Traffic

No-one enjoys idling in peak-hour traffic, yet scientists have identified that a blood pressure spike during it doesn't come from frustration but from ultrafine particles flowing into the car. And the average 4.5 mm Hg spike lasts for an entire day.

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 order to optimize traffic flow, many autonomous vehicles communicate with one another and with traffic control systems. Scientists are now suggesting that an extra white light at intersections could help incorporate human drivers into the mix.

By exposing healthy adults to diesel fumes before having their brain activity imaged in an fMRI machine, researchers have shown how traffic pollution can impair brain function, offering evidence of the connection between air quality and cognition.

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.

Researchers at Northwestern University have come up with a new congestion-busting control algorithm for autonomous vehicles, demonstrating its capabilities via a swarm of tiny robots that can assemble into desired shapes within 60 seconds.

Elon Musk revealed over the weekend that a new arm of the tunneling venture, The Boring Company, is in the works for China, a place where his electric car company also happens to be making some inroads. ​​

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.

A new study has collected seven years of data from Colorado, Washington, and Oregon – three of the earliest US states to legalize marijuana – in order to offer a clearer insight into whether traffic fatalities increased after marijuana legalization.

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.
