Unavailing Roadway Environmental Characteristics that influences Road Traffic Crash occurrences and Fatality in Oyo State Nigeria

This study sought to ascertain the effect of environmental highway elements on traffic crashes. Using statistics on traffic accidents from the Federal Road Safety Corps (FRSC) for the years 2020–2022, a study was carried out in the Nigerian state of Oyo. Blackspots along different routes were discovered from the record, along with the kind of collision and environmental conditions on the roadway. Environment factors like the accident site, weather, highway flaws and geometry, and road surface condition contributed to blackspots. 9886 traffic crashes were included in the analysis. Compared to 3.19% and 3.57% at dawn and sunset, respectively, the proportion of traffic crashes resulting in injuries was 12.60% and 12.97%. When it comes to road traffic collision occurrences, crash scene light and roadway segment geometry have a stronger significant link than road surface quality, which has a very weak significant relationship with road hazardous environmentalelements. The degree of light at the collision site, which is symbolised by sunrise and sunset, exacerbates the severity. misty, foggy, stormy, or wet, four-way intersections, limited or single lanes, flat or straight roads, lack of a conventional road guard, and insufficient road shoulder Pot holes and dry or wet patches on the road have p values that are less than the alpha set value of 0.005, making them statistically significant factors in fatality and injury crashes.
