Details

The Department for Transport commissioned TRL to investigate the accident risk posed by E/HE vehicles and compare it with that for equivalent vehicles with traditional internal combustion engines (ICEs), to determine whether E/HE vehicles are audibly more difficult to detect.

This report presents the findings from the study, based upon

  • a review of vehicle accident statistics
  • a programme of practical measurements to compare the noise of E/HE and ICE vehicles
  • a small-scale subjective assessment of the noise from these vehicles involving vision-impaired participants
