Researchers AI in connected cars eased rush hour congestion

News Summary

  • Then, as traffic clears, the drivers accelerate too quickly, causing more braking and yet another jam.“We know that one car braking suddenly can have a huge impact,” Work said.Last week’s experiment showed that a few cars driving slowly and steadily could have an impact as well, for the better.
  • In the experiment, the adaptive cruise control was modified to react to the overall traffic flow — including what was happening far ahead — using artificial intelligence.The cars’ decision-making occurred on two levels, Work said.
  • Human drivers just don’t do a good job of navigating dense traffic conditions, but an experiment using artificial intelligence in Nashville last week means help could be on the way.
  • That led to a 40% increase in fuel efficiency and a 14% increase in distance driven.Researchers are still crunching the numbers on last week’s experiment, but Work said it “demonstrated that these jams can be reduced through the novel automated vehicle technologies we developed.
  • The researchers were able to evaluate the effect the connected cars had on morning traffic flow using a special 4-mile stretch of I-24 outfitted with 300 pole-mounted sensors.
  • It’s unquestionable that enhanced automotive technology can significantly reduce phantom traffic jams when implemented at scale.”Still, he cautioned that the technology is not going to suddenly eliminate congestion.
