Traffic

Hangzhou is the latest city in China to take traffic control to a new level, rolling out its AI-powered robot police officer to direct vehicles and pedestrians at major intersections and issue polite warnings to law-breakers.

Most fully autonomous cars are being deployed in commercial settings, such as those used by driverless-ride providers like Waymo. However, a new company called Tensor plans to bring an L4 robocar to consumers next year, and it looks damn impressive.

So one night a tractor trailer jackknifes and flips in front of me on I-80 in a shower of sparks. I stop to help, and the guy pops out like Chatty-Cathy, still talking on the phone like nothing happened. That’s when I decided to get a dashcam.

Three weeks after one of Waymo's autonomous vehicles drove itself into a telephone pole for no apparent reason whatsoever (prompting 672 cars recalled), Waymo has released a statement saying its AVs are still 200 to 350% better at avoiding crashes than humans.

A new modular mobile flyover bridge allows vehicles to drive overtop of stretches of highway roadwork, instead of waiting to go around them. Known as the ASTRA Bridge, it's intended to make life easier for motorists and safer for roadway workers.

Through its Maps app, Google has access to a monster trove of daily traffic data – and it's using it to provide cities with free, AI-optimized traffic signal timing suggestions that could reduce stop/starts by 30% and intersection emissions by 10%.

In order to optimize traffic flow through city streets, municipalities often install car-counting cameras or other sensors at a few set locations. A new study, however, suggests that using existing bus-mounted cameras may be a better way to go.

In a smart and connected world, it's amazing how dumb our traffic lights can be. A new Melbourne project uses AI to crunch an unprecedented amount of live and historical data, hoping to optimize multi-mode traffic flow and influence behavior.

Ordinarily, traffic lights change color in response to predetermined rules and induction loop sensors embedded in the road. According to new research, however, making those lights artificially intelligent may keep traffic flowing faster and smoother.

Weekday travel times in the Golden Gate city increased a shocking 62 percent between 2010 and 2016. A growing number of studies are finding that ride sharing services are chiefly to blame The latest ran simulated traffic models with and without ride shares to determine how much impact they make.

Vehicle-to-infrastructure (V2X) communication will form one of the pillars of the self-driving car revolution - but it could offer benefits to human drivers in the interim, like this prototype system designed to help drivers get green lights wherever they go.

​​The Boring Company was conceived as a solution to LA’s traffic woes, and the first people to benefit from its forward-thinking tunnel networks may be the city’s sports fans. The company today announced a proposed transport link between the LA Metro and Dodger Stadium.
