The over-representation of intoxicated pedestrians in serious injury and fatal crashes compared to non-intoxicated pedestrians may be due, in part, to the effects of alcohol on the ability to select gaps in the traffic for safe road-crossing. An experiment is described that tests the effectiveness of an experimental approach to elicit road-crossing responses among groups of intoxicated (BAC=between 0.05% and 0.10%, mean=0.07%) and sober adults (BAC=0.00%). Some subtle effects of alcohol on road-crossing decisions were found, particularly at higher BAC levels of 0.07–0.10%. Highly intoxicated participants showed some lack of awareness of impairment, a tendency to engage in risky road-crossings, and difficulty integrating speed and distance information in a timely manner, necessary to select safe gaps in the traffic. These results are discussed in terms of the effect of alcohol impairment on perceptual and …
