Vehicles on Australian and New Zealand roads carried factory-fitted PAEB. Pedestrian detection made the difference: AEB without it showed no reduction in these collisions.

Relation to AI

The study compares PAEB-equipped vehicles with vehicles that have no AEB and with vehicles that have AEB without pedestrian detection, so it isolates the pedestrian detection; the comparison is observational.

Additional value from AI

No reduction for AEB without pedestrian detection, so the gain is tied to the detection. [1]

Benefit marks

Depth

The number and color show the depth of a benefit.

  1. Depth 1. A convenience, or time or money saved.
  2. Depth 2. A measurable improvement in a result or ability.
  3. Depth 3. A lasting change, an ability restored, or a risk removed.
  4. Depth 4. A serious harm averted or a serious condition resolved in time.
  5. Depth 5. A life or livelihood preserved, or a change documented across a population.

Beneficiary

  • Circle: a person
  • Square: an organization
  • Triangle: society

Evidence

  • Solid. A court or regulator found a benefit, or researchers independently studied it.

  • Hatched. Independent reporting.

  • Outline. Claimed by the parties. Only the people or organizations involved, or sources whose independence has not been assessed, support the benefit.

The fill changes with the evidence. The depth color stays the same.
