“…In a collision at an intersection, one vehicle is likely to stop or move at a lower speed, whereas, on a single road, both vehicles may be moving at high speeds. Interestingly, this result is consistent with the findings of a study on pedestrian-vehicle crashes [33]. The presence of a centreline was also found to decrease injury severity in bicycle-vehicle crashes, both at intersections and non-intersections [34].…”

Single and multi-vehicle crashes are a significant issue that causes economic and social costs and has therefore gained attention. This study explored the factors associated with injury severity for both single- and multi-vehicle crashes using over 550,000 crash data points in Japan between 2019 and 2021. We identified the determinants of road infrastructure and traffic control while controlling for driver, vehicle, environmental, and accident characteristics by applying ordered logit and bias-reduced binomial regression models. Our findings are as follows. 1) Traffic control variables did not affect single-vehicle crashes. 2) Guardrails had a higher severity in both single-vehicle crashes and multi-vehicle crashes at intersections. 3) The impact of the centerline differed between intersections and non-intersections for multi-vehicle crashes. These results of this study provide transportation agencies with important guidance as to the road infrastructure and transport control.

“…After checking the correlations among variables, we included an interaction term to account for potential variations, based on the surrounding environment [33,34]. We incorporated the Bayesian information criterion (BIC) for selecting the most appropriate model.…”

“…M. Tanishita and his team [21] investigated the impact of traffic control and road infrastructure on bystander severity in Japan. The authors applied logistic linear regression and determined that medians over intersections increased crash severity, on the other hand, they analyzed the intermittency of traffic lights (when the time to cross is about to end for the red light to turn on), and found an increase in severity over flashing traffic lights versus stop lights (stop sign).…”

The transportation sector has been fundamental in Colombia and faces serious consequences in terms of traffic accidents. This paper examines the relationship between accidentability and most outstanding road infrastructure factors in ten urban stretches of Neiva in the period 2017-2018, following the inclusion and exclusion criteria of the International Road Assessment Program (IRAP) for developing countries in order to characterize the state of road infrastructure of the selected points. The results showed that the central sections of the city tend to be related to the day, time, type of vehicle and victim, attribute and direction of the road. The motorcyclist was the road actor most vulnerable to injuries and fatalities, Saturday and 8:00 am was where more crashes occurred. The road infrastructure factors contributing to accidents highlight the relevance of the environment in the city.
