ASTiD

Advisory System for Tired Drivers

ASTiD® is a predictive, unobtrusive, early warning algorithm that empowers drivers to self-monitor and self-manage their own risk of driver fatigue.

ASTiD® is built in layers comprised within two distinct but cross-correlating systems that monitor the known variables which are indicative and typify tired driving.

Using complex signal processing, the first system (i) is “knowledge-based” and provides an electronic template predicting hour by hour the likelihood of a driver falling asleep over a 24hour period. It is influenced by a prior sleep model and a real-time fit-for-duty assessment (Fatigue RADAR app)

The second (ii) is a “dynamic steering-based” system that monitors driving deterioration over time. Information from (i) is fed into (ii) and this continuous cross-referencing, outputs a fatigue risk index every minute that can be plotted to present a visual indication of the drive.

Simply put, one system predicts fatigue whilst the other indicates when it’s happening.

The ASTiD hardware is accessed via a Bluetooth enabled, mobile app. Once the driver has logged in, the app then transmits the fatigue-risk data to the cloud-based fatigue dashboard whilst simultaneously providing real-time, in-vehicle feedback to the driver of their increasing risk to fatigue.
