Purpose

• Human error is a major source of safety risk
• YB3 made only a few references to human error /
  human factors
• Need for practical advice to designers of
  railway systems which involve human interactions
• Advice would be useful to other people e.g.
  independent safety assessors and safety
  regulators
• Need for a human error application note
