Vehicle collision risk assessment method in highway work zone based on trajectory data

The methodology employed provides a detailed quantification of collision likelihood and severity, offering a comprehensive analysis of vehicle collision risks in work zones and their spatial distribution characteristics. It also explores the relationship between these risks and vehicle motion parameters. The findings offer a scientific basis for identifying high-risk areas and formulating targeted safety improvement measures. Furthermore, the study provides crucial technical support and decision-making guidance for enhancing traffic safety in highway work zones.
