Optimization Method for Traffic Management in Port Distribution Road Work Zones Using the SUMO Simulation Platform

Lane closures during the maintenance of port distribution road work zones lead to vehicle queues, severely affecting port efficiency and increasing traffic congestion and accident risks. To address this issue, this study proposes a work zone traffic control scheme centered on lane merging control. By optimizing the combination and placement of variable message signs (VMS) and audio signal announcements, the impact of road maintenance on logistics transportation can be mitigated. Through driving simulation experiments and SUMO simulation software, this study develops Multinomial Logit (MNL) and Nested Logit (NL) models to analyze the key factors influencing drivers’ lane-changing decisions. The simulation results indicate that appropriate audio signal announcements can significantly enhance traffic control effectiveness. Particularly under high traffic pressure, setting up lane-change prompts in advance can effectively improve road traffic efficiency and reduce accident rates. This study not only provides a scientific management strategy for the maintenance of port hinterland roads but also lays a solid foundation for improving the overall efficiency of port operations.
