Article Synopsis
- The study addresses driver safety in law enforcement by focusing on distractions caused by poorly designed Driver-Vehicle Interfaces (DVIs) in police vehicles equipped with aftermarket gear.* -
- A driving simulation platform was developed to analyze how drivers interact with vehicle controls, using strategically placed sensors on the dashboard and steering wheel to monitor behavior.* -
- A machine learning model was created to assess driver distraction levels, emphasizing the need for further research to ensure that improved DVI designs effectively enhance officer safety during missions.*
Objectives: This study developed multivariate law enforcement officer (LEO) body models for digital simulation of LEO accommodation in police cruiser cabs.
Background: Anthropometrically accurate digital LEO body models, representing the United States LEOs, for computerized LEO cruiser interface simulations are lacking.
Methods: Twenty body dimensions (with and without gear combined) of 756 male and 218 female LEOs were collected through a stratified national survey using a data collection trailer that traveled across the US.
Objectives: This study investigated anthropometric changes of national law enforcement officers (LEOs) in 46 years, compared the differences between LEO data and civilian anthropometry, and identified the magnitude of differences in dimensions measured with gear versus semi-nude measurements.
Background: The best available 46-year-old anthropometric dataset of LEOs has largely become outdated due to demographic changes. Additionally, anthropometric data of female LEOs and LEO measurements with gear are lacking.
The objective of this study was to assess the impact of using alternative mast climbing work platform (MCWP) designs on trunk motion and postural stability with masonry workers while performing bricklaying and stepping down tasks using a conventional MCWP setting (i.e. with a step deck) as well as two types of production tables (straight- and L-shaped).

Thirty-two male participants performed stepping tasks between a ladder top and a roof at simulated elevation in a surround-screen virtual-reality system. The experimental conditions included a "walk-through" and a standard ladder top section supported on flat and sloped roof surfaces.
