The purpose of this study is to analyze the effects of the introduction of the safe rates system in the cargo transportation industry, which has implemented since January 2020 in South Korea and to explore the policy implications for low feeling groups. To this end, factors were classified by domain through factor analysis on the feeling effect of the safe fare system, and cluster types were classified according to effect of each factor through hierarchical clustering and K-means clustering. In addition, to confirm the characteristics of each cluster, ANOVA was performed on demographic characteristics, working conditions, job satisfaction, and system compliance rate and cross-analysis was performed on business types. As a result of the analysis, the feeling effect of the safe rates system was classified into factors for each of four areas: work-life balance, quality of life, safety, and industrial structure. Three clusters were derived from cluster analysis: The first cluster was ‘partially feeling type’, which showed a positive effect only on safety and industrial structure, the second cluster was no feeling type, which showed negative effects in all factors, and the third Cluster is a strong feeling type that showed a positive effect in all factors. These clusters showed significant differences in demographic characteristics, working conditions, job satisfaction, system compliance rate, and business type characteristics. Policy implications include supplementing the announcement of additional provisions of the safe fare system and supporting collective agreement for workers in the BCT long-distance transportation type, which has the highest proportion of no feeling types, activation of Safe rate report center, improvement of sunset restriction for increasing sustainability on safe rates system.
