SAFETY IMPLICATIONS OF IN-VEHICLE TECHNOLOGIES
Brookhuis, K., University of Groningen, Netherlands
In the present era it is technically feasible to support the error-prone driver by means of electronic driver support systems that provide information and / or support. Some of these systems just provide information, such as route guidance and navigation, or they warn in case of likelihood of longitudinal or lateral collision. In these cases the driver can choose to adopt or ignore the advice, which seems fairly harmless. Nevertheless an additional task over the primary task of driving the vehicle safely, is a case of additional mental workload and therefore increases accident likelihood. Recent technological developments with respect to ongoing vehicle automation promise take-over of sub-tasks like keeping speed, distance to a car in front, braking and steering. Other but no less dangerous hazards might develop from such systems, such as unwanted behavioural adaptation, complacency and diverted attention, to name a few. Taking the driver out of the loop is a possible source of losing experience and skill as well. Numerous problems may arise if systems will reach the market without at least some minimal precautions. The HASTE project, commisioned by the European Union aims at the development of methodologies and performance measures to assess the (long term) safety implications of (new) in-vehicle technologies including HMI for road transport.
