Ergonomics Division, Transport Canada World Forum for Harminization of Vehicle Regulations WP.29 Geveva November 2001 IHRA-ITS n Safety impact depends largely on the extent to which the system supports users’ needs, and is compatible with human capabilities and limitations Driving Task ITS Collisions n ITS technology is safety neutral - Its implementation is safety critical ITS Safety, or IS IT?

Ergonomics Division, Transport Canada World Forum for Harminization of Vehicle Regulations WP.29 Geveva November 2001 IHRA-ITS Government’s Role  Discourage technologies/implementations that are likely to have an adverse effect on safety  Encourage implementation of technologies that are likely to have safety benefits

Ergonomics Division, Transport Canada World Forum for Harminization of Vehicle Regulations WP.29 Geveva November 2001 IHRA-ITS ESV: IHRA Working Groups  Intelligent Transport Systems  Advanced Offset Frontal Crash Protection  Pedestrian Safety  Biomechanics  Vehicle Compatibility  Side Impact

Ergonomics Division, Transport Canada World Forum for Harminization of Vehicle Regulations WP.29 Geveva November 2001 IHRA-ITS IHRA-ITS : Objectives  to coordinate international policy-oriented research to minimize the potential adverse consequences of on-board ITS technologies.  to develop procedures for the evaluation of safety of in-vehicle information, control and communication systems.  to provide an international view of the state of research into understanding the safety impact of driver workload and distraction.

Ergonomics Division, Transport Canada World Forum for Harminization of Vehicle Regulations WP.29 Geveva November 2001 IHRA-ITS Aspects of System Safety 1. System Reliability 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 IHRA-ITS Scope  includes original and aftermarket on- board information, control and communication systems, including 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 IHRA-ITS Summary of Activities  Conceptual Framework  Workshops  Survey of current research  Priority Projects For further information visit

Ergonomics Division, Transport Canada World Forum for Harminization of Vehicle Regulations WP.29 Geveva November 2001 IHRA-ITS Priority Projects 1. Development of a harmonized safety evaluation methodology framework 2. Driver understanding and expectation of ITS systems 3. Human factors principles checklist 4. Normative data on naturalistic driving behavior 5. Simulator reference test scenarios 6. Improved secondary task methodology for evaluating safety effects of driver workload 7. Harmonization and validation of surrogate safety measures

Ergonomics Division, Transport Canada World Forum for Harminization of Vehicle Regulations WP.29 Geveva November 2001 IHRA-ITS Importance of ITS Safety Research  Expands ESV’s role into crash avoidance  Elaborates the role of governments with respect to ITS safety  ITS safety is currently unregulated; therefore, there is a reasonable prospect for harmonized policies based on shared scientific understanding of the issues

Ergonomics Division, Transport Canada World Forum for Harminization of Vehicle Regulations WP.29 Geveva November 2001 IHRA-ITS Key Challenges for Government  Traditional policy paradigms not suitable: Design cycle shorter than policy cycle Technology is diversifying rapidly Science lags technology  Integration by consumer, not industry  Jurisdictional boundaries no longer valid

Ergonomics Division, Transport Canada World Forum for Harminization of Vehicle Regulations WP.29 Geveva November 2001 IHRA-ITS IHRA-WP.29 Liaison  IHRA research focus Summarize state of knowledge Coordinate joint research Develop test procedures  WP.29 to identify regulatory needs and priorities. IHRA to coordinate the regulatory development research to support WP.29 work program

Ergonomics Division, Transport Canada World Forum for Harminization of Vehicle Regulations WP.29 Geveva November 2001 IHRA-ITS Recommendations vis WP.29  coordinate with WP.1 and WP.15 on ITS-related matters (ISA)  Develop strategy for global regulation development for on-board ITS ST – coordinate among existing GR’s, lead? LT – create new GR  utilize IHRA-ITS WG as Informal Group for ITS-related matters
