Simulation study on the road system of port collection and distribution in the harbor area

Abstract

This paper comprehensively considers the impact of both internal and external traffic environments on the collection and distribution road system in the harbor area. Utilizing Anylogic simulation software, we construct a test environment using Yulong Port’s collection and distribution scenario as a case study. The analysis examines the influence of changes in road construction and the growth of external traffic on the operational efficiency of the port’s road collection and distribution system. The results indicate that with the addition of new roads, the efficiency of car and freight vehicle operations improves, leading to a respective decrease in the average travel time within the system by 3.6% and 4.4%. However, under conditions where social traffic flow increases to 1.2 times, the average travel time of the traffic flow within the system significantly rises, and congestion occurs in the external traffic around the port. The findings of this research provide valuable decision-making insights for the construction of collection and distribution channels in port areas and the approval of governmental projects.
