Effects of Learning Materials about Automated Driving Level 3 Focusing on Frequency of Driving: Verification by Propensity Score Matching

It is important to consider to teach how to use the new technology safely. Especially, if the users do not learn well, the users will encounter a big trouble. The purpose of this study is to find key points to develop the contents for traffic safety education of level 3 automated driving. The data were 3,240 surveys collected in 2019. The data were learning style, career resilience, and frequency of driving, and the test scores of three types of learning materials. The data were analyzed with logistic regression analysis to calculate propensity score to match high frequency driving group and low frequency group. The study found the difference in learning effect in two groups. The results showed that the personal characteristic factors affecting the high and low driving frequency groups were different. There are more points to consider for the high driving frequency group to provide traffic safety education program.
