Intelligent Automobiles

In-Vehicle Information Systems (IVIS) - compete with driving task:

• telecommunications and infotainment systems (e.g., e-mail, Internet access), navigation systems

Advanced Driver Assistance Systems (ADAS)- support driving task:

• collision warning systems, adaptive cruise control, lane departure warning, lane change aids, and parking aids.


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

Encourage technologies that are likely to have safety benefits

Discourage technologies that are likely to have an adverse effect on safety

Driver Distractions

Visual (eyes off road)Manual (hands off wheel)Cognitive (mind off

driving)Auditory (sounds)


Sources of Distraction

Wireless communication (cell phones) Navigation system destination entry Map and other complex visual displays In-vehicle office tasks (e-mail, PDA, Internet) Infotainment (location-based services, DVD) Warnings from driver assistance systems Multifunction displays and controls


Levels of Driver Assistance

InformationWarningActive controls (e.g., gas pedal)Partial control of vehicle functions

(steering, stop&go)Complete control of vehicle

Driver distractionDriver overloadDriver confusionFalse or nuisance alarmsCommand effect


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 to the driving task


Indirect Safety Risks

Behavioural adaptationIncreased exposureLoss of skill & negative transferViolation of expectation (by non-users)Collision migration (MV to SV, to other

users, etc.)

Key Challenges for Government

Traditional policy paradigms not suitable:• Design cycle shorter than policy cycle• Technology is diversifying rapidly• Behavioural science lags technology

Integration by consumer, not industryJurisdictional boundaries no longer valid


Need for New Paradigm

Driver-system integration must be an integral part of motor transport system development.This has implications for: • System design• Regulatory policy

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.


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.


Summary of Activities

Conceptual FrameworkWorkshopsSurvey of current researchPriority Projects


IHRA ITS Priority Projects

1. Development of a harmonized safety evaluation methodology framework

2. Driver understanding and expectation of ITS systems3. Human factors principles checklist4. Normative data on naturalistic driving behavior5. Simulator reference test scenarios6. Improved secondary task methodology for evaluating

safety effects of driver workload7. Harmonization and validation of surrogate safety

measures


Importance of ITS Safety Research

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 research focus• Summarize state of knowledge

• Coordinate joint research

• Develop test procedures

WP.29 regulatory focus• Identify regulatory needs and priorities.

IHRA could coordinate the regulatory development research needed to support WP.29 work program
