1 Dr Chris Bearman

2 Investment in Technology New technologies often provide – elegant new solutions to problems – provide new capabilities for the operator

3 Dr Chris Bearman The Benefits of Technology – increasing precision in task performance – reducing operator workload – reducing costs for the organization – reducing operator errors New technology is assumed to be beneficial in

4 Dr Chris Bearman Technology-Related Issues Human Technology Interaction Distraction Failure to Respond to an Alarm Resistance to Technology

5 Dr Chris Bearman Cajon Junction, CA (1996)

6 Dr Chris Bearman Silver Springs, MA (1996)

7 Dr Chris Bearman Chatsworth, CA (2008)

8 Dr Chris Bearman Multiple Warning Alarms Multiple audio and visual alarms may not be easily distinguishable from one another (McLeod et al., 2005). McLeod, Walker & Mills (2005) concludes that Extended AWS has increased the risk of driver unreliability rather than reduce it. Dr Chris Bearman (Univeristy of South Australia) "No-one ever thought that the driver would ignore the warning. It was utterly taken for granted that a driver would always take notice of the signal. (Vaughan, 2000, p.12).

9 Dr Chris Bearman Automatic Cancellation of Warnings 56% of driversautomatically cancelled an AWS warning Drivers response is highly learnt and/or anticipatory in nature. (McLeod et al., 2005)

12 Dr Chris Bearman

13 Topics Key Technology-Related Issues Resistance to Technology Using Mock-Ups Qualitative Research Future Inquiry Workshops Task Analysis Train Simulators Situation Awareness

14 Dr Chris Bearman Multiple Warning Alarms Multiple audio and visual alarms may not be easily distinguishable from one another (McLeod et al., 2005). McLeod, Walker & Mills (2005) concludes that Extended AWS has increased the risk of driver unreliability rather than reduce it. Dr Chris Bearman (Univeristy of South Australia) Technology provides great opportunities… …But it also can introduce vulnerabilities into the safety system …and it may not always be accepted by the operators.

15 Dr Chris Bearman The Keys to Maximising Investment in New Technology Understand how people will use the technology Assess how the job will change with new technology Design the technology around the person Get early user input Anticipate resistance and plan how to deal with it
