Ergonomics Division, Transport Canada World Forum for Harminization of Vehicle Regulations WP.29 Geveva November 2001 Aspects of System Safety 1. System Reliability • IHRA-ITS Reliability of hardware and software, the propensity for malfunction and the potential to go into a dangerous and/or unanticipated safety mode. 2. Human Machine Interaction (HMI) • Key issues are function allocation, the design of interface, definition of dialogue between the user and the system. 3. Overall Traffic System • The aggregate effect on the traffic system as a whole. Ergonomics Division, Transport Canada World Forum for Harminization of Vehicle Regulations WP.29 Geveva November 2001 Scope includes original and aftermarket on- board information, control and communication systems, including IHRA-ITS • telematics • driver assistance systems, and • collision warning and avoidance systems Ergonomics Division, Transport Canada World Forum for Harminization of Vehicle Regulations WP.29 Geveva November 2001 Summary of Activities Conceptual Framework Workshops IHRA-ITS Survey of current research Priority Projects For further information visit http://199.79.179.92/ITS/ITS.html Ergonomics Division, Transport Canada World Forum for Harminization of Vehicle Regulations WP.29 Geveva November 2001 Priority Projects 1.
