Freeway Tunnel Driving Risk Assessment: Combining Feature Dimensionality Reduction and Driving Style Classification

Abstract

AbstractDriving risk assessment in tunnels is not only fundamental for evaluating traffic safety but also a critical prerequisite for analyzing and understanding the formation mechanisms of vehicle operational risks. Based on naturalistic driving ...Practical ApplicationsThis study classifies drivers in the Xiaxiyao Tunnel of Wuyu Expressway into four types (conservative, moderate, aggressive-a, aggressive-b) through parameter extraction, dimensionality reduction and clustering methods. Based on this ...
