Driver Alertness Warning

The system detects erratic driving based on weaving behavior within the driving lane. OnLane computes a "Driver Alertness Index" based on driving performance, and alerts the driver when it falls below a certain threshold. DAW warns the driver by providing an intermittent warning tone when it detects erratic driving or weaving within the driving lane. The alert terminates when driving performance improves, or when the key is cycled.
