It's annoying when your bus route gets off schedule or when buses bunch together. Why has it taken engineers so long to fix the problem?
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.

Combining machine learning, artificial intelligence and autonomous vehicles could revolutionize how people with disabilities get around their communities.
Ride-hailing app drivers – partners or exploited labour?
Using technology and rhetoric, ride-hailing companies manage to dictate drivers while simultaneously creating the illusion of equal relation.
