In recent years, electric scooters have become one of the emerging modes of short-distance transportation. As the number of people using electric scooters increases, so does the number of their traffic accidents. Therefore, it is extremely important and urgent to pay attention to the safety of electric scooters. In view of the fact that the traditional DBSCAN clustering algorithm needs to determine the Eps and MinPts values by experience, which is not accurate enough, this paper adopts a self-adaptive algorithm to determine the parameters of the DBSCAN algorithm. This algorithm determines the Eps and MinPts values by the distribution of the data itself, so as to improve the accuracy of the algorithm. This paper conducted a case study using data collected from the STATS19 road safety database as an example, and identified six accident blackspots. The clustering results were compared with the MDA-DBSCAN algorithm. The results show that the algorithm has better accuracy and adaptability in black spot identification, and provides more accurate data support and decision basis for urban traffic safety management.
