Comprehensive Assessment Framework for Collision Risk in Wide-Range Expressway Diverging Area Using Two-Dimensional Vehicle Trajectory Data

Expressway diverging areas exhibit a higher vehicle collision risk than basic segments due to frequent weaving and diverging traffic. Existing studies rely on 1D indicators and focus on the exit ramp and adjacent downstream sections, underestimating collision risks in wide-range diverging areas. This study proposes a...
