Rationalizing Automation
Each level has unique safety issues
Each level must coexist with other levels
Progression from one level to next is not incremental– it represents a radical change in driving task

Aspects of System Safety
1. System ReliabilityReliability 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, driver-vehicle integration and user interface design
3. Overall Traffic System The aggregate effect on the traffic system as a whole

Indirect Safety Benefits
Reduced exposure (optimized routes and trip lengths, and greater choice of mode)
Reduced exposure to unauthorized use (elicense)
Reduced traffic variance and conflicts (through better traffic management and improved interaction between driver and other road users)
Reduced driver stress and fatigue

Discourage technologies/implementations that are likely to have an adverse effect on safety
Encourage implementation of technologies that are likely to have safety benefits

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.

Importance of ITS Safety Research
Expands ESV’s role into crash avoidanceElaborates the role of governments with
respect to ITS safetyITS safety is currently unregulated;
therefore, there is a reasonable prospect for harmonized policies based on shared scientific understanding of the issues

Recommendations vis WP.29
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
Coordinate with WP.1 and WP.15 on ITS-related matters (ISA)
