Open data on road traffic accidents accumulation, processing and analysis

Introduction. An urgent task for any municipality is the development of an Integrated Traffic Management Scheme, which is based on an analysis of the current situation. At the same time, the most important element is the analysis of road traffic accidents (RTA). The purpose of this study is to develop a methodology for accumulating, processing and analyzing the data on road accidents from the main official source - the State Inspectorate for Road Safety (GIBDD). Description of the problem. The data can be uploaded from the traffic police portal in two formats, but none of them allows for automated analysis of road accidents and presentation of its results using geographic information systems (GIS). Proposed methodology. The paper proposes a methodology for analyzing traffic accidents, including the following steps: uploading data from the site, converting data into convenient formats, entering data into a geographic information system, analyzing data using geographic information systems. Methodology approbation. Using the proposed methodology, an analysis of traffic accidents in the Cheboksary agglomeration was made and its visualization was made using GIS. Conclusions. The use of information about road accidents in the formats offered on the traffic police website is impossible either for analysis or for visualization in a GIS. The proposed method for accumulating, processing and analyzing accidents based on data from an official source using GIS makes it possible to automate the process and improve the quality of accident analysis.
