NOW AN APP TO BEAT UP TRAFFIC JAM

The app called SignalGuru predicts when a traffic signal is about to change, and the speed that should be driven when approaching an intersection in order to cruise through without stopping.

"The stop-and-go pattern that traffic signals create increases fuel consumption significantly," said Emmanouil Koukoumidis, the scientist behind the app.

When approaching an intersection, the camera on a driver's dashboard-mounted smart phone is activated, which detects when a signal transitions from red to green and vice versa.
Using this information, the app determines the speed that should be driven to avoid stopping at a red light on the cusp of turning green, or a green light just shy of turning red.
"It tells the drivers that 'if you drive at 30 miles per hour then you'll be able to cruise through without stopping,'" explained Koukoumidis, adding that the speed recommended is always within legal speed limits.
Currently the group is looking for industrial partners to commercialize the software. They also plan to implement other safety features, such as thresholds on deceleration, before making it accessible to the public.
