An Assessment of the Roadway segment Environmental Influence on Traffic Crash
- 1 Olabisi Onabanjo University, Ago-Iwoye, Nigeria
Traffic crashes remain a critical global issue. Governments have introduced measures such as legislation, driver education, and improved road design to address this challenge. This study examines highway traffic collision data from Federal Road Safety Corps (FRSC) records (2020–2022), integrating georeferenced maps, road networks, satellite imagery (Landsat, Google Maps), Shuttle Radar Topography Mission (SRTM) data, and field survey data from blackspot road segments. Analysis, which was done in ARCgis 10.8 environment, identifies 66 blackspots across 18 federal routes, with 56 curved sections linked to these routes. The findings reveal a strong correlation between environmental terrain and crash occurrences. The study advocates for the strategic placement of road signs and symbols and highlights the necessity of leveraging Global Positioning System (GPS) and Geographic Information System (GIS) technologies for accurate traffic data collection and analysis, particularly in complex terrains. These recommendations aim to enhance roadway safety and inform evidence-based policymaking.
