TECHNICAL CHALLENGESPromise of Advanced In-vehicle Alcohol Detection Technologies


11

ReliabilityDefinition

The probability for any given design or process to execute within the anticipated operational or design margin for a specified period of time and under expected operating conditions with a minimum amount of stoppage due to a design or to process errors, when working under normal operations through the assumed design life of a product or service.

Reliability6-Sigma vs. 3-Sigma

Level Yield PPM Potential mis-BAC Readings

3-Sigma 99.73% 2,700 961,200,000

6-Sigma 99.9997% 3.4 1,068,000


13

356 Billion trips annually by personal vehicle Assumes only one BAC test per trip False positives, false negatives, failure to read


14

Reliability3-Sigma (2,700 PPM) vs. 6-Sigma (3.4 PPM)

3-Sigma case greatly exceeds estimated number of drunk driving trips occurring annually

961,200,000 mis-readings >> 159,000,000 DWI Trips 2.7 million potential mis-classifications per day

6-Sigma case still risks considerable consumer backlash 3,740 potential mis-classifications per day Almost 150 potential mis-classifications every hour


15

Operational or Design MarginImpairment vs. “Bright Line” BAC Legal Limit

0.15%: Substantial impairment, vomiting, major loss of balance

0.10%: Slurred speech, poor coordination, slowed thinking

0.08%: Judgment, self-control, reasoning, memory impaired

0.05%: Exaggerated behavior, lowered alertness, release of inhibition

0.02%: Some judgment loss, slight body warmth, altered mood

Alcohol Ignition InterlocksAlcohol Consumption in the U.S. According to the CDC:

37.5% of persons 18 years of age and older are considered a “lifetime abstainer” or a “former drinker”

62.5% are considered a “current drinker” Alcohol consumption among “current drinkers” is

classified as follows: 68.8% “light” – 3 drinks or fewer per week 23.4% “moderate” – more than 3 drinks and up

to 14 drinks per week 7.9% “heavier” – more than 14 drinks per week


20

Alcohol Ignition Interlocks1970s Safety Belt Interlock Experience

Percentage of “lifetime abstainers”, “former drinkers” and “light drinkers” is similar to the percentage of safety belt nonusers in the 1970s

While safety belt usage has risen to historically high levels

Alcohol Ignition Interlocks1970s Safety Belt Interlock Experience

Consumer resistance to interlocks remains high Generally, the higher the

effectiveness rating for a device, the lower the acceptability rating

Consumers may consider interlocks to be excessive in their attempt to control driver behavior and limit freedom of choice

CONCLUSIONSPromise of Advanced In-vehicle Alcohol Detection Technologies


29

Conclusions No silver bullets – suite of countermeasures

needed to eliminate drunk driving Emerging technologies suggest that the

possibility of eliminating drunk driving is real Substantial research and development is

needed to confirm this possibility Need to expand application of current

technology interlocks
