Dash-Mounted Smartphones Help Drivers Avoid Red Lights

A new application uses visual data gathered by a network of dashboard-mounted smartphones in multiple cars to tell drivers the optimal speed they should travel to avoid having to sit at red lights. Researchers at MIT and Princeton developed SignalGuru and tested it in Cambridge, Massachusetts, and in Singapore. They said the application helped the Cambridge test drivers reduce fuel consumption by an average of 20 percent. They said their technology could be used for other commuter-related applications, such as the determining the locations of available parking spaces or city buses’ travel rates.
