Attention to Human Error
• National Rail Safety Action Plan–Fatigue Risk Management Program–Close Calls Reporting System
But . . .
Not Addressing “Design Induced Error” in a Meaningful Way — Until Now.
33
“Design-Induced Errors”
• Human Errors that Occur as a Result of Interacting with Systems that Were Designed with Little Consideration for Human Abilities and Limitations.
• Errors Produced as a Result of Lack of Utilization of Error Reducing Design Approaches (i.e. Redundancy, Feedback, Intuitiveness, Easy Recovery From Input Errors, etc.)
44
Introducing Technology Safely
• Safe Introduction of New Railroad Technologies
• Upgrade of Existing Technologies Without Compromising Safety
• Efficient Use of Technology (Promotes Rail Commerce)
55
There is No Such Thing as an Unmanned System
66
Technology Process
• Lack of Standardization in How Technology is Introduced in the Railroad Industry.
• Is There a Method or Process to Examine Possible Risks and Limitations of the Technology?
• Product Safety Plan?
How we introduce technology can directlyHow we introduce technology can directly affect human error and safety.affect human error and safety.

What is HSI?
• interdisciplinary • technical and management processes • integrating human considerations • essential enabler
"Human Systems Integration: interdisciplinary technical and management processes for integrating human considerations within and across all system elements; an essential enabler to systems engineering practice.”

What You Don’t See…
You Don’t See the Hidden Costs Related to Training, Manpower, or Error-Inducing Designs. Human Factors are Part of the System.
Poor Integration of Humans Into Advanced Technology is Costly.

Why the Interest/Expectations
• Disciplined, Unified, and Interactive Approach
• Incorporate Human Considerations into System Design
• Domains are Interdependent and Addressed Together
• Improve Total System Performance Not Just One Piece
• Improve Operational Effectiveness and Suitability
• Reduce Total Cost of Ownership
• Incorporate Processes and Structures to Improve Performance by Improving Performance of all the Parts of the System
1414
• Simulation and Modeling Help Derive Human and System Requirements
• Use Lab Tools Across HSI Elements for integrated solution
• Simulation and Modeling Help Derive Human and System Requirements

HSI Returns
• Leverages Research and Analysis to Optimize Investment Decision-Making to Yield Greater Return on Investment
• Direct testing of requirements, design, and implementation
• Improved Safety• Better Performance• Manpower Cost savings
1919
HSI Way Ahead• National Rail Safety Plan increasing safety and
efficiency across the System
• HSI in Product Safety Plans
• Improved Manning of New and Existing Train Systems
• HSI Brings the Human Factors/Element into the Mix for Rulemaking, Systems Operation, and Operational Work
• Addresses Human Element in PTC, RCL, Close Call Reporting Systems (CCRS)
