事故の多い運転者の精神的特質に関する一研究

Abstract

This research has been carried out in order to collect information which would be helpful in the training of truck drivers. The subjects were 50 truck drivers who were high on accident proneness. All subjects had been tested at the trucking company by an examiner trained in psychological testing, and under standardized conditions. The tests used were some of the well known apparatus tests designed to measure basic motor and perceptual capacities and a paper and pencil test for measuring driving aptitude. In addition to these tests, personal data concerning the drivers were available. The high-accident drivers turned out to have many kinds of problems in relation to judgments of speeds and spatial relations, and the division of attention, variability of reaction time, glare sensitivity and so on, together with certain personality traits. Some appropriate counterplots for their retraining should be undertaken immediately for the purpose of preventing traffic accidents.
