Investigating the relationship between crash severity, traffic barrier type, and vehicle type in crashes involving traffic barrier

open access: yesJournal of Traffic and Transportation Engineering (English ed. Online), 2020
Roadside safety is one of the important components of highway systems due to its considerable rate of high-severity crashes. Traffic barriers play a key role in reducing the crash severity and saving more lives on roadsides but choosing an inappropriate ...

Crash Severity Prediction Using Two-Layer Ensemble Machine Learning Model for Proactive Emergency Management

open access: yesIEEE Access, 2020
Many unfortunate victims in road traffic crashes do not receive ideal treatment because their injury severity is not understood at an early stage. Swift crash severity prediction enables trauma and emergency centers to estimate the potential damage ...

Collective Risk Ranking of Highway Segments on the Basis of Severity-Weighted Crash Rates

open access: yesJournal of Advanced Transportation, 2020
This study is intended to focus on the major factors affecting traffic crash rates and severity levels, in addition to identifying crash-prone locations (i.e., black spots) based on the two indicators. The available crash data for different road segments

Crash Frequency Minimization with Severity Mitigation in Road Geometric Design Using Chance Constraint Programming Optimization

open access: yesJournal of Advanced Transportation, 2023
Crash frequency and crash severity are two major aspects of transportation safety. In this paper, we propose a decision-making scheme combining statistical analysis and optimization modeling to be used in transportation safety study.
