Research on characteristics of expressway truck accidents in different regions

In order to fully explore differences of truck accident characteristics in different regions and prevent high occurrence of truck accidentsꎬ methods such as taxonomy and social network analysis were applied to study data of major accidents in Zhejiang from South and Jilin Province from North respectively. Thenꎬ based on preliminary classification analysis of dataꎬ a network diagram of influencing factors and a ranking table of centrality were constructedꎬ and two sets of data were compared. The results show that there are great differences in numberꎬ severityꎬ cause and complexity of truck accidents between two provinces. Weather conditionꎬ vehicle type and fatigue driving are important factors that affect accident severity while region differenceꎬ weather and driving experience exert comparatively significant influence on unsafe driving behaviors.
