  • To introduce IHRA-ITS work

  • To explore opportunities to liaise with GRRF in areas of common interest

Intelligent transport systems

Positioning & tracking

Digital maps

Communication links


Image processors

Information databases

Traffic management

Traffic monitoring

Smart cards

Automated aids

Intelligent Transport Systems

Transportation Objectives

  • Reduce congestion

  • Improve safety

  • Increase efficiency

  • Improve comfort

  • Improve transit services

  • Reduce fuel consumption

  • Reduce emissions

Vehicle based driver assistance and crash avoidance systems
Vehicle-Based Driver Assistance and Crash Avoidance Systems

  • Vision enhancement & visual range warning

  • Intelligent speed adaptation

  • Adaptive cruise control

  • Collision warning (e.g., lane departure, rear-end, lane change, intersection)

  • Fatigue/impairment warning

  • Pavement monitoring and friction warning

  • Vehicle Stability Warning and Assistance

  • Emergency reporting and response

  • Backing and merging aids

Levels of automation
Levels of Automation

  • Information

  • Warning

  • Driver assistance (active pedal)

  • Partial control of vehicle functions (steering, stop&go)

  • Complete control of vehicle (AHS)

Rationalizing automation
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
Aspects of System Safety

  • System Reliability

    Reliability of hardware and software, the propensity for malfunction and the potential to go into a dangerous and/or unanticipated safety mode

  • Human Machine Interaction (HMI)

    Key issues are function allocation, driver-vehicle integration and user interface design

  • Overall Traffic System

    The aggregate effect on the traffic system as a whole

Its safety impact framework
ITS: Safety Impact Framework









Direct safety benefits









Direct Safety Benefits

  • Reduction of crash risk through

    • on-board CA systems

    • road-side CA systems

    • tolerance for driver/system errors

  • Mitigation of crash consequences through improved emergency response

Indirect safety benefits









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

Direct safety risks









Direct Safety Risks

  • Driver distraction

  • Driver overload

  • Driver confusion

  • Reduced situation awareness

  • Lack of trust/acceptance due to false or nuisance alarms

  • Increased discomfort, stress

  • Command effect

Indirect safety risks









Indirect Safety Risks

  • Behavioural adaptation

  • Increased travel (pleasurable)

  • Loss of skill & negative transfer

  • Violation of expectation (by non-users)

  • Collision migration (MV to SV, to other users, etc.)

Its safety or is it


Driving Task




ITS Safety, or IS IT?

  • ITS technology is safety neutral - Its implementation is safety critical

  • Safety impact depends largely on the extent to which the system supports users’ needs, and is compatible with human capabilities and limitations

Government s role
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

Enhanced safety of vehicles esv international harmonized research activities

the Netherlands







Enhanced Safety of Vehicles (ESV):International Harmonized Research Activities

  • Australia

  • Canada

  • France

  • Germany

  • Hungary

  • Italy

  • Japan

Esv ihra working groups
ESV: IHRA Working Groups

  • Intelligent Transport Systems

  • Advanced Offset Frontal Crash Protection

  • Pedestrian Safety

  • Biomechanics

  • Vehicle Compatibility

  • Side Impact

Ihra its objectives
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.


  • includes original and aftermarket on-board information, control and communication systems, including

    • driver assistance

    • collision warning and avoidance

    • infotainment

Summary of activities
Summary of Activities

  • Conceptual Framework

  • Workshops

  • Survey of current research

  • Priority Projects

Priority projects
Priority Projects

  • Development of a harmonized safety evaluation methodology framework

  • Driver understanding and expectation of ITS systems

  • Human factors principles checklist

  • Normative data on naturalistic driving behavior

  • Simulator reference test scenarios

  • Improved secondary task methodology for evaluating safety effects of driver workload

  • Harmonization and validation of surrogate safety measures

Importance of its safety research
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

Ihra wp 29 liaison
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

Recommendations vis wp 29
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)
