Smart phone app helps cut fuel use at red lights
, Sept 13: A
app that’s being tested by researchers at Princeton and MIT is set to help lessen a car’s
while at the red light.
Signal Guru, which can show
how fast or slow they can go to avoid stopping at the next red light, is geared towards fuel efficiency and lessening traffic congestion, Discovery News reported.
According to the researchers, if drivers avoid idling at red lights, fuel use is cut by 20 percent.
the smart phone
is mounted on the dash, the app uses the phone’s ability to connect to others who are also running it, as well as the camera, to keep track of signals.
Researchers tested the app in Cambridge, Mass., where fixed
are used, and in
, where signals adapt to traffic volume.
tests were off by two-thirds, and the adapting tests were one to two seconds away from complete accuracy.
As long as people use the app for its intended purposes, this app and others like it, when released for commercial use, could help lessen energy consumption. (ANI)
