Autonomous drones have already been used to deliver medicines and other small freight items.
Supply-chain experts see reliable data, STEM education and smarter regulation as essential for Australia to succeed in an increasingly automated world under pressure to be environmentally sustainable.
Ant colonies direct traffic flows of millions of individuals along the best routes – army ants even manage inbound and outbound lanes – but how?
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?
Citibike station in midtown Manhattan.
Dozens of US cities have launched bike-share programs in the past decade. There have been bumps – critics want wider access, and cities want bikes stored out of the way – but bike sharing is on a roll.
In the cockpit of an aircraft, the hierarchy between captain and co-pilot is strictly respected. At the risk, sometimes, of poor decisions being made.
Fuel economy and air pollution regulations have lowered pollution and pushed industry to innovate.

Where’s my bus?
Even in cities with good public transportation, some areas can be 'transit deserts,' where demand exceeds supply. Living in these zones makes it hard to access good jobs, health care and other services.
Buses are set to be replaced by private and autonomous vehicles – but it's not clear how society is going to deal with it.

Pedestrians ensure their safety by making eye contact with human drivers. Autonomous cars will have to communicate with nearby people in other ways.
When is it too hot to fly?
Major airports around the world will see more frequent flight restrictions in the coming decades because of increasingly common hot temperatures.
How will we react when cars start driving themselves?
How might we, and our nation's roads and highways, need to change as autonomous vehicles become more ubiquitous? We know a lot of the answers, but not all of them.
Sales of electric vehicles are growing fast, especially in Europe.
Shifting to plug-in cars wouldn't be enough to max out global oil consumption by 2040. But it could help make that happen if cities pitch in and ride-sharing doesn't crowd out public transportation.
Many Americans need reliable public transit to get to school or work.
Many Americans live in transit deserts – areas where demand for transit exceeds the supply. To fix these gaps, we need to find and map them so agencies can add transit options in the right places.
How can we ensure technology brings prosperity to us all?
Political and community leaders must act now to preserve the American middle class and adapt the US economy for the 21st century.
