One of the representative road safety measures in Japan is traffic enforcement, and to implement in accordance with the actual condition, traffic execution plans have been formulated at each police station since 2011. These plans are conducted in the PDCA cycle, and the actual traffic enforcement is carried out based on the plans. However, there have been no studies which grasp the actual condition and compare regions of these Plans. Therefore, this study attempts to quantitatively organize the components and characteristic of the traffic execution plans of 5 stations in Hokkaido by using text analysis. As a result, the traffic execution plans were able to be classified into 11 constituents, and it was found that the effect of suppressing traffic accidents is expected also for countermeasures not focusing on traffic violation arrest. Also, co-occurrence relation and implementation focus in the plans, there were both similarities and differences between each police stations, and regional characteristics and road environment were cited as a factor.
