and malls. But it appears shoppers' movements, possibly driven by primal instincts, aren't so easily directed.
Collisions at intersections between motor vehicles, cyclists and pedestrians cause many deaths and injuries. Design that considers how each group approaches intersections improves everyone's safety.
Everyone doesn't simply wait their turn at traffic lights. Signals are set up to enable a 'green wave' for cars and adjust to heavy traffic, making walkers wait longer no matter how many there are.
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.
Insects aren't known for having big brains, and slime moulds and fungi don't have any. So how do they solve challenges that test the ingenuity of human transport engineers?
There's no such thing as a one-size-fits-all plan for sustainable, healthy urban living. Urban diaries help identify what works – and doesn't work – for tropical cities like Cairns or Townsville.
One problem with Airbnb is that it isn't transparent about how many properties are truly 'shared' and how many are just part of a letting business. Regulators need to know that to manage the impacts.
Businesses are weighing up the costs of queuing and using innovative ways to minimise these costs by doing away with queues.
Cities are expanding upwards and downwards, as well as outwards. With urban density also increasing, moving people efficiently around the city, often using ageing infrastructure, is quite a challenge.
Western Sydney Aerotropolis is Australia's first publicly funded airport project in more than three decades. It has bipartisan support, but its fate also depends on getting the policy settings right.
To deliver better housing for health, we must go back to what we know works, to the proven evidence-based solutions for design, construction, delivery and maintenance.
Research into food sharing in Melbourne shows these networks are highly productive and produce many benefits. But policy and the law have yet to catch up.
