Safe performance of other activities in conditionally automated vehicles: Automated Lane Keeping System

The Automated Lane Keeping System (ALKS) is designed to keep a vehicle within its lane while controlling its speed for long periods without intervention from a driver. Intended for use at low speeds on expressways, the system lets a driver perform other activities while the vehicle is moving. The authors performed a literature review to find what activities could be safely performed by a driver in a partially automated vehicle using ALKS. The review discovered recent research results based mainly on driving simulator studies. The absence of a protocol for measuring driver attention and performance made comparisons difficult but patterns emerged from the literature. These themes include the increased risk posed by a driver’s engagement with handheld devices, and activities on devices that demand visual engagement. Some of the risk can be lessened by enforcement of existing legislation, and also by the current ALKS specification requiring a Driver Availability Recognition System to ensure that the driver maintains a minimum level of alertness while being ready to retrieve control of the vehicle. But at present, what drivers can do with in-vehicle controls, and how the Driver Availability Recognition System is implemented, is mainly decided by manufacturers and software developers. The authors also considered the use of ALKS at higher speeds and as an Advanced Driver Assistance system, but significant risks exist with both of these. Further research is needed to establish what would be safe in these scenarios.
