“…BAC in g/l is related to BrAC by a ratio of 2:1, in such a way that a BAC of 0.8 g/l (BAC of 0.08%) equals a BrAC of 0.40 mg/l. Driving is a complex task requiring controlled behavior (control over speed, braking, lane position) 8 , 9 , a high level of concentration and attention, a capacity for quick decisions and reactions, high processing capacities through the central nervous system, and good visual processing 10 – 13 . Considering this last point, driving involves the application of different visual functions.…”

In this study, we assessed the influence of moderate alcohol intake on binocular vision, vergence system and simulated driving performance by analyzing the interactions between visual deterioration and driving variables. Thirty young healthy subjects were recruited. For the analysis, we measured: visual function (visual acuity and stereoacuity), phorias and fusional reserves. Also, we checked Sheard’s and Percival’s criteria at near and far. The accommodative convergence/accommodation (AC/A) ratio was calculated and vergence facility was also obtained at near. A driving simulator was used to assess driving performance under natural conditions and after alcohol consumption with a breath alcohol content of 0.40 mg/l. Alcohol intake significantly reduced binocular visual performance and vergence function, except for vertical phorias, horizontal phoria at near and Sheard’s and Percival’s criteria at near. Driving performance parameters also presented a statistically significant deterioration after alcohol consumption. A statistically significant correlation was found between the deterioration in overall visual function and overall driving performance, highlighting the influence of the visual deterioration on the driving performance. Moderate alcohol consumption impairs binocular visual and simulated driving performances, implying a greater safety hazard. In addition, deteriorations in binocular visual function and vergence correlated with simulated driving impairment, which indicates that the deterioration of binocular vision due to alcohol consumption affects driving, thus reducing road safety.

“…Steering errors, defined as lane deviations, were increased both on a driving simulator (Crancer et al, 1969) and in actual driving (Abele, 1958;Allen et al, 1975;Huber, 1955;Sugarman et al,,1973). Mortimer and Sturgis (1979) did not concur, however.…”

“…Velocity maintenance is generally impaired under alcohol (Attwood et al, 1980;Mortimer & Sturgis, 1979;Huntley & Centybear, 1974) and fatigue (Forbes et al, 1958;Platt & Fedderson, 1964Riemersma et al, 1977 but the changes due to fatigue are not consistently found. Lane position also becomes more variable with both alcohol (Allen et al, 1975;Sugarman et al, 1973) and fatigue (Caille & Bassano, 1977;Dureman & Boden, 1972;Mackie & O'Hanlon, 1977;Riemersma et al, 1977;Sussman, & Morris, 1970).…”

“…The noise processes have been characterized as broad band and proportional to the activity in the error signal perceived by the HO, and also proportional to the HO's response (Jex and Magdaleno, 1969;Levison and Kleinman, 1968). Measures of continuous HO behavior have been obtained under normal and impaired conditions (Weir and McRuer, 1973;Allen, Jex, et al, 1975 ;Allen, O'Hanlon, et al, 1979). The HO modeling and analysis portrayed in Figure 1 has more recently been applied to driver longitudinal (speed) control (Allen, Magdaleno, et al, 1997).…”

Summary: This paper reviews past research on stimulus/response analysis methods in continuous control tasks, and describes procedures for specifically measuring driver behavior in a car following task. Example driving simulator data is given for drivers with disease impairments. The data processing methods are summarized and example results are given to demonstrate the data analysis approach. Analysis of driver steering and speed control behavior have been used to identify normal highway operations and effects of various impairments, including drugs, alcohol, fatigue and medical conditions. Typical measures might include characteristics of control (steering, throttle, brake) activity, such as control reversals and expected values such as mean and standard deviation. More powerful time series analysis methods look at the relationship between stimulus and response variables. Fourier analysis procedures have been used to carry out stimulus/response relationships, such as steering response to wind gusts and roadway curvature, and speed response to lead vehicle speed variations. These methods allow the analysis of driver time delay in responding to stimulus inputs, and the correlation of driver response to the stimulus input. Typically, driver impairments lead to responses with increased time delay and decreased correlation.
