Fatigue
Strongly associated with collisions, barely addressed by scoring, and mostly created by decisions taken before anyone got in a vehicle.
Analysis
Where the risk is
The strongest contributors are schedule, vehicle and exposure. Most of them are decided before anyone gets into a vehicle.
6 notes
Distraction
Phones are the headline and the work-supplied devices are the harder problem, because the organisation put them there.
Analysis
Speed
The best-evidenced link to collision risk, the easiest thing to measure badly, and the one where the schedule usually decides the outcome.
Analysis
Driver Assistance Systems
The vehicle intervenes at the moment of risk, which is weeks earlier than any coaching programme. How the two interact, and badly.
Analysis
New Drivers and Agency Drivers
The highest-risk period in any driver's tenure, addressed by induction rather than by monitoring, and the agency case that is worse.
Analysis
Vulnerable Road Users
The collisions with the worst outcomes involve people outside the vehicle, and the measures that address them are mostly not behavioural.
