The research considered the various developments on braking systems, and the ability of the technology in the vehicle to control braking.


The team of researchers considered many systems and reviewed accident data and modelled the impacts of reduced congestion and injury/fatality costs by accident reduction. A cost benefit analysis was conducted.

Key Findings:

  • At the time of publishing three lorry manufacturers were offering AEB systems and the study found there was a better cost benefit ratio for the use of this type of system on HGVs than cars due to greater impacts should an accident occur.

This document found that Autonomous Emergency Braking systems do have a positive effect and should be further developed and implemented.
