About
Fifty notes on driver behaviour monitoring, written from the operator's side and taking the driver's view as a design input.
Who this is for
Whoever has been asked to deploy one of these and needs to know what it will actually detect. Whoever will review the clips and hold the conversations, which is the job nobody budgets. And the drivers, whose cooperation determines whether the data describes anything.
How the notes are written
The statistics stated plainly. Regression to the mean means a coaching programme applied to the worst performers will appear to work whether or not it does. Knowing requires a comparison group, which almost nobody uses.
The uncomfortable findings included. The route dominates the score. An emergency braking intervention registers as harsh braking by the driver. A hard brake that avoided a collision is good driving that scored badly. And the strongest safety measures are not behavioural.
Limits stated. Three notes are entirely about what the data cannot tell you, what monitoring cannot fix, and what this subject is not.
What is deliberately absent
How to enable live cab viewing quietly. How to present a proprietary score as validated. How to use safety data for timekeeping or break monitoring.
These appear only in the notes explaining why they should not be done, and requests to help with them are declined in the same terms.
No effectiveness figures
No percentages are quoted, deliberately. The published figures in this field are almost all before-and-after comparisons without control groups, and repeating them would repeat the error the notes describe.
About the pictures
The patterns on section pages are generated from the section name by a small program: a line with scatter around it. They are ornament and nothing more — they depict nothing, illustrate nothing, and carry no information. They exist because pages with no image at all look bare.
About this domain
This address previously hosted a university research project's website, written by named academics and containing personal accounts given to them in confidence.
None of that material is here. It belongs to its authors and to the institution that supported it, and reproducing it on a domain that changed hands would have created something that looked like a citable source and was not.
