OUTLINE Goal

Motivation Objective Methodologies Visual Acuity, Vision ESRA DAT™ and ESRA DVAT™ Driving simulators Relative Accident Involvement Ratio Bathtub curves Recommendations Conclusions

To develop an efficient balance between safety and security to ensure the utmost quality of our nation’s transportation infrastructure.

•Inadequate and inaccurate current license testing technologies.

•No comprehensive license testing methods exist in other transport sectors.

MOTIVATION

Promote safety through:

• automated testing.

• improved vision screening techniques.

OBJECTIVES

1. Collect and analyze collision data.

2. Survey all motor vehicle directors.

3. Present design of an experimental automated test system.

4. Highlight the significance of vision screening measures other than standard visual acuity.

METHODOLOGIES

None of the vision testing equipment

currently in use:

• screen licensees for vision and cognition problems.

• promote road safety. • reduce collisions, injuries,

and fatalities.

CURRENT STATE OF THE ART

•a measure of the ability to visually distinguish fine details.

•accounts for less than 0.1%of the visual field (Fink and Sadun, 2003).

VISUAL ACUITY

•Vision measures other than standard acuity needed for assessing at-risk drivers.

•Our systems promote older drivers to safely operate motor vehicles longer.

What do these diseases now have in common?

No license test screening component for Glaucoma or Age-Relate Macular Degeneration (AMD), two of the fastest growing diseases that can result in vision loss.

• antiquated 1937 visual standards.• 1925 report approved by the

American Medical Association.• widespread implementations and

modifications of the Snellen Eye Chart of the 1860s.

Current MVD Vision Standards:

HEALTH INSURANCE STATUS

•More than 80 million Americans lacked health insurance (American Public Health Association, 2002- 2003).

Disease Control.

HEALTH INSURANCE STATUS

• In the USA, it is illegal to operate a vehicle without a license and insurance.

• It is not illegal to lack health insurance.

We call for a radical departure from the traditional and inadequate testing currently in place.

TEST RECOMMENDATION

•Bye-bye, long lines. Hello, ESRA. ™

We proudly introduce the

ESRA Dynamic

Vision Assessment for Transportation™

Automated vision function test

Automated vision condition test

Driving simulator vision status test

Computer network to allow for complete computer automation features, tests, score reports, records, and databases

We also proudly introduce

ESRA Dynamic

Assessment for Transportation™

DAT™

ESRA Dynamic Assessment for Transportation™ (ESRA DVAT™)

Vision attention/ cognition test

Knowledge, safety, laws, and identification test

Operation skills test

Computer network to allow for complete computer automation features, tests, score reports, records, and databases

•May be beneficial to novice licensees.

•May be useful for screening at-risk licensees and others with dementia, especially Alzheimer’s Disease.

ESRA DAT™ DRIVING

SIMULATORS*

Safety studies and potential liability issues need to be addressed for all driving simulator usage as discussed in “New, Improved, Comprehensive, and Automated Driver’s License Test and Vision Screening System” by Sandy H. Straus.

ESRA DAT ™ DRIVING SIMULATORS FEATURES

–weather and light conditions.

–Self-customization driving scenarios.

–simulated visibility and contrast reduction due to

fog, rain, and snow.

ESRA DVAT™ and DAT™

•cost-effective.•objective.•environmentally

friendly. • long line reductions.

We used RAIR to quantify millions of collisions among Arizona and Florida drivers of all ages through databases of two-vehicle accidents.

RELATIVE ACCIDENTINVOLVEMENT RATIO

(D1 i,j /ΣΣD1 i,j )

RAIR i,j = ___________

(D2 i,j /ΣΣD2 i,j )Where: i = type of drivers; j = type of conditionsD1 i,j = number of at-fault drivers of driver type i for type j conditions.

D2 i,j = number of not-at-fault drivers

of driver type i for type j conditions.

RAIR CALCULATION

•RAIR Age 80 to 89 years most likely at-fault in collisions compared to all other age cohorts.

•RAIR Ages 50 to 59 years most likely at-fault in environmental factors and manner of collisions.

RAIR CONCLUSIONS

These results are consistent among drivers cited for collision involvement due to visual defects.

RAIR VISUAL DEFECT

CONCLUSIONS

Drivers ages 80 to 89 years are about twice as likely to be at-fault when compared to the cohorts ages 16 to 19 years in several categories of collisions.

RAIR OLDER DRIVER

CONCLUSIONS

We find that many of our results follow reliability engineering principles based on bathtub curves.

DEFINITIONS

Develop a new vision standard for driver’s license issuance and renewal.

VISION STANDARD RECOMMENDATION

Ensure that the ESRA DAT™ or ESRA DVAT™ system provides:

• instant scoring. •short and effective on-site

testing. •score reports linked by

network.•bilingual capabilities.

RECOMMENDATION

ADDITIONAL FEATURES RECOMMENDATION

The ESRA DVAT™, and ESRA DAT™ can incorporate other features:

• biometrics, • automated written tests, • and/ or cognition skills tests.

MEDICAL RECOMMENDATION

• Combine forces with medical agencies and officials, as well as other transport licensing bureaus, on developing a method of assessing scores submitted through the ESRA DAT™ and ESRA DVAT™ Systems.

Shorten the periods between driver’s license issuance and renewal for vision testing, in particular for:

LICENSE TESTING RECOMMENDATION

•Drivers age 15-19 years (every two years).•Drivers age 50-70 years (every two years).•Drivers age 70 years and

over (every one year).•All other drivers (every four

years).

TESTING RECOMMENDATIONS

We call for new and uniform federal visual standards and vision tests in all the United States.

VISUAL STANDARD RECOMMENDATION

A completely automated system can be used to identify all licensees, irrespective of their residency. This would simplify the licensure process and paperwork.

AUTOMATED SYSTEM RECOMMENDATION

FEDERAL VISUAL STANDARD

RECOMMENDATION

Federal visual standards would also eliminate those who may not visually or cognitively qualify for a license in one state from obtaining a license in another state.

•Federal visual standards support similar recommendations as these relate to driver's licenses and other documents introduced through the 9/11 Commission and by the McCain-Lieberman bill introduced in the U.S. Senate, The Intelligence Reform Bill, and H.R. 418.

FEDERAL VISUAL STANDARD RECOMMENDATION

•New vision screening methodologies and standards are now needed to:•promote safety, •predict visual impairment, and •evaluate possible restriction or confiscation of transportation licenses.

CONCLUSIONS

•Self-assessment tools, education courses, and, e.g., driving skill programs can only complement the new ESRA transportation license test designs and reforms.

CONCLUSIONS

•Safe, improved, and comprehensive testing is now needed.

•ESRA automated systems and methodologies will ultimately benefit all sectors of transportation.

TESTING CONCLUSIONS

These ESRA systems and procedures may also reduce the incidence of fraud as these relate to license issuances such as hazardous materials transport.

HAZMAT CONCLUSION

•The ESRA DAT™ may be the first of its kind in any transportation agency in the world to implement the most sophisticated technology available.

ESRA DAT™ CONCLUSIONS

•New policies are now needed at the federal and state levels to immediately implement transportation license test designs and reforms as envisaged by ESRA.
