Driver distraction due to non-driving-related tasks (NDRT) is among the leading causes of road traffic accidents. Such activities are typically the result of a deliberate decision by the driver and divert attention from the primary driving task. In the context of (partially) automated driving systems, the risk increases that drivers will more frequently engage in NDRTs and become distracted. This effect is further amplified by the growing use of mobile devices. Studies show that as system reliability increases, driver attention tends to decrease while engagement in NDRT rises. With the introduction of SAE Level 3 systems in Switzerland planned for 2025, this issue is gaining further relevance.
The aim of the project is to systematically assess distraction caused by NDRT and to develop measures that prevent or at least hinder such behavior, depending on the driving context. The focus is particularly on technical in-vehicle solutions (e.g., HMI design) as well as external interventions. The project investigates in which situations NDRT may be permissible without compromising road safety especially in vehicles equipped with automated driving systems that temporarily assume specific driving tasks. The project contributes to the development of effective and feasible measures, supports the design of safe driver assistance systems, and provides evidence-based recommendations for legislation and monitoring strategies to reduce distraction-related risks in road traffic.
