Title of product being suggested:
A Guide to Human Factors Integration in Engineering Design
Date of suggestion:

Reason for suggestion:
This guideline would complement the RISSB standard ‘AS 7470 Human Factors Integration in Engineering Design’ successfully published in 2016.
Sponsored by RISSB Standing Committee:
Safety Standing Committee
Scope:
Scope of the project
The scope of the project would be to produce a national guideline in accordance with RISSB’s accredited development process.
Scope of the guideline
In 2014, TfNSW published a human factors integration standard and an accompanying human factors integration guidance document. An industry project was initiated to convert the existing TfNSW standard into a RISSB standard under the RISSB Manager Safety, Systems and Innovation. In November 2016, the revised standard was published by RISSB as ‘AS 7470 Human Factors Integration in Engineering Design ‘.
Feedback on AS 7470 is very positive and the provision of the guidance document would add further value, as well as encouraging and enhancing the uptake of AS 7470.
The production of this guideline would adopt the same process for the revision and publication of the existing TfNSW guidance document as a RISSB guideline. It is proposed to use the same basic method of development and utilise the same members of the Development Group as for the previous project. As for the previous project the ASA Manager Human Factors would take the lead technical development role.
For these reasons, it is expected that the development cost/effort will be minimal. Only a small amount of new work will be required to account for the inclusion of new topics in the RISSB document that were not originally in the TfNSW document. Thus, the project is regarded as high value, low cost.
Hazard identification:
1
Harm to environment
2
Harm to rolling stock processes
3
Collision/SPAD/Alerting System Failure/Poor cab vision/
4
Driver fatigue/overspeed/ brake applied too late
5
Inadequate vehicle access
6
Signals failure/train authority system failure/control system failure

Benefits:

Safety risk
Poor consideration of human factors can be a significant factor in the frequency of errors which of course can lead to safety and other types of incidents.
The document gives guidance on the implementation of the human factors standard and therefore should lead to a general improvement in the consideration of projects across a range of rail domains.
Interoperability / harmonisation
Adoption of the guidance document would lead to a consistent way of thinking about HF integration across the industry. This is turn will lead to the recognition of the benefits of interoperability and harmonisation of standards for critical human factors interfaces
Financial
One of the key elements of the combined standard and guidance document is to enhance the benefit of the consideration of human factors during design for improving efficiency and effectiveness of operations as well as safety. Improved guidance in this area will improve the future quality of rolling stock and or equipment used on the network.
