Abstract
With limited public investment, phased investment strategies (2-lane or limited 4-lane configurations) are widely adopted in Vietnam. However, this model poses safety risks due to the lack of median barriers and continuous emergency lanes. This study analyzes and quantifies factors influencing traffic accident severity using 170 accident records from 2018-2025. Integrating descriptive statistics and hierarchical logistic regression, the research identifies heavy trucks as the primary vehicles in over 71% of collisions. The model reveals that accidents on weekdays pose a severity risk 2.445 times higher than on weekends. Notably, "vehicle overturn or run-off-road" accidents - a direct result of inadequate emergency lanes - increase the probability of severe outcomes by 4.178 times. These findings provide a scientific basis for prioritizing infrastructure upgrades and optimizing traffic management on phased expressways.
As U.S. cities expand multimodal transportation networks and pursue Vision Zero goals, crash severity among pedestrians and bicyclists remains a critical public safety challenge. Charlotte, NC, offers a timely case study given its rapid urban growth, rising active transportation demand, and commitment to Vision Zero. T...

This study analyzes road traffic accident risk in Tanzania and introduces a composite Regional Road Accident Risk Index (RARI), defined as accidents per 100 km of road, to compare regional risk and assess progress toward SDG 3.6. A multi-method approach was used: national traffic fatality trends from 2000–2022 were mod...

Using annual national-level data for Poland (2010–2024), this study applies Hansen’s threshold regression framework to identify the point at which the historical positive relationship between motorisation and road traffic accidents reversed sign. A statistically significant and robust structural break is detected in 20...

Road traffic accidents continue to be a leading public safety concern in urban areas, and particularly for vulnerable road users including pedestrians and motorcyclists. While the increasing fatality and casualty counts urge a comprehensive approach to understand the factors contributing to crash risks, only a few stud...

Abstract Iran experiences notably high rates of road crashes, particularly on suburban roads. This study analysed 27,729 crash records from the Isfahan Province Traffic Police, collected between 2018 and 2020, to identify factors influencing crash severity and distinguish between fatal and non-fatal incidents. Using Ch...

Horizontal curves are a significant contributor to crash risk on rural road networks. Historically, high-risk curves are identified reactively, based on examination of crash history. However, to reduce the influence of random variation in observed crashes, proactive approaches, which estimate underlying crash risk, are...
