App Designed to Turn Lights Green for Cyclists Goes National

The app, developed by Sensys Networks, is meant for bicyclists specifically. It got its first taste of the real world starting in Santa Clarita, Calif., at the end of 2018, before going in for another test in Fort Wayne, Ind. The basic concept of the app is to connect a smartphone to an intersection’s Sensys FlexControl gateway via Bluetooth, starting when the cyclist is 300 feet away — the length of a football field. Once the intersection registers the cyclist’s approach, it sends a message via the app to let the person know. That can be either a text notification in the app or a vibration.
