Combined Dataset of Road Accidents, AADT, and Spatial Attributes for the D1 motorway (Czech Republic, 2025)

Description

This dataset contains a processed and integrated subset of multiple data sources. Due to licensing and data access restrictions, the original raw datasets (police-reported accidents, full road network data, and full traffic census data) are not publicly redistributed. The provided dataset includes only derived and combined data necessary to reproduce the analyses presented in this study. The dataset is structured as a series of linear segments with a fixed length of approximately 10 meters along the D1 motorway. Each segment represents a spatial analysis unit to which road accidents, traffic intensity (Average Annual Daily Traffic, AADT), and geometric road attributes are assigned. This segmentation enables high-resolution spatial analysis of accident occurrence and its relationship with traffic flow and road characteristics. The dataset is divided into four files representing directional segments of the motorway: (1) Prague–Říkovice, (2) Říkovice–Prague, (3) Czech/Polish border–Přerov, and (4) Přerov–Czech/Polish border. Each file contains integrated information on road accidents, traffic intensity (AADT), and spatial road attributes for the corresponding motorway segment and direction. The dataset is intended for research in transport safety, traffic engineering, and spatial data analysis, and supports reproducible analysis of relationships between road geometry, traffic intensity, and accident occurrence.
