The GreenRoad system looks simple from the outside: There’s a two-inch device on the dashboard that starts the day with a green light. If a driver brakes hard, swerves or turns recklessly, the light turns yellow. If the driver continues to drive erratically the light stays yellow. If it gets worse the light turns red. That’s it. But like a lot of apparently simple ideas, there’s a lot more going on under the hood.

GreenRoad was the brain-child of an Israeli entrepreneur who was run off the road one night by some wild kids. “If only their parents knew how they were driving…” he muttered to himself and the work on the company began. It morphed over the years from a consumer product to one aimed at commercial fleets. While the device is made up from mostly off-the-shelf products like a GPS chip, accelerometer, a CPU, mashed up with Google maps and a dashboard-like management portal, it took a good three years of hardcore R&D to build.
